When starting a DnD operation, mutter would remove keyboard focus from
the client, only to restore it on the data offer destroy.
However, if the DnD fail, the keyboard focus is not restored, leaving
the user unable to type in the focused window, even after clicking in
the window.
That issue would show only on first attempt, as further DnD attempts
would destroy the previous data offer which would also restore the
keyboard focus.
Make sure we restore the keyboard focus on drag end as well.
https://gitlab.gnome.org/GNOME/mutter/issues/747
On drag start, `data_device_start_drag()` issues a keyboard grab, which
in turn will unset the current input focus.
There is not need to unset the input focus in `data_device_start_drag()`
as this is redone in `meta_wayland_keyboard_start_grab()`
https://gitlab.gnome.org/GNOME/mutter/issues/747
Currently, Clutter does picking by drawing with Cogl and reading
the pixel that's beneath the given point. Since Cogl has a journal
that records drawing operations, and has optimizations to read a
single pixel from a list of rectangle, it would be expected that
we would hit this fast path and not flush the journal while picking.
However, that's not the case: dithering, clipping with scissors, etc,
can all flush the journal, issuing commands to the GPU and making
picking slow. On NVidia-based systems, this glReadPixels() call is
extremely costly.
Introduce geometric picking, and avoid using the Cogl journal entirely.
Do this by introducing a stack of actors in ClutterStage. This stack
is cached, but for now, don't use the cache as much as possible.
The picking routines are still tied to painting.
When projecting the actor vertexes, do it manually and take the modelview
matrix of the framebuffer into account as well.

If window decoration is modified within a short period of time, mutter
sometimes starts processing the second request before the first
UnmapNotify event has been received. In this situation, it considers
that the window is not mapped and does not expect another UnmapNotify /
MapNotify event sequence to happen.
This adds a separate counter to keep track of the pending reparents. The
input focus is then restored when MapNotify event is received iff all
the expected pending ReparentNotify events have been received.

Threaded swap wait was added for using together with the Nvidia GLX
driver due to the lack of anything equivalent to the INTEL_swap_event
GLX extension. The purpose was to avoid inhibiting the invocation of
idle callbacks when constantly rendering, as the combination of
throttling on swap-interval 1 and glxSwapBuffers() and the frame clock
source having higher priority than the default idle callback sources
meant they would never be invoked.
This was solved in gbz#779039 by introducing a thread that took care of
the vsync waiting, pushing frame completion events to the main thread
meaning the main thread could go idle while waiting to draw the next
frame instead of blocking on glxSwapBuffers().
As of https://gitlab.gnome.org/GNOME/mutter/merge_requests/363, the
main thread will instead use prediction to estimate when the next frame
should be drawn. A side effect of this is that even without
INTEL_swap_event, we would not block as much, or at all, on
glxSwapBuffers(), as at the time it is called, we have likely already
hit the vblank, or will hit it soon.
After having introduced the swap waiting thread, it was observed that
the Nvidia driver used a considerable amount of CPU waiting for the
vblank, effectively wasting CPU time. The need to call glFinish() was
also problematic as it would wait for the frame to finish, before
continuing. Due to this, remove the threaded swap wait, and rely only on
the frame clock not scheduling frames too early.

This reverts commit f57ce7254d.
It causes crashes, https://gitlab.gnome.org/GNOME/mutter/issues/735, and
changes various expectations relied upon by the renderer code, and being
close to release, it's safer to revert now and reconsider how to remove
the pending swap counter at a later point.
Since Clutter's backend relies on MetaBackend now, initialzation has
to go through meta_init(), both in mutter and in gnome-shell.
However the compositor enum and backend gtype used to enforce the
environment used for tests are private, so instead expose a test
initialization function that can be used from both mutter and
gnome-shell.

If an application provides its window icon via wmhints, then mutter
loads the pixmap specified by the application into a cairo xlib surface. When
creating the surface it specifies the visual, indirectly, via an XRender
picture format.
This is suboptimal, since XRender picture formats don't have a way to specify
16bpp depth, which an application may be using.
In particular, applications are likely to use 16bpp depth pixmaps for their
icons, if the video card offers a 16bpp framebuffer/root window.
This commit drops the XRender middleman, and just tells cairo a visual to use
directly.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/715
This currently uses a hack where it pushes a CoglFramebuffer backed by a
texture to the framebuffer stack, then calls clutter_actor_paint() on
the window actor causing it to render into the framebuffer. This has the
effect that all subsurfaces of a window will be drawn as part of the
window.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/752
We are really more interested in when a window is damaged, rather than
when it's painted, for screen casting windows. This also has the benefit
of not listening on the "paint" signal of the actor, meaning it'll open
doors for hacks currently necessary for taking a screenshot of a window
consisting of multiple surfaces.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/752
Make it possible to listen for damage on a window actor. For X11, the

Flatten the subsurface actor tree, making all surface actors children
of the window actor.
Save the subsurface state in a GNode tree in MetaWaylandSurface, where
each surface holds two nodes, one branch, which can be the tree root
or be attached to a parent surfaces branch, and a leaf, which is
used to save the position relative to child branch nodes.
Each time a surface is added or reordered in the tree, unparent all
surface actors from the window actor, traverse all leaves of the
tree and readd the corresponding surface actors back to the window
actor.

This object can be generally triggered without a X11 display, so make sure

The surface offset allows an application to move itself in relative
coordinates to its previous position. It is rather ill defined and
partly incompatible with other functionality, which is why we ignore
it generally.
For dnd-surfaces though, it is the de-facto standard for applications
to properly position the dnd-icon below the cursor. Therefore apply
the offset on actor sync by setting the feedback actor anchor.

Commit b12c92e206 ("wayland: Add MetaWaylandSurface::geometry-changed signal")
Added a "geometry-changed" signal on MetaWaylandSurface, but the matching
changes to src/wayland/meta-pointer-confinement-wayland.c made it listen
for geometry-changed on the surface-actor instead of on the surface itself,
leading to errors like these:

When a dwell click causes the pointer to move to another surface, a
synthetic event is generated which triggers another dwell click.
Make sure we ignore those to avoid dwell clicking twice in a raw.
Suggested-by: Carlos Garnacho <carlosg@gnome.org>
https://gitlab.gnome.org/GNOME/mutter/merge_requests/747
Restarting the dwell click immediately would result in a contant
animation showing.
Start dwell detection in its own timeout handler, which has the nice
effect of not constantly showing a dwell animation and also making sure
that the dwell click timeout is started when pointer movement stops.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/747
Sometimes the dwell timeout doesn't start again after quickly moving the
pointer. That happens if `should_stop_dwell` returns TRUE for the last
motion event we receive: It will stop the current timeout, but not start
a new one until we receive another event where the moved distance is
smaller than the threshold.
To fix this, always call `should_start_dwell` and `start_dwell_timeout`
instead of using an else-block, this makes sure we start a new dwell
timeout still during the same motion event that stopped the old one.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/746
And add the necessary glue so those initialize a X11 clutter backend.

The end goal is to have all clutter backend code in src/backends. Input

This was supposed to be nice and incremental, but there's no sane way
to cut this through. As a result of the refactor, a number of private
Clutter functions are now exported for external backends to be possible.

Geometry scale is applied to each surface individually, using
Clutter scales, and not only this breaks subsurfaces, it also
pollutes the toolkit and makes the actor tree slightly too
fragile. If GNOME Shell mistakenly tries to set the actor scale
of any of these surfaces, for example, various artifacts might
happen.
Move geometry scale handling to MetaWindowActor. It is applied
as a child transform operation, so that the Clutter-managed
scale properties are left untouched.
In the future where the entirety of the window is managed by a
ClutterContent itself, the geometry scale will be applied
directly into the transform matrix of MetaWindowActor. However,
doing that now would break the various ClutterClones used by
GNOME Shell, so the child transform is an acceptable compromise
during this transition.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
meta_shaped_texture_update_area() is a private function that
is exposed in the public headers. It is not used anywhere
outside Mutter, and should really be in the private header.
Move it to the private header.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
Now that MetaShapedTexture is not a ClutterActor anymore, it does
not make sense to make it a MetaCullable semi-implementation. This
is, naturally, a responsibility of MetaSurfaceActor, since now
MetaShapedTexture is a ClutterContent and as such, it only cares
about what to draw.
Move the MetaCullable implementation of MetaShapedTexture to
MetaSurfaceActor.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
By implementing ClutterContent, it is expected that
MetaShapedTexture can draw on any actor. However,
right now this is not possible, since it assumes
that the drawing coordinates and sizes of the actor
are synchronized with its own reported width and
height.
It mistakenly draws, for example, when setting an
actor's content to it. There is no way to trigger
this wrong behavior right now, but it will become
a problem in the future where we can collect the
paint nodes of MetaShapedTexture as part of other
ClutterContent implementations.
Use the allocation box passed by the actor to draw
the pipelines of MetaShapedTexture.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
Now that MetaShapedTexture is a ClutterContent implemetation that
is aware of its own buffer scale, it is possible to simplify the
event translation routines.
Set the geometry scale in MetaSurfaceActor, and stop adjusting the
surface scale when translating points. Also remove the now obsoleted
meta_wayland_actor_surface_calculate_scale() function.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
MetaWindowActor is the compositor-side representative of a
MetaWindow. Specifically it represents the geometry of the
window under Clutter scene graph. MetaWindowActors are backed
by MetaSurfaceActors, that represent the windowing system's
surfaces themselves. Naturally, these surfaces have textures
with the pixel content of the clients associated with them.
These textures are represented by MetaShapedTexture.
MetaShapedTextures are currently implemented as ClutterActor
subclasses that override the paint function to paint the
textures it holds.
Conceptually, however, Clutter has an abstraction layer for
contents of actors: ClutterContent. Which MetaShapedTexture
fits nicely, in fact.
Make MetaShapedTexture a ClutterContent implementation. This
forces a few changes in the stack:
* MetaShapedTexture now handles buffer scale.
* We now paint into ClutterPaintNode instead of the direct
framebuffer.
* Various pieces of Wayland code now use MetaSurfaceActor
instead of MetaShapedTexture.
* MetaSurfaceActorWayland doesn't override size negotiation
vfuncs anymore
https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
Mutter needs to know which framebuffer the paint nodes will be
drawn into, and using cogl_get_draw_framebuffer() directly is
not an option since ClutterRootNode only pushes the draw fb
at draw time.
Expose clutter_paint_node_get_framebuffer().
https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
One of the man pages is now generated using asciidoc, which is missing

Incompressible events already pass through unmodified, so queuing them
just wasted time and memory.
We would however like to keep the ordering of events so we can only
apply this optimization if the queue is empty.
This reduces the input latency of incompressible events like touchpad
scrolling or drawing tablets by up to one frame. It also means the same
series of events now arrives at the client more smoothly and not in
bursts.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/711
Until now we would:
1. Enqueue modifier key event on the stage.
2. Update device modifier state.
3. Dequeue and process modifier key event with NEW device modifier state.
But if we consider optimizing out the queuing in some cases then there
will become a problem:
1. Process modifier key event with OLD device modifier state.
2. Update device modifier state.
To correct the above we now do:
1. Update device modifier state.
2. Queue/process modifier key event with NEW device modifier state.
It appears commit dd940a71 which introduced the old behaviour was correct
in the need to update the device modifier state, but is at least no longer
correct (if it ever was) that it should be done after queuing the event.
If queuing is working, as it is right now, then it makes no difference
whether the device modifier state is updated before or after. Because both
cases will come before the dequeing and processing.

Thanks to the now removed global/context grabs, we can move pointer and

With the addition of xauth support (commit a8984a81c), Xwayland would
rely only on the provided cookies for authentication.
As a result, running an Xclient from another VT (hence without the
XAUTHORITY environment variable set) would result in an access denied.
The same on X11 is granted because the local user is automatically
granted access to Xserver by the startup scripts.
Add the local user to xhost at startup on Xwayland so that the user can
still run a client by setting the DISPLAY as long as it's the same user
on the same host.

If possible, GLib will try to use the va_marshaller to pass the signal
arguments, rather than unboxing into and out of a `GValue`. This is much
more performant and especially good for often-thrown signals.
The original bug even mentions Clutter performance issues as a drive to
implement the va_marshaller in GLib (see
https://bugzilla.gnome.org/show_bug.cgi?id=661140).
https://gitlab.gnome.org/GNOME/mutter/merge_requests/700
Some of the marshallers we generate in `clutter-marshal.list` are also
available in GLib, so we don't need to generate them ourselves. Even
more, by passing NULL to `g_signal_new` in these cases will actually
internally optimize this even more by also setting the valist
marshaller, which is a little bit faster than the regular marshalling
using `GValue` and libffi.

When double clicking to un-maximize an X11 window under Wayland, there
is a race between X11 and Wayland protocols and the X11 XConfigureWindow
may be processed by Xwayland before the button press event is forwarded
via the Wayland protocol.
As a result, the second click may reach another X11 window placed right
underneath in the X11 stack.
Make sure we do not forward the button press event to Wayland if it was
handled by the frame UI.

Adds initial GLES2 integration support
This makes it possible to integrate existing GLES2 code with
applications using Cogl as the rendering api.
That's maybe a reasonable thing for a standalone cogl to want, but our
cogl has only one consumer. So if we want additional rendering out of
our cogl layer, it makes more sense to just add that to cogl rather than
support clutter or mutter or the javascript bindings creating their own
GLES contexts.

Add meta-kms and meta-monitor-manager-kms listener for the udev
device-removed signal and on this signal update the device state /
re-enumerate the monitors, so that the monitors properly get updated
to disconnected state on GPU removal.
We really should also have meta-backend-native remove the GPU itself
from our list of GPU objects. But that is more involved, see:
https://gitlab.gnome.org/GNOME/mutter/issues/710
This commit at least gets us to a point where we properly update the
list of monitors when a GPU gets unplugged; and where we no longer
crash the first time the user changes the monitor configuration after
a GPU was unplugged.
Specifically before this commit we would hit the first g_error () in
meta_renderer_native_create_view () as soon as some monitor
(re)configuration is done after a GPU was unplugged.

drmModeGetConnector may fail and return NULL, this may happen when
a connector is removed underneath us (which can happen with e.g.

drmModeGetCrtc may fail and return NULL. This will trigger when
meta_kms_crtc_update_state gets called from meta_kms_update_states_sync
after a GPU has been unplugged leading to a NULL pointer deref causing
a crash.
This commit fixes this by checking for NULL and clearing the current_state
when NULL is returned.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/713
Before this commit meta_kms_crtc_read_state was overwriting the
entire MetaKmsCrtcState struct stored in crtc->current_state including
the gamma (sub)struct.
This effectively zero-s the gamma struct each time before calling
read_gamma_state, setting the pointers where the previous gamma values
were stored to NULL without freeing the memory. Luckily this zero-ing
also sets gamma.size to 0, causing read_gamma_state to re-alloc the
arrays on each meta_kms_crtc_update_state call. But this does mean that
were leaking the old gamma arrays on each meta_kms_crtc_update_state call.
This commit fixes this by making meta_kms_crtc_read_state only overwrite
the other values in the MetaKmsCrtcState struct and leaving the gamma
sub-struct alone, this will make read_gamma_state correctly re-use the
gamma tables if the gamma table size is unchanged; or re-alloc them
(freeing the old ones) if the size has changed, fixing the memory leak.

The "device-added" signal should use g_cclosure_marshal_VOID__OBJECT not
g_cclosure_marshal_VOID__VOID.
Instead of fixing this manually, simply replace the closure function for

va_marshaller.

Some meta_later operations may happen across XWayland being shutdown,
that trigger MetaStackTracker queries for X11 XIDs. This crashes as
the MetaX11Display is already NULL.
Return a NULL window in that case, as in "unknown stack ID".
https://gitlab.gnome.org/GNOME/mutter/merge_requests/728
There may be cases where a X11 client does not spawn any X11 windows (eg.
simple clients like xinput --list, or xlsclients), in this case the Xwayland
server would remain running until X11 windows happen to come and go in the
future.
Firing the shutdown timeout on restart caters for this, and would be undone
if the client maps X11 windows.

Where the prepare_auth_file() call is, it does create a new one on every

We only listen for those so we know there's no more X11 clients that we

superfluous, even harmful.
https://gitlab.gnome.org/GNOME/mutter/issues/719
The Xwayland manager now has 4 distinct phases:
- Init and shutdown (Happening together with the compositor itself)
- Start and stop
In these last 2 phases, handle orderly initialization and shutdown
of Xwayland. On initialization We will simply find out what is a
proper display name, and set up the envvar and socket so that clients
think there is a X server.
Whenever we detect data on this socket, we enter the start phase
that will launch Xwayland, and plunge the socket directly to it.
In this phase we now also set up the MetaX11Display.
The stop phase is pretty much the opposite, we will shutdown the
MetaX11Display and all related data, terminate the Xwayland
process, and restore the listening sockets. This phase happens
on a timeout whenever the last known X11 MetaWindow is gone. If no
new X clients come back in this timeout, the X server will be
eventually terminated.
The shutdown phase happens on compositor shutdown and is completely
uninteresting. Some bits there moved into the stop phase as might
happen over and over.
This is all controlled by META_DISPLAY_POLICY_ON_DEMAND and
the "autostart-xwayland" experimental setting.

When rushing to unmanage X11 windows after the X11 connection is closed/ing,
this would succeed at creating a stack operation for no longer known windows.
Simply avoid to queue a stack operation if we know it's meaningless.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/709
Unmanaging the windows may trigger stack operations that we later try
to synchronize despite being in dispose() stage. This may trigger
MetaStackTracker warnings when trying to apply those operations.
Switching destruction order (First dispose the X11 stack representation,
then unmanage windows) won't trigger further stack changes on X11 windows
after having signaled MetaDisplay::x11-display-closing.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/709
What "restart" means is somewhat different between x11 and wayland
sessions. A X11 compositor may restart itself, thus having to manage
again all the client windows that were running. A wayland compositor
cannot restart itself, but might restart X11, in which case there's
possibly a number of wayland clients, plus some x11 app that is
being started.
For the latter case, the assert will break, so just make it
conditional. Also rename the function so it's more clear that it
only affects X11 windows.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/709
In the case mutter is a x11 compositor, it doesn't matter much
since the stack tracker will go away soon. In the case this is a
wayland compositor with mandatory Xwayland, it matters even less
since the session would be shutting down in those paths.
But if this a wayland compositor that can start Xwayland on demand,
this is even harmful, as the MetaStackTracker should be cleared of
x11 windows at this moment, and we actually did right before dispose
on ::x11-display-closing.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/709
If the display is closed prematurely, go through all windows that
look X11-y and remove them for future calculations. This is not
strictly needed as Xwayland should shut down orderly (thus no client
windows be there), but doesn't hurt to prepare in advance for the
cases where it might not be the case.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/709
We don't strictly need it for wayland compositors, yet there are
paths where we try to trigger those passive grabs there. Just
skip those on the high level code (where "is it x11" decisions
are taken) like we do with passive button grabs.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/709
Commit 09bab98b1e tried to avoid several workspace changes while in
window construction, but it missed a case:
If we have a window on a secondary monitor with no workspaces enabled
(so it implicitly gets on_all_workspaces = TRUE without requesting it)
and trigger the creation of a second window that has the first as
transient-for, it would first try to set the first workspace than the
transient-for window and then fallback to all/current workspace.
After that commit we only try to set the same workspace than the
transient-for window, but it gets none as neither is on a single workspace,
nor did really request to be on all workspaces.
Fixes crashes when opening transient X11 dialogs in the secondary monitor.

Similar to gtk commit f507a790, this ensures that the valist variant of
the marshaller is used. From that commit's message:
```
If we set c_marshaller manually, then g_signal_newv() will not setup a
va_marshaller for us. However, if we provide c_marshaller as NULL, it will
setup both the c_marshaller (to g_cclosure_marshal_VOID__VOID) and
va_marshaller (to g_cclosure_marshal_VOID__VOIDv) for us.
```
https://gitlab.gnome.org/GNOME/mutter/merge_requests/697
By putting `NULL` as the C marshaller in `g_signal_new`, you
automatically get `g_cclosure_marshaller_generic`, which will try to
process its arguments and return value with the help of libffi and
GValue.
Using `glib-genmarshal` and valist_marshallers, we can prevent this so
that we need less instructions for each signal emission.

Double negations are the spawn of the devil, and is_non_opaque() is

The MetaBackgroundActor was ignoring the unobscured area altogether,
and just painted according to the clip area. Check the unobscured

Wayland clients do this through the opaque region in the surface
actor. However X11 clients were considered fully transparent for
culling purposes, which may result in mutter painting other bits
of the background or other windows that will be painted over in
reality.

We want to clip it away if 1) The window is fully opaque or
2) If it's translucent but has a frame (as explained in the comment
above). The code didn't quite match and we were only applying it on

Case #1 is far more common, and saves us from pushing some drawing
that we know will be covered in the end.

`g_object_notify()` actually takes a global lock to look up the property

We first set the workspace to the transient-for parent's, and then

The default configuration of libinput-gestures utility invokes wmctrl to
switch between desktops. It uses wmctrl because this works on both Xorg
and Wayland (via XWayland). Unfortunately, this generates the following
warning message every time, in both Xorg and Wayland desktops:
"Received a NET_CURRENT_DESKTOP message from a broken (outdated) client
who sent a 0 timestamp"
The desktop switch still works fine. The tiny code change here removes
this specific warning because, as the prefacing code comment originally
said and still says, older clients can validly pass a 0 time value so
why complain about that?
I also refactored the "if (workspace)" code slightly to avoid the double
test of the workspace value.
This is submitted for MR
https://gitlab.gnome.org/GNOME/mutter/merge_requests/671.
On X11, mutter needs to keep a grab on the locate-pointer key to be able
to trigger the functionality time the corresponding key combo is
pressed.
However, doing so may have side effects on other X11 clients that would
want to have a grab on the same key.
Make sure we only actually grab the key combo for "locate-pointer" only
when the feature is actually enabled, so that having the locate pointer
feature turned off (the default) would not cause side effects on other
X11 clients that might want to use the same key for their own use.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/647
Some special modifiers (typically "Control_L" used for locate-pointer in
mutter/gnome-shell or "Super_L" for overlay) must be handled separately
from the rest of the key bindings.
Add a new flag `META_KEY_BINDING_NO_AUTO_GRAB` so we can tell when
dealing with that special keybinding which should not be grabbed
automatically like the rest of the keybindings, and skip those when
changing the grabs of all keybindings.

The type has been deprecated, so stop using it. The easiest replacement

Glib stopped providing any fallback implementations on systems without

Starting with commit 2db94e2e we try to focus a fallback default focus window
if no take-focus window candidate gets the input focus when we request it and
we limit the focus candidates to the current window's workspace.
However, if the window is unmanaging, the workspace might be unset, and we could
end up in deferencing a NULL pointer causing a crash.
So, in case the window's workspace is unset, just use the currently active
workspace for the display.

This is important when using a touchscreen or stylus instead of a mouse
or touchpad. If the cursor only gets hidden and the focus stays the
same, the window will still send hover events to the UI element under
the cursor causing unexpected distractions while interacting with the
touchscreen.
Fix this by emitting a visibility-changed signal from the cursor tracker
which then triggers a focus surface sync and always set the focus
surface to NULL when it's synced while the cursor is hidden.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/448
Allow checking whether the pointer is visible without accessing the
trackers internal is_showing property. While we don't need this just yet
for reading the visibility inside meta-wayland-pointer, it's useful when
implementing the logic to remove Clutter's focus when the cursor goes
hidden later.

COPY_MODE_PRIMARY has two paths, automatically chosen. For debugging purposes,
e.g. why is my DisplayLink screen slowing down the whole desktop, it will be
useful to know which copy path is taken. Debug prints are added to both when
the primary GPU copy succeeds the first time and when it fails the first time.
This is not the full truth, because theoretically the success/failure could
change every frame, but we don't want to spam the logs (even in debug mode)
every frame. In practise, it should be rare for the success or failure to ever
change. Hence, saying what happened on the first time is enough. This does
indicate if it ever changes even once, too, so we know if that unexpected thing
happens.
The debug prints are per secondary GPU since there could be several.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/615
When the preferred path META_SHARED_FRAMEBUFFER_COPY_MODE_SECONDARY_GPU cannot
be used, as is the case for e.g. DisplayLink devices which do not actually have
a GPU, try to use the primary GPU for the copying before falling back to
read-pixels which is a CPU copy.
When the primary GPU copy works, it should be a significant performance win
over the CPU copy by avoiding stalling libmutter for the duration.
This also renames META_SHARED_FRAMEBUFFER_COPY_MODE_* because the new names are
more accurate. While the secondary GPU copy is always a GPU copy, the primary
copy might be either a CPU or a GPU copy.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/615
This bit of code was more or less duplicated in meta-renderer-native-gles3.c
and meta-wayland-dma-buf.c. Start consolidating the two implementations by
moving the *-gles3.c function into meta-egl.c and generalizing it so it could
also accommodate the meta-wayland-dma-buf.c usage.
The workaround in the *-gles3.c implementation is moved to the caller. It is
the caller's responsibility to check for the existence of the appropriate EGL
extensions.
Commit 6f59e4858e worked around the lack of
EGL_EXT_image_dma_buf_import_modifiers with the assumption that if the modifier
is linear, there is no need to pass it into EGL. The problem is that not
passing a modifier explicitly to EGL invokes implementation-defined behaviour,
so we should not have that workaround in meta-egl.c.
This patch intends to be pure refactoring, no behavioral changes. The one
change is the addition of g_assert to catch overwriting arbitrary memory.

The function will be used in copying from a primary GPU framebuffer to a

Depends on "cogl: Replace ANGLE with GLES3 and NV framebuffer_blit"
Allow blitting between onscreen and offscreen framebuffers by doing the y-flip
as necessary. This was not possible with ANGLE, but now with ANGLE gone,
glBlitFramebuffer supports flipping the copied image.
This will be useful in follow-up work to copy from onscreen primary GPU
framebuffer to an offscreen secondary GPU framebuffer.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/615
Depends on: "cogl: Replace ANGLE with GLES3 and NV framebuffer_blit"
As a possible ANGLE implementation is not longer limiting the pixel format
matching, lift the requirement of having the same pixel format.
We still cannot do a premult <-> non-premult conversion during a blit, so guard
against that.
This will be useful in follow-up work to copy from onscreen primary GPU
framebuffer to an offscreen secondary GPU framebuffer if the formats do not
match exactly.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/615
ANGLE extensions are only provided by Google's Almost Native Graphics Layer
Engine (ANGLE) implementation. Therefore they do not seem too useful for
Mutter.
The reason to drop GL_ANGLE_framebuffer_blit support is that it has more
limitations compared to the glBlitFramebuffer in GL_EXT_framebuffer_blit,
GL_NV_framebuffer_bit, OpenGL 3.0 and OpenGL ES 3.0. Most importantly, the
ANGLE version cannot flip the image while copying, which limits
_cogl_blit_framebuffer to only off-screen <-> off-screen copies. Follow-up work
will need off-screen <-> on-screen copies.
Instead of adding yet more capability flags to Cogl, dropping ANGLE support
seems appropriate.
The NV extension is added to the list of glBlitFramebuffer providers because it
provides the same support as ANGLE and more.
Likewise OpenGL ES 3.0 is added to the list of glBlitFramebuffer providers
because e.g. Mesa GLES implementation usually provides it and that makes it
widely available, again surpassing the ANGLE supported features.
Follow-up patches will lift some of the Cogl assumptions of what
glBlitFramebuffer cannot do.

Using the master device, as we did, won't yield the expected result when

Currently nothing in the clutter machinery prevents hidden portions
of the actor tree from calling queue_relayout() (and having it fully
honored).
But that allocation should not be necessary till the actor is shown,
and one of the things we do on show() is queueing a relayout/redraw
after flagging the actor as visible.
We can simply defer clutter_actor_allocate() calls till that show()
call, and leave the needs_allocate and other flags set so we ensure
the allocation is properly set then.
This should cut down some needless operations when invisible portions
of the actor tree change indirectly due to user interaction, or due
to background activity.

The device ID is kind of pointless on Wayland, so it might be better to

As per commit f71151a5 we focus an input window if no take-focus-window accepts
it. This might lead to an infinite loop if there are various focusable but
non-input windows in the stack.
When the current focus window is unmanaging and we're trying to focus a
WM_TAKE_FOCUS window, we intent to give the focus to the first focusable input
window in the stack.
However, if an application (such as the Java ones) only uses non-input
WM_TAKE_FOCUS windows, are not requesting these ones to get the focus. This
might lead to a state where no window is focused, or a wrong one is.
So, instead of only focus the first eventually input window available, try to
request to all the take-focus windows that are in the stack between the
destroyed one and the first input one to acquire the input focus.
Use a queue to keep track of those windows, that is passed around stealing
ownership, while we protect for unmanaged queued windows.
Also, reduce the default timeout value, as the previous one might lead to an
excessive long wait.
Added metatests verifying these situations.

When used it setups an X11 event monitor that replies to WM_TAKE_FOCUS

As per commit f71151a5 we were ignoring WM_TAKE_FOCUS-only windows as focus
targets, however this might end-up in an infinite loop if there are multiple

take-focus one (that might not reply to the request).
Added a stacking test to verify this.

Since 4cae9b5b11, and indirectly before that as well, the

As per commit 040de396b, we don't try to grab when shortcuts are inhibited,
However, this uses the focus window assuming that it is always set, while this
might not be the case in some scenarios (like when unsetting the focus before
requesting take-focus-window to acquire the input).
So allow the button grab even if the focus window is not set for the display
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/663https://gitlab.gnome.org/GNOME/mutter/merge_requests/668
On Wayland, if a client issues a inhibit-shortcut request, the Wayland
compositor will disable its own shortcuts.
We should also disable the default handler for the button grab modifier
so that button events with the window grab modifiers pressed are not
caught by the compositor but are forwarded to the client surface.
That also fixes the same issue with Xwayland applications issuing grabs,
as those end up being emulated like shortcut inhibition.

gnome-shell hardcodes a vertical one-column workspace layout, and

The way code was structured made it easy to misunderstand things as the
surface actor of a window actor could change over time. So is not the
case, however, the intention of the corresponding "update" function was
so that a surface actor could be assigned to a window actor as soon as
the X11 window was associated with its corresponding wl_surface, if the
window in question came from Xwayland.
Restructure the code and internal API a bit to make it clear that a
window actor only once gets a surface actor assigned to it, and that it
after that point never changes.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/659
X11 actors need to release the server data (pixmap and damage) before the
display is closed.
During the close phase all the windows are unmanaged and this causes the window
actors to be removed from the compositor, unsetting their actor surface.
However, in case a window is animating the surface might not be destroyed until
the animation is completed and a reference to it kept around by gjs in the shell
case. By the way, per commit 7718e67f all window actors (even the animating
ones) are destroyed before the display is closed, but this is not true for the
child surface, because the parent window will just unref it, leaving it around
if reffed somewhere else. This is fine for wayland surfaces, but not for X11
ones which are bound to server-side pixmaps.
So, connect to the parent MetaWindowActor "destroy" signal, releasing the x11
resources that implies detaching the pixmap (unsetting the texture) and removing
the damages.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/629https://gitlab.gnome.org/GNOME/mutter/merge_requests/660
free_damage and detach_pixmap functions are called inside dispose and an object
can be disposed multiple times, even when the display is already closed.
So, don't try to deference a possibly null-pointer, assigning the xdisplay too
early, as if the X11 related resources have been unset, the server might not be
open anymore. In fact, we assume that if we have a damage or a pixmap set,
the display is still open.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/660
In MetaWindowActor creation we're setting the compositor private (i.e. the
window actor itself) of a window before creating the surface actor, and so
passing to the it a window without its compositor side set.
Since the surface actor might use the parent actor, set this before updating
the surface.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/660
As per commit 80e3c1d set_surface_actor has been added, meant to do different
things depending on the backend, like connecting to signals under X11.

repaint-scheduled signal.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/660
Everytime the top window changes we connect/disconnect to the actor's destroy
signal, although as explained in commit ba8f5a11 this might be slower in case
the window actor has many other signal connections.

There were fallbacks in place in case IN_FORMATS didn't yield any usable

is seen:

Public functions in C should be declared before they are defined, and
often compilers warn you if you haven't:

In this case the function declarations were not included because
`HAVE_TRACING` isn't defined. But we should still include `cogl-trace.h`
because it handles the case of `HAVE_TRACING` not being defined and
correctly still declares the functions defined in `cogl-trace.c`.

When requesting to a take-focus window to acquire the input, the client may or
may not respond with a SetInputFocus (this doesn't happen for no-input gtk
windows in fact [to be fixed there too]), in such case we were unsetting the
focus while waiting the reply.
In case the client won't respond, we wait for a small delay (set to 250 ms) for
the take-focus window to grab the input focus before setting it to the default
window.
Added a test for this behavior and for the case in which a window takes the
focus meanwhile we're waiting to focus the default window.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/307
This allows to sleep for a given timeout in milliseconds.
Rename test_case_before_redraw to test_case_loop_quit since it's a generic
function and use it for the timeout too.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/307
This allows to verify which window should have the focus, which might not
be the same as the top of the stack.
It's possible to assert the case where there's no focused window using
"NONE" as parameter.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/307
Allow to set/unset WM_TAKE_FOCUS from client window.
This is added by default by gtk, but this might not happen in other toolkits,
so add an ability to (un)set this.
So fetch the protocols with XGetWMProtocols and unset the atom.
test-client now needs to depend on Xlib directly in meson build.

When destroying a window that has a parent, we initially try to focus one of
its ancestors. However if no ancestor can be focused, then we should instead
focus the default focus window instead of trying to request focus for a window
that can't get focus anyways.

On FreeBSD, gethostname is guarded by '__POSIX_VISIBLE >= 200112', which
requires either '_POSIX_C_SOURCE >= 200112' or '_XOPEN_SOURCE >= 600'.
Defining _XOPEN_SOURCE to 500 does not break the build because of
implicit declaration, but it defeats the purpose of defining the macro.

We get a signed integer (-1 meaning "no workspace specified"), store it in
an unsigned integer, check for >= 0 (of course it is!) and set as the window
workspace (signed integer, -1 meaning "show on all workspaces"). What could
possibly go wrong?

This commit introduces, and makes use of, a transactional API used for
setting up KMS state, later to be applied, potentially atomically. From
an API point of view, so is always the case, but in the current
implementation, it still uses legacy drmMode* API to apply the state
non-atomically.
The API consists of various buliding blocks:
* MetaKmsUpdate - a set of configuration changes, the higher level
handle for handing over configuration to the impl backend. It's used to
set mode, assign framebuffers to planes, queue page flips and set
connector properties.
* MetaKmsPlaneAssignment - the assignment of a framebuffer to a plane.
Currently used to map a framebuffer to the primary plane of a CRTC. In
the legacy KMS implementation, the plane assignment is used to derive
the framebuffer used for mode setting and page flipping.
This also means various high level changes:
State, excluding configuring the cursor plane and creating/destroying
DRM framebuffer handles, are applied in the end of a clutter frame, in
one go. From an API point of view, this is done atomically, but as
mentioned, only the non-atomic implementation exists so far.
From MetaRendererNative's point of view, a page flip now initially
always succeeds; the handling of EBUSY errors are done asynchronously in
the MetaKmsImpl backend (still by retrying at refresh rate, but
postponing flip callbacks instead of manipulating the frame clock).
Handling of falling back to mode setting instead of page flipping is
notified after the fact by a more precise page flip feedback API.
EGLStream based page flipping relies on the impl backend not being
atomic, as the page flipping is done in the EGLStream backend (e.g.
nvidia driver). It uses a 'custom' page flip queueing method, keeping
the EGLStream logic inside meta-renderer-native.c.
Page flip handling is moved to meta-kms-impl-device.c from
meta-gpu-kms.c. It goes via an extra idle callback before reaching
meta-renderer-native.c to make sure callbacks are invoked outside of the
impl context.
While dummy power save page flipping is kept in meta-renderer-native.c, the
EBUSY handling is moved to meta-kms-impl-simple.c. Instead of freezing the
frame clock, actual page flip callbacks are postponed until all EBUSY retries
have either succeeded or failed due to some other error than EBUSY. This
effectively inhibits new frames to be drawn, meaning we won't stall waiting on
the file descriptor for pending page flips.
https://gitlab.gnome.org/GNOME/mutter/issues/548https://gitlab.gnome.org/GNOME/mutter/merge_requests/525
The MetaKmsImpl implementation may need to add a GSource that should be
invoked in the right context; e.g. a idle callback, timeout etc. It
cannot just add it itself, since it's the responsibility of MetaKms to
determine what is the impl context and what is the main context, so add
API to MetaKms to ensure the callback is invoked correctly.
It's the responsibility of the caller to eventually remove and destroy
the GSource.

As with CRTC state, variable connector state is now fetched via the
MetaKmsConnector. The existance of a connector state is equivalent of
the connector being connected. MetaOutputKms is changed to fetch
variable connector state via MetaKmsConnector intsead of KMS directly.
The drmModeConnector is still used for constructing the MetaOutputKms to
find properties used for applying configuration.
https://gitlab.gnome.org/GNOME/mutter/issues/548https://gitlab.gnome.org/GNOME/mutter/merge_requests/525
Move reading state into a struct for MetaCrtcKms to use instead of
querying KMS itself. The state is fetched in the impl context, but
consists of only simple data types, so is made accessible publicly. As
of this, MetaCrtcKms construction does not involve any manual KMS
interaction outside of the MetaKms abstraction.
https://gitlab.gnome.org/GNOME/mutter/issues/548https://gitlab.gnome.org/GNOME/mutter/merge_requests/525
Represents drmModeConnector; both connected and disconnected. Currently
only provides non-changing meta data. MetaOutputKms is changed to use
MetaKmsConnector to get basic metadata, but variable metadata, those
changing depending on what is connected (e.g. physical dimension, EDID,
etc), are still manually retrieved by MetaOutputKms.

A plane is one of three possible: primary, overlay and cursor. Each
plane can have various properties, such as possible rotations, formats
etc. Each plane can also be used with a set of CRTCs.
A primary plane is the "backdrop" of a CRTC, i.e. the primary output for
the composited frame that covers the whole CRTC. In general, mutter
composites to a stage view frame onto a framebuffer that is then put on
the primary plane.
An overlay plane is a rectangular area that can be displayed on top of
the primary plane. Eventually it will be used to place non-fullscreen
surfaces, potentially avoiding stage redraws.
A cursor plane is a plane placed on top of all the other planes, usually
used to put the mouse cursor sprite.
Initially, we only fetch the rotation properties, and we so far
blacklist all rotations except ones that ends up with the same
dimensions as with no rotations. This is because non-180° rotations
doesn't work yet due to incorrect buffer modifiers. To make it possible
to use non-180° rotations, changes necessary include among other things
finding compatible modifiers using atomic modesetting. Until then,
simply blacklist the ones we know doesn't work.
https://gitlab.gnome.org/GNOME/mutter/issues/548https://gitlab.gnome.org/GNOME/mutter/merge_requests/525
Add MetaKmsCrtc to represent a CRTC on the associated device. Change
MetaCrtcKms to use the ones discovered by the KMS abstraction. It still
reads the resources handed over by MetaGpuKms, but eventually it will
use only MetaKmsCrtc.
MetaKmsCrtc is a type of object that is usable both from an impl task
and from outside. All the API exposed via the non-private header is
expected to be accessible from outside of the meta-kms namespace.
https://gitlab.gnome.org/GNOME/mutter/issues/548https://gitlab.gnome.org/GNOME/mutter/merge_requests/525
The intention with KMS abstraction is to hide away accessing the drm
functions behind an API that allows us to have different kind of KMS
implementations, including legacy non-atomic and atomic. The intention
is also that the code interacting with the drm device should be able to
be run in a different thread than the main thread. This means that we
need to make sure that all drm*() API usage must only occur from within
tasks that eventually can be run in the dedicated thread.
The idea here is that MetaKms provides a outward facing API other places
of mutter can use (e.g. MetaGpuKms and friends), while MetaKmsImpl is
an internal implementation that only gets interacted with via "tasks"
posted via the MetaKms object. These tasks will in the future
potentially be run on the dedicated KMS thread. Initially, we don't
create any new threads.
Likewise, MetaKmsDevice is a outward facing representation of a KMS
device, while MetaKmsImplDevice is the corresponding implementation,
which only runs from within the MetaKmsImpl tasks.
This commit only moves opening and closing the device to this new API,
while leaking the fd outside of the impl enclosure, effectively making
the isolation for drm*() calls pointless. This, however, is necessary to
allow gradual porting of drm interaction, and eventually the file
descriptor in MetaGpuKms will be removed. For now, it's harmless, since
everything still run in the main thread.

The “togglekeys” setting is to emit a sounds whenever the state of one
of the modifiers keys (CAPS lock, NUM Lock, SCROLL lock) is changed, it
has nothing to do with the rest of the accessibility settings.
Therefore, there is no need to reset the various timers used by
accessibility whenever the “togglekeys” setting is changed.

Before this commit, sudo x11-app, e.g. sudo gvim /etc/some-file, fails
when running a Wayland session. Where as doing this under a "GNOME on Xorg"
session works fine. For a user switching from the Xorg session to the

MetaStageWatch, watch modes and the watch function are part
of the new stage view watching API. It's design does not
rely on signals on purpose; the number of signals that would
be emitted would be too high, and would impact performance.
MetaStageWatch is an opaque structure outside of MetaStage.
This will be used by the screencast code to monitor a single
view, which has a one-to-one relatioship to logical monitors.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/623
ClutterStage:after-paint now does not guarantee a valid
implicit framebuffer pushed to the stack. Instead, use
the new 'paint-view' signal, that is emitted at a point
in the drawing routine where a framebuffer is pushed.
In addition to that, stop using the implicit framebuffer
API and port the actor-shader-effect test to read from
the view's framebuffer directly.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/623
Now that ClutterStageView is embraced as part of the public
set of Clutter classes, is it possible to give consumers
of this API more information and control over the drawing
routines of ClutterStage.
Introduce ClutterStage:paint-view, a signal that is emitted
for painting a specific view. It's defined as a RUN_LAST
signal to give anyone connecting to it the ability to run
before the view is actually painted, or after (using the
G_CONNECT_AFTER flag, or g_signal_connect_after).
This signal has a corresponding class handler, which allows
Mutter to have much finer control over the painting routines.
In fact, this will allow us to implement a "paint phase watcher"
mechanism in the following patches.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/623
ClutterStage:after-paint is supposed to be emitted after all
painting is done, but before the frame is finished. However,
as it is right now, it is being emitted after each view is
painted -- on multi-monitor setups, after-frame is being
emitted multiple times.
Send after-paint only once, after all views are painted and
before finishing the frame.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/623
As a compositor toolkit, it makes sense to allow consumers
of Clutter interact with the stage views themselves. As such,
ClutterStageView should be a public class.
As such, it is now included in clutter.h and should not be
included directly.

Currently the EGLDevice code gets the display and calls eglInitialize.
As a follow-up it checks the required EGL extensions - technically it
could check the EGL device extensions earlier.
In either case, eglTerminate is missing. Thus the connection to the
display was still bound.
This was highlighted with Mesa commit d6edccee8da ("egl: add
EGL_platform_device support") + amdgpu.
In that case, since the eglTerminate is missing, we end up reusing the
underlying amdgpu_device due to some caching in libdrm_amdgpu. The
latter in itself being a good solution since it allows buffer sharing
across primary and render node of the same device.
Note: we should really get this in branches all the way back to 3.30.

When a user moves their cursor the perceived behaviour is that it will
pick what is under the cursor. However this isn't how picking works.
Picking does a virtual redraw of the screen, so in some cases what gets
picked isn't the same as what the user could see on the previous frame.
It more represents what will be drawn on the next frame than what is on
screen at present.
It may be unsafe to change these semantics, and they are useful anyway.
Just document it better.

When stage views are scaled with fractional scales, the cursor rectangle
won't be aligned with the physical pixel grid, making it potentially
blurry when positioned in between physical pixels. This can be avoided
by aligning the drawn rectangle to the physical pixel grid of the stage
view the cursor is located on.

Attaching a NULL buffer should hide the cursor sprite. In these cases,
we we'll have neither surface nor buffer damage, so also update when we
just attached a NULL buffer.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/630
When 252e64a0ea moved the texture
ownership to MetaWaylandSurface, it failed to handle the case when a
NULL-buffer is attached, leaving the texture reference in place. This
caused issues when the surface should have been hidden (e.g. attaching a
NULL buffer to a cursor surface for hiding the cursor sprite).

After 4faeb12731, the maximum time allowed for an update to happen
is calculated as:
max_render_time_allowed = refresh_interval - 1000 * sync_delay;
However, extremely small refresh intervals -- that come as consequence
to extremely high refresh rates -- may fall into an odd numerical range
when refresh_interval < 1000 * sync_delay. That would give us a negative
time.
To be extra cautious about it, add another sanity check for this case.
Change suggested by Jasper St. Pierre.

The presentation timing logic (via `master_clock_get_swap_wait_time`) now
works unconditionally. By "works" we mean that a result of zero from
`master_clock_get_swap_wait_time` actually means zero now. Previously
zero could mean either a successful result of zero milliseconds or that
the backend couldn't get an answer. And a non-zero result is the same as
before.
This works even if the screen is "idle" and even if the backend doesn't
provide presentation timestamps. So now our two fallback throttling
mechanisms of relying on `CLUTTER_FEATURE_SWAP_THROTTLE` and decimating
to `clutter_get_default_frame_rate` can be deleted.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/406 and
https://bugzilla.gnome.org/show_bug.cgi?id=781835https://gitlab.gnome.org/GNOME/mutter/merge_requests/363
If `last_presentation_time` is zero (unsupported) or just very old
(system was idle) then we would like to avoid that triggering a large
number of loop interations. This will get us closer to the right answer
without iterating.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/363
That could happen if the backend did not provide presentation timestamps,
or if the screen was not changing other than the hardware cursor:
if (stage_cogl->last_presentation_time == 0||
stage_cogl->last_presentation_time < now - 150000)
{
stage_cogl->update_time = now;
return;
}
By setting `update_time` to `now`, master_clock_get_swap_wait_time()
returns 0:
gint64 now = g_source_get_time (master_clock->source);
if (min_update_time < now)
{
return 0;
}
else
{
gint64 delay_us = min_update_time - now;
return (delay_us + 999) / 1000;
}
However, zero is a value unsupported by the default master clock
due to:
if (swap_delay != 0)
return swap_delay;
All cases are now handled by extrapolating when the next presentation
time would be and calculating an appropriate update time to meet that.
We also need to add a check for `update_time == last_update_time`, which
is a situation that just became possible since we support old (or zero)
values of `last_presentation_time`. This avoids getting more than one
stage update per frame interval when input events arrive without
triggering a stage redraw (e.g. moving the hardware cursor).
https://gitlab.gnome.org/GNOME/mutter/merge_requests/363
Instead of crazy refresh rates >1MHz falling back to 60Hz, just honour
them by rendering unthrottled (same as `sync_delay < 0`). Although I
wouldn't actually expect that path to ever be needed in reality, it just
ensures an infinite `while` loop never happens.

Starting from commit 7713006f5, during X11 disposition we also unmanage the
windows using the xids hash table values list.
However, this is also populated by the X11 Meta barrier implementation and then
contains both Windows and Barriers.
So when going through the values list, check whether we're handling a window or
a barrier and based on that, unmanage or destroy it.

As per commit 7718e67f, destroying the compositor causes destroying window
actors and this leads to stack changes, but at this point the stack was already
disposed and cleared.
So, clear the stack when any component that could use it (compositor, and X11)
has already been destroyed.
As consequence, also the stamps should be destroyed at later point.

When using evdev (for Wayland), the backend receives all device events
and queue them for clutter.
Hook up the pointer accessibility handlers in clutter's main processing
queue, so that we get better accuracy for pointer location.
We need to avoid doing this on X11 though because X11 relies on the raw
events for this to work reliably, so the same is already done in the
X11 backend when using X11.

Naming the keyboard accessibility settings `a11y_settings` wrongly

For accessibility features, being either keyboard accessibility to
implement mousekeys, or pointer accessibility to implement simulated
secondary click or dwell click, we need to have a virtual device.
Add that virtual device in ClutterInputDevice so it can be used either
for keyboard or pointer accessibility.

To emulate X11 grabs, mutter as a Wayland compositor would disable its
own keyboard shortcuts and when the X11 window is an override redirect
window (which never receives focus), it also forces keyboard focus onto
that X11 O-R window so that all keyboard events are routed to the
window, just like an X11 server would.
But that's a bit of a “all-or-nothing” approach which prevents
applications that would legitimately grab the keyboard under X11 (like
virtual machine viewers) to work by default.
Change “xwayland-allow-grabs” to control whether the keyboard focus
should be locked onto override redirect windows in case of an X11 grab.
For stringent needs, careful users can still use the blacklisting
feature (i.e. a list containing “!*”) to prevent grabs from any X11
applications to affect other Wayland native applications.

The idea here is to be able to visualize and immediately
understand what is happening. Something like:
```
[ view1 ] [ view2 ]

Add the ability to add tracing instrumentation to the code. When
enabled, trace entries will generate a file with timing information
that will be processable by sysprof for generating visualization of
traces over time.
While enabled by default at compile time, it is possible to disable the
expansion of the macros completely by passing --disable-tracing to
./configure.
Tracing is so far only actually done if actually enabled on explicitly
specified threads.
This will be used by Mutter passing the write end of a pipe, where the
read end is sent to Sysprof itself via the D-Bus method 'Capture()'.
By passing that, we have to detect EPIPE that is sent when Sysprof stops
recording. Fortunately, we already ignore the signal at meta_init(), so
no need to add a custom signal handler.

Having a cursor role with a NULL renderer is valid state, and even desirable

We're currently emitting the 'grab-op-end' signal when the grab prerequisites
are met, but when display->grab_op is still set to a not-NONE value and thus
meta_display_get_grab_op() would return that in the signal callback.
And more importantly when this is emitted, devices are still grabbed.
Instead, emit this signal as soon as we've unset all the grab properties and
released the devices.

We handle this in backend specific code for x11, so do the wayland
bits here. We can only honor this on applications that request focus
on a surface after a startup request, as we do need an explicit
surface to apply the workspace on (and we don't have additional clues
like WMCLASS on X11). Notably, gtk_shell1.notify_startup doesn't suffice.
Another gotcha is that the .request_focus happens when the surface is
already "mapped". Due to the way x11 and the GDK api currently work (first
reply on the startup id, then map a window, then request focus on that
window). This means the surface will ignore at this point
window->initial_workspace, so it must be actively changed.

On a successful DnD operation we may expect the wl_data_source and
wl_data_offer to live long enough to finish the data transfer, despite the
grab operation (and other supporting data) being gone.
When that happens, the compositor expects a wl_data_offer.finish request to
notify that it finished. However the client may still chose not to send that
and destroy the wl_data_offer instead, resulting in the MetaSelectionSource
owner for the DnD selection not being unset.
When that happens, the DnD MetaSelectionSource still exists but it's
detached from any grab operation, so will not be unset if eg. the drag
source client destroys the wl_data_source. This may result in crashes when
the next drag operation tries to replace the owner DnD MetaSelectionSource.
Check explicitly for this case, in order to ensure the DnD owner is unset
after such operations.

Add debug flags based on meson's `debug` option instead of `buildtype`.

When free'ing a pipeline we destroy the BigState first and then the fragment and
vertex snippets lists using the big state pointer which is now invalid.
This causes a crash when G_SLICE=always-malloc is set and using MALLOC_CHECK_.

XLib renderer saves its data as the object cogl user data, however this data
is free'd as part of the object destruction that happens before free'ing the
renderer in _cogl_renderer_free(), from where we're calling the renderer
disconnect vfunc.
Thus in _cogl_xlib_renderer_disconnect() we happen to get an invalid pointer to
CoglXlibRenderer and we try access to it in order to close the X11 display.
This causes all the cogl tests to crash when G_SLICE=always-malloc is set and
when using MALLOC_CHECK_.
Fix this using the renderer winsys custom data instead of using cogl object data
for storing the CoglXlibRenderer, and handling the destruction of it manually.
As bonus this also makes access to the renderer data faster.

Commit df7d8e2cb highlights a crash on test_destroy_destroy, in fact it could
happen that calling clutter_actor_destroy on a child while iterating on the

So instead of manually free the children list, just ensure that this list is
valid and that when the object destruction is done, this is free'd.

This argument instructs Xwayland to exit when there are no further
client connections. However we eventually want to handle restarts
ourselves (where, notably, mutter's will be at least the last client
connection).
This behavior could also induce race conditions on startup with clients
that quickly open and close a display, which is a more pressing issue.
Also, add -noreset back (which was also removed in commit 054c25f693 that
added -terminate). We don't want to reset the X server to a pristine state
in that situation either.

It is now separated into meta_xwayland_start(), which picks an unused
display and sets up the sockets, and meta_xwayland_init_xserver(), which

lazily, currently the former calls into the latter.

In all places (including src/wayland) we tap into meta_x11_display* focus
API, which then calls meta_display* API. This relation is backwards, so
rework input focus management so it's the other way around.
We now have high-level meta_display_(un)set_input_focus functions, which
perform the backend-independent maintenance, and calls into the X11
functions where relevant. These functions are what callers should use.

We use a GtkIconTheme (thus icon-theme, thus xsettings, thus x11) just to
grab a "missing icon" icon to show in place. Relax this requirement that
surfaces for icon/mini-icon will be set, and just let it have NULL here.
It seems better to have the callers (presumably UI layers) aware of this
and set a proper icon by themselves, but AFAICS there is none in sight,
not even plain mutter seems to use MetaWindow::[mini-]icon. Probably
worth a future cleanup.

This explicit ungrab is made to ensure the other X11 display connection

This object takes care of the X11 representation of the window stack,
namely the _NET_CLIENT_LIST and _NET_CLIENT_LIST_STACKING root window

dependent on the X11 display availability. This also leaves MetaStack

We'd break the loop for moving attached windows at the first window,
meaning we'd only ever move a single attached dialogs or popup if it was
the first window in the list. This doesn't work out well when there are
multiple popups open, so don't break out of the loop at all until all
windows are potentially moved.
This fixes an issue in gtk4 where one or more non-grabbing popups would
end up unattached if there were more than one and the parent window was
moved.

XkbNewKeyboardNotify informs the client that there is a new keyboard
driving the VCK. It is essentially meant to notify that the keyboard
possibly has a different range of HW keycodes and/or a different
geometry.
But the translation of those keycodes remain the same, and we don't
do range checks or geometry checks (beyond using KEY_GRAVE as "key
under Esc", but that is hardly one). It seems we can avoid the
busywork that is releasing all our passive grabs, reloading the keymap
and regenerating the keycombos and restoring the passive grabs.

The point is to not initialize to some non-zero value to find places

If an update (new frame) had been scheduled already before
`_clutter_stage_cogl_presented` was called then that means it was
scheduled for the wrong time. Because the `last_presentation_time` has
changed since then. And using an `update_time` based on an outdated
presentation time results in scheduling frames too early, filling the
buffer queue (triple buffering or worse) and high visual latency.
So if we do receive a presentation event when an update is already
scheduled, remember to reschedule the update based on the newer
`last_presentation_time`. This way we avoid overfilling the buffer queue
and limit ourselves to double buffering for less visible lag.

There is no reason why we should have an internal type enum when we have

By providing an (internal) table to map `CoglPixelFormat`s to their
respective properties we will be able to get rid of the unusual enum

As an extra feature, we provide a `to_string()` method, which is quite
useful for debugging purposes (rather than deciphering enum values).

We're going to add some features and extra code to CoglPixelFormat, so
it's much nicer to have it in once place. Notice also that it doesn't

The `last_presentation_time` is usually a little in the past (although
sometimes in the future depending on the driver). When it's over 2ms
(`sync_delay`) in the past that would trigger the while loop to count up so
that the next `update_time` is in the future.
The problem with that is for common values of `last_presentation_time`
which are only a few milliseconds ago, incrementing `update_time` by
`refresh_interval` also means counting past the next physical frame that
we haven't rendered yet. And so mutter would skip that frame.
**Example**
Given:
```
last_presentation_time = now - 3ms
sync_delay = 2ms
refresh_interval = 16ms
next_presentation_time = last_presentation_time + refresh_interval
= now + 13ms
-3ms now +13ms +29ms +45ms
----|--+------------|---------------|---------------|----
: :
last_presentation_time next_presentation_time
```
Old algorithm:
```
update_time = last_presentation_time + sync_delay
= now - 1ms
while (update_time < now)
(now - 1ms < now)
update_time = now - 1ms + 16ms
update_time = now + 15ms
next_presentation_time = now + 13ms
available_render_time = next_presentation_time - max(now, update_time)
= (now + 13ms) - (now + 15ms)
= -2ms so the next frame will be skipped.
-3ms now +13ms +29ms +45ms
----|--+------------|-+-------------|---------------|----
: : :
: : update_time (too late)
: :
last_presentation_time next_presentation_time (a missed frame)
```
New algorithm:
```
min_render_time_allowed = refresh_interval / 2
= 8ms
max_render_time_allowed = refresh_interval - sync_delay
= 14ms
target_presentation_time = last_presentation_time + refresh_interval
= now - 3ms + 16ms
= now + 13ms

The reason nobody noticed these missed frames very often was because
mutter has some accidental workarounds built-in:
* Prior to 3.32, the offending code was only reachable in Xorg sessions.
It was never reached in Wayland sessions because it hadn't been
implemented yet (till e9e4b2b72).
* Even though Wayland support is now implemented the native backend
provides a `last_presentation_time` much faster than Xorg sessions
(being in the same process) and so is less likely to spuriously enter
the while loop to miss a frame.
* For Xorg sessions we are accidentally triple buffering (#334). This
is a good way to avoid the missed frames, but is also an accident.
* `sync_delay` is presently just high enough (2ms by coincidence is very
close to common values of `now - last_presentation_time`) to push the
`update_time` into the future in some cases, which avoids entering the
while loop. This is why the same missed frames problem was also noticed
when experimenting with `sync_delay = 0`.

Linux glibc supports a malloc implementation that is allows to be tunable using
environment variables, to check allocation issues.
When MALLOC_CHECK_ is set to 3, a diagnostic message is printed on stderr and
the program is aborted.
Setting the MALLOC_PERTURB_ environment variable causes the malloc functions in
to return memory which has been wiped and initialized with the byte value of the
environment variable.
So use this features when running tests in order to catch better memory errors.

All child classes of `MetaWaylandShellSurface` as well as
`MetaWaylandSurfaceRoleXWayland` should only sync their actor if
their toplevel surface has a window. Currently this check is done
in the actor-surface class, but not all surface classes have a
toplevel window, e.g. dnd-surfaces.
Move the check to the right places.
For subsurfaces this assumes that the subsurface is not the child of
a window-less surface (like, as stated above, e.g. a dnd-surface).
If we want to support subsurfaces of window-less surfaces in the future
we have to extend the check here.
But as this is not a regression, ignore this case for now.

If we update the ready time while the source is already in the

the source will still be dispatched. This could cause incorrect idle
watch firing causing the power management plugin in
gnome-settings-daemon to sometimes turn off monitors due to it believing
the user had been idle for some time, while in fact, they just logged
back in.

Cogl unit tests are just functions inside normal code files that needs to be
dload'ed by the test binary.
So in case unit-tests are enabled, we need to export those symbols.
Since map file can't be overridden, use a configure_file to generate the map

This is a simple clipboard manager implementation on top of MetaSelection.
It will inspect the clipboard content for UTF-8 text and image data whenever
any other selection source claims ownership, and claim it for itself
whenever the clipboard goes unowned.
The stored text has a maximum size of 4MB and images 200MB, to prevent the
compositor from allocating indefinite amounts of memory.
This is not quite a X11 clipboard manager, but also works there.

This object represents a Wayland selection owner. In order to invert the
FD direction (we hand an output fd, but want an inpu fd), create an

This object represents the selection ownership from an X11 client. The
list of supported targets is queried upfront, so its initialization is
asynchronous. Requests to read contents from the selection will hand

MetaSelectionSource represents a primary/clipboard/dnd selection owner,
it is an abstract type so wayland/x11/etc implementations can be provided.
These 3 selections are managed by the MetaSelection object, the current
selection owners will be set there, and signals will be emitted so the
previous selection owner can clean itself up.
The actual data transfer is done through the meta_selection_transfer_async()
call, which will take a GOutputStream and create a corresponding
GInputStream from the MetaSelectionSource in order to splice them.

When the compositor is destroyed we should cleanup the list of window actors we
created and destroy them.
Since all the actors are added to the window_group or top_window_group we can
just destroy these containers (together with the feedback_group), and simply
free the windows list.
This is particularly needed under X11 because before we destroy the display, we
might do some cleanups as detaching the surface pixmaps and freeing the damages
and if this happens at later point (for example when triggered by garbage
collector in gnome-shell), we might crash because the x11 dpy reference is
already gone.
Destroying the window actors instead, ensures we avoid any further call to X11
related functions and that we release the actors XServer resources.

Clutter does the nicety of connecting just created PangoContexts to
ClutterBackend signals in order to update it on resolution/font changes.
However the way the signals are disconnected (automatically via
g_signal_connect_object() auto-disconnect feature) may incur into
performance issues with a high enough number of ClutterActors with a
PangoContext (eg. ClutterText) as the lookup by closure is linear across
all signals and handlers.
Keep the handler IDs around, and disconnect them specifically on dispose
so it is more O(1)-ish.

When an application stops responding, the shell darkens its windows.
If a window from a not-responding application gets unmanaged
then the shell will currently throw an exception trying to retrieve

That leads to a "stuck window" ghost on screen and a traceback
in the log.
This commit addresses the problem by making sure the effect is cleaned
up before the actor is disocciated from its window.

mousekeys work only when NumLock is OFF:

disable mousekeys when NumLock in ON so that switching NumLock ON

When focus stealing prevention kicks in, mutter would set the demand
attention flag on the window.
Focus stealing prevention would also prevent the window from being
raised and focused, which is expected as its precisely its purpose.
Yet, when that occurs, the user expects the window which has just been
prevented from being focused to be the next one in the MRU list, so
that pressing [Alt]-[Tab] would raise and give focus to that window.
This works fine when the window is placed on the primary monitor, but
not when placed on another monitor, in which case the window which has
been denied focus is placed ahead of the MRU list and pressing
[Alt]-[Tab] would leave the focus on the current window.
This is because of a mechanism in `meta_display_get_tab_list()` which
forces the windows with the demand attention flag set to be placed first
in the MRU list when they're placed on a workspace different from the
current one.
But because workspaces apply only to the primary monitor (by default),
the windows placed on other outputs have their workspace set to `NULL`
which forces them ahead of the MRU list by mistake.
Fix this by using the appropriate `meta_window_located_on_workspace()
function to check if the window is on another workspace.

If a second `set_{sync,complete}_pending` was queued before the idle
handler had flushed the first then one of them would be forgotten.
It would stay queued forever and never emitted as a notification.
This could happen repeatedly causing a slow leak. But worse still,
`clutter-stage-cogl` would then have `pending_swaps` permanently stuck
above zero preventing the presentation timing logic from being used.
The problem is that a boolean can only count to one, but in some cases
(triple buffering, whether intentional or accidental #334) we need it to
count to two. So just change booleans to integers and count properly.

The keyboard accessibility setting "enable" is actually even more
misleading that initially anticipated, as it does not control the
entire keyboard accessibility feature, but just the "enable by
keyboard" feature, i.e. being able to enable or disable stickykeys
or slowkeys using various keyboard actions.
Yet the accessibility features should still work even if the "enable"
setting is unset, those can be controlled by the accessibility menu in
GNOME Shell for example.
Change the clutter/evdev implementation to match that behavior as found
in the x11 backend, so both backends are now consistent.

Since "renderer/native: make EGL initialization failure not fatal" it is
possible, under specific failure conditions, to end up with a primary GPU whose
EGL initialization failed. That cannot work.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/521
The failure to initialize EGL does not necessarily mean the KMS device cannot
be used. The device could still be used as a "secondary GPU" with the CPU copy
mode.
If meta_renderer_native_create_renderer_gpu_data () fails,
meta_renderer_native_get_gpu_data () will return NULL, which may cause crashes.
This patch removes most of the failures, but does not fix the NULL dereferences
that will still happen if creating gpu data fails.
This patch reorders create_renderer_gpu_data_gbm () so that it fails hard only
if GBM device cannot be created, and otherwise always returns an initialized
gpu data structure. Users of the gpu data structure are responsible for
checking egl_display validity.
The GBM device creation failure is a hard failure because presumably GBM is
necessary for cursors.

We're currently always waiting for unfinished page flips before flipping
again. This is awkward when we are in an asynchronous retry-page-flip
loop, as we can synchronously wait for any KMS page flip event.
To avoid ending up with such situations, just freeze the frame clock
while we're retrying, then thaw it when we succeded.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/506
We rely on the frame clock to compress input events, thus if the frame
clock stops, input events are not dispatched. At the same time, there
is no reason to redraw at a full frame rate, as nothing will be
presented anyway, so slow down to 10Hz (compared to the most common
60Hz). Note that we'll only actually reach 10Hz if there is an active
animation being displayed, which won't happen e.g. if there is a screen
shield in the way.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/506
When we're in a page-flip retry loop due to the FIFO being full
(drmModePageFlip() failing with EBUSY), we should not continue to try
when starting to power save, as that means we're blocking new frames,
which itself blocks input events due to them being compressed using the
frame clock.
We'd also hit an assert assuming we only try to page flip when not power
saving.
Thus, fake we flipped if we ended up reaching a power saving state while
retrying.

DPMS is configured from a bit all over the place: via D-Bus, via X11 and

differently, directly poking at the field in MetaMonitorManager.

In a multi-monitor setup there is a separate paint run for each monitor.
If an actor doesn't intersect the first monitor painted then it is culled
out for that monitor to save time. Unfortunately this would mean
`clutter_actor_paint` was setting `is_dirty = FALSE` before the actor had
yet been painted on any monitor.
This meant that effects like `ClutterOffscreenEffect` were not receiving
the flag `CLUTTER_EFFECT_PAINT_ACTOR_DIRTY` when they should have, and
so would rightfully think they don't need to do a full internal
invalidation. So `ClutterOffscreenEffect`, and probably other effects,
did not repaint correctly unless on the first monitor in the list.
The fix is to simply avoid setting `is_dirty = FALSE` on those paint
runs where the actor has been culled out (`clutter_actor_continue_paint`
wasn't called). It is only safe to clear the flag after
`clutter_actor_continue_paint` has been called at least once per stage
paint.

Commit 8e9184b6 added filtering to avoid image jaggies when downscaling
but used `LINEAR_MIPMAP_NEAREST`. In some situations this could lead to
GL choosing a single lower resolution mipmap and then upscaling it, hence
slightly blurry.
We don't want to revert that change since it avoids aliasing jaggies, so
let's use `LINEAR_MIPMAP_LINEAR` instead. This provides the highest quality
filtering that GL can do and avoids the situation of GL using a single
mipmap that's lower resolution than the screen. Now it will blend that one
with the next mipmap which is higher resolution than the screen. This still
avoids jaggies but also maintains 1px resolution.

Enabling keyboard accessibility features on Wayland from the keyboard

call g_signal_handler_disconnect instead g_cancellable_disconnect if this is the
case.

Splitting out the X11 display initialization from display_open() broke
restoring the previously active workspace in two ways:
- when dynamic workspaces are used, the old workspaces haven't
been restored yet, so we stay on the first workspace
- when static workspaces are used, the code tries to access
the compositor that hasn't been initialized yet, resulting
in a segfault
Fix both those issues by splitting out restoring of the active workspace.

We use the input_method on both branches, but only check for its existence
when enabling the text_input. The case of focusing out shouldn't happen in
practice as we couldn't have focused in ever before, but still make the
check one level above so it's clearer that the text_input's IM focus cannot
be enabled without an IM implementation.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/432
Enable the OSK if receiving .enable consecutively (i.e. the
ClutterInputFocus was already focused). We specifically want to avoid
enabling the panel just because of focus changes within a surface (where
the .disable request across focus change would previously unfocus the
ClutterInputFocus). Prior state should be preserved if possible in that
situation.

The ClutterVirtualInputDevice API was fixed to use Clutter button

Since e3e933c4 a keyval can be temporarily remapped to an unused keycode. Due to
some limitations in XTestFakeKeyEvent, the remapping has to be done in the first
xkb group/layout. In case there are two or more keyboard layouts enabled and the
selected keyboard layout is not the first, clutter_keymap_x11_keycode_for_keyval
will fail to retrieve the correct keycode for a remapped keyval. Let's use the
reserved_keycodes map in order to retrieve the correct keycode if needed.

Meta rectangles are integer based while clutter works in floating coordinates,
so when converting to integers we need a strategy.
Implement the shrink strategy by ceiling the coordinates and flooring the width,
and the grow strategy reusing clutter facility for this.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/3
The clamped rectangle currently could not fully contain the original fractional
rectangle because it doesn't take care of the fact that the new width should
consider the fact that flooring we'd translate the rectangle, and thus to cover
the same area we need to take care of it.
So, to properly compute the width and height, calculate x2 and y2 first and then
use this ceiled value to compute the actual width using the floored x1 and y1.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/3
When we try to update the FB, we might face the case in which the effect target
framebuffer does not need any redraw, because it's already properly sized and
scaled, but the filter applied to the pipeline is not, because it has been
computed for a non-fractional scaling.
This is happens for example to clutter actors with a flattening effect (i.e.
override redirect mode set), that might have been generated properly for a
celied scaling level, but when we go fractional we need to ensure to use a
linear filter, as the 1:1 texel:pixel assumption is not true anymore.
https://bugzilla.gnome.org/show_bug.cgi?id=765011https://gitlab.gnome.org/GNOME/mutter/merge_requests/3
At this level we use ceiled resource-scale when painting fractional value
When using fractional scaling we still need to create an integer-sized
texture and then we should paint it using a size which is proportional
to the real actor size ratio, and only paint a subsample of it, but this
doesn't seem to work properly with some weird scaling values.
Then, it's just better to draw the texture ceiled and then we scale it
down to match the proper actor scaling at paint level.
https://bugzilla.gnome.org/show_bug.cgi?id=765011https://gitlab.gnome.org/GNOME/mutter/merge_requests/3
When resource scale is set we need to generate a scaled PangoLayout (by adding
a new scale attribute, or adjusting the one we already have according the
resource scale), then it has to be painted with proper scaling matrix.
So everything that has to do with PangoLayout has to be in real coordinates,
then clutter logical coords multiplied by resource scaling.
While the actual size of the layout is the one of the PangoLayout divided by
resource scale.
We map the text positions to logical coords by default, while using
the pixel coordinates when painting.
We fall back to scale 1 when calculating preferred size if no scale is
known. The pango layout will not have set a layout scale attribute,
meaning it'll be 1, thus we should just assume the layout scale is 1 here.
Not doing so might result in the preferred size being 0x0 meaning the
actor won't be laid out properly.

A clutter actor might be painted on a stage view with a view scale
other than 1. In this case, to show the content in full resolution, the
actor must use a higher resolution resource (e.g. texture), which will
be down scaled to the stage coordinate space, then scaled up again to
the stage view framebuffer scale.
Use a 'resource-scale' property to save information and notify when it
changes.
The resource scale is the ceiled value of the highest stage view scale a
actor is visible on. The value is ceiled because using a higher
resolution resource consistently results in better output quality. One
reason for this is that rendering is often not perfectly pixel aligned,
meaning even if we load a resource with a suitable size, due to us still
scaling ever so slightly, the quality is affected. Using a higher
resolution resource avoids this problem.
For situations inside clutter where the actual maximum view scale is
needed, a function _clutter_actor_get_real_resource_scale() is provided,
which returns the non-ceiled value.
Make sure we ignore resource scale computation requests during size
requests or allocation while ensure we've proper resource-scale on
pre-paint.
https://bugzilla.gnome.org/show_bug.cgi?id=765011https://gitlab.gnome.org/GNOME/mutter/merge_requests/3
We need to use pixel size of the monitor in order to generate a valid
texture with full quality for current monitor
In spanned case the background should cover all the differently scaled monitors
thus we scale the texture up to the maximum scaling level and then we resample
it drawing only each side in the monitor it should occupy using the proper
scaling level.
In wallpaper mode (or color mode) for example we don't need to scale the area,
also the texture size we return should be unscaled, not to confuse
MetaBackgroundActor making it use more space than needed.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
When we floor the quad coordinates then we've also to enlarge the quad by the
difference between the floored value and the actual coordinate, otherwise

When the touch_down event was not delivered to Wayland clients, there's
no point in keeping the touchpoint in our list, so remove it early
inside update() instead of removing it after the touch ended.
This fixes a crash inside touch_handle_surface_destroy() where the
assertion to make sure the surface is removed fails because the
touch_count of the surface never reached 0. This in turn happened
because a new sequence was added, while a (already ended one) wasn't
removed from the touch->touches list before. This caused the touch
counter to get incremented by 1 while no new sequence was added to the
list (because Clutter reuses sequence IDs, the old sequence is equal to
the new one, i.e. the new sequence already is present in the list).

Make the RecordWindow method also understand the 'cursor-mode' property.
For 'embedded' the cursor is drawn onto the pixel buffer using cairo,
otherwise it works similarly to how RecordMonitor deals with it.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/413
To be used to translate absolute cursor positions to relative positions,
as well as to determine whether a cursor sprite is inside the stream or
not. It also helps calculating the scale the cursor sprite needs to be
scaled with to be in stream coordinate space.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/413
As the stream size is the logical monitor size multiplied with the ceil
of the logical monitor scale, the corresponding logical size, which is
what should be passed via the size property on the D-Bus object, should
be the logical monitor size.

Make the monitor implementation do things strictly related to its own
source type, leaving the Spa related logic and cursor read back in the

This is an ABI break, hopefully an unimportant one since this signal/vmethod
is barely overridden.
The signal has been added an extra ClutterPaintVolume argument, and has been
given a boolean return value. The recursion to the parents has been taken
out of the default implementation and into the caller, using the returned
boolean parameter to control further propagation.
Passing the ClutterPaintVolume is easier on performance, as we don't need
setting this pointer as gobject data just to retrieve/unset it further
in propagation.

Since commit 8df2a1452c (As pointed out by Robert Mader) we just happened
do this check when doing the first lookup for a Wayland surface for a
XWayland window, when we are later notifying upon surface creation we just
set the relation with no further checks.
The cases pointed out in the comment (eg. window changing decoration) might
presumably happen in a quick enough sequence that we have two scheduled
associations on the fly, so move this check to the more generic
meta_xwayland_associate_window_with_surface() which is called on both
immediate and delayed paths.

XWayland creates buffers of the combined size of all connected displays.
This can, especially on older but still in use hardware, exceed the limits

We might fail to page flip a new buffer, often after resuming, due to
the FIFO being full. Prior to this commit, we handled this by switching
over to plain mode setting instead of page flipping. This is bad because
we won't be synchronized to the refresh rate anymore, but just the
clock.
Instead, deal with this by trying again until the FIFO is no longer
full. Do this on a v-sync based interval, until it works.
This also changes the error handling code for drivers not supporting
page flipping to rely on them returning -EINVAL. The handling is moved
from pretending a page flip working to explicit mode setting in
meta-renderer-native.c.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/460
A renderer view will, under the native backend, since long ago always

https://gitlab.gnome.org/GNOME/mutter/issues/460
Prior to this commit, MetaWaylandSurface held a reference to
MetaWaylandBuffer, who owned the texture drawn by the surface. When
switching buffer, the texture change with it.
This is problematic when dealing with SHM buffer damage management, as
when having one texture per buffer, damaged regions uploaded to one,
will not follow along to the next one attached. It also wasted GPU
memory as there would be one texture per buffer, instead of one one
texture per surface.
Instead, move the texture ownership to MetaWaylandSurface, and have the
SHM buffer damage management update the surface texture. This ensures
damage is processed properly, and that we won't end up with stale
texture content when doing partial texture uploads. If the same SHM
buffer is attached to multiple surfaces, each surface will get their own
copy, and damage is tracked and uploaded separately.
Non-SHM types of buffers still has their own texture reference, as the
texture is just a representation of the GPU memory associated with the
buffer. When such a buffer is attached to a surface, instead the surface
just gets a reference to that texture, instead of a separately allocated
one.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/199
When we freed the cursor GPU state including the gbm_bo objects attached
to it, we didn't unset the cursor renderer private of the CRTCs of the
associated GPU. This means that HW cursor invalidation could potentially
break if a new gbm_bo happened to be allocated at the same memory
address as the previous one.
To avoid this, iterate through the CRTCs of the GPU of which the cursor
data is freed, and unset the cursor renderer private if it was the one
destroyed.

What was actually done when calling meta_wayland_buffer_attach() was

The signal handler must return TRUE as the invocation is already handled

We should not only take the old CRTC for an output whenever
possible, but we should also assign one that is 'free', i.e.
one that another monitor (to be processed after this one)
isn't using, so that that monitor can use the same CRTC.
https://gitlab.gnome.org/GNOME/mutter/issues/373
We shouldn't change an output's CRTC if we don't have to, as
that causes the output to go black.
This patch depends on
"monitor-unit-tests: initial crtcs in custom_lid_switch".
https://gitlab.gnome.org/GNOME/mutter/issues/373
This test forgot to specify the existing CRTC routings in the setup. For the
first output the default 0 was ok, now it is -1 to ensure that the code will
assign it correctly. For the second output the default 0 was incorrect, because
possible_crtcs does not include 0. Now that CRTC is initialized to off
instead, because the second output is hotplugged later and running a CRTC
without an output does not make sense.
This fix will keep this test passing when a future patch attempts to preserve
existing CRTC routings. Assuming that any existing routing is valid, such
routing will be kept. In this test case the existing routing was illegal, it
should have been impossible, which then causes that future patch to fail the
test by assigning the wrong CRTC.

The external grab handler is shared across all external bindings and external
bindings have now different binding flags. For this reason, when rebuilding the

in MetaKeyGrab too and use this when rebuilding the binding table to avoid the

This basically reverts commit 54735dec, which tried to avoid the

On X11, if a window cannot be maximized because its minimum size is
already larger than the output size, a request to maximize will be
ignored.
On Wayland, however, we would still honor the maximize request and
switch the window state to maximized, without actually moving the window
which leads to weird visual effects, as the window end up being
maximized in-place.
To avoid this, make sure the window has the maximize functionality
available prior to change its state in xdg-shell `set_maximized`
request.

This adds a pipeline stage for merge requests that checks that the
commit message contains an URL to either a issue or a merge request.
This means that for merge requests without corresponding issues will

merge requests without URLs.

As per commit 43633d6b, we mark an unmanaging window as not focusable, while

Also this wouldn't allow to check if a window can be focused when unmanaging it,
so let's revert the previous behavior.

This adds the required bits to wayland surfaces and ties them up
to the compositor parts.
It is based on and very similar in nature to buffer transforms.
From the specification:
> The global interface exposing surface cropping and scaling
> capabilities is used to instantiate an interface extension for a
> wl_surface object. This extended interface will then allow cropping
> and scaling the surface contents, effectively disconnecting the
> direct relationship between the buffer and the surface size.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/323
This implements the viewporter protocol which offers a cropping and scaling
capabilities to wayland clients.
There are several use cases for this, for example video players and games,
both as a convenience function and as potential performance optimization when
paired with hardware overlays etc.

Until meson 0.50, setting the install parameter in 'configure_file' is ignored
if 'install_dir' is set. Then until mutter doesn't depend on such meson version
cogl_installed_tests_libexecdir should be empty unless have_installed_tests is
false, or this file will be installed anyway.

For various error and warning messages, mutter includes a description of
the window, and that description includes a snippet of the title of the
window. Those snippets find their way into system logs, which then means
they can potentially find their way into bug reports and similar. Remove
the window title information to eliminate this potential privacy issue.
Unfortunately, many parts of GNOME Shell and Mutter and Clutter
still use the implicit Cogl1 API. As such, it as a transition
between the old and new APIs, it is important to keep the
implicit draw framebuffer updated.
ClutterRootNode does not keep it updated though, and it might
lead to problems when rendering offscreen textures.
Fix that by pushing and popping the root node framebuffer on
pre- and post-draw, respectively.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/405
The ClutterRootNode paint node is theoretically the
top-most node of a paint nodes tree, except that we
are not in the point of having full rendering trees
in Clutter (all rendering performed by paint nodes
is still local and immediate).
When controlling the rendering tree, MetaShapedTexture
may need to paint into an offscreen framebuffer under
some circumstations.
Expose ClutterRootNode so that MetaShapedTexture can
use it to render to offscreen framebuffers.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/405
When painting to an offscreen framebuffer, MetaShapedTexture will
need to have full control of the painting routines of paint nodes.
As such, expose clutter_paint_node_paint() to allow forcing a
paint nodes paint from MetaShapedTexture.

The multitexture API is not a shortcut for multiple calls
to the single texture API. It is meant to wrap calls to

ClutterImage is a ClutterContent implementation that
has an internally managed CoglTexture. This texture
is recreated when new image data is set.
ClutterContent implementations may have control over
the allocation of the widgets they're attached to,
through CLUTTER_REQUEST_CONTENT_SIZE. On those cases,
if the new image data differs in size from the previous
data, it is important to notify those actors about the
size change. However, currently ClutterImage does not
notify them.
With the introduction of clutter_content_invalidate_size(),
it is possible to report the size changes to attached
actors.
Adapt ClutterImage to invalidate_size() when image data
has different sizes.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/405
ClutterContent has the ability to dictate the layout of any
given actor, through the CLUTTER_REQUEST_CONTENT_SIZE request
mode.
However, there is no way for ClutterContent implementations

clutter_content_invalidate_size().

If the GPU copy path would use a software renderer, fall back to the CPU
copy path. The CPU copy path is possibly faster and avoids screen

Print the pixel format chosen for an output on a secondary GPU for
debugging. Knowing the format can aid in debugging e.g. red/blue channel
swaps and CPU copy performance issues.
This adds a DRM format printing helper in meta-crtc-kms.h. This header
is included in most native backend files making it widely available,
while DRM formats are specific to the native backend. It could be shared
with Wayland bits, DRM format codes are used there too.
The helper makes the pixel format much more readable than a "%x".
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
When setting up an output on a secondary GPU with the CPU copy mode,
allocate the dumb buffers with a DRM format that is advertised supported
instead of hardcoding a format.
Particularly, DisplayLink devices do not quite yet support the hardcoded
DRM_FORMAT_XBGR8888. The proprietary driver stack actually ignores the
format assuming it is DRM_FORMAT_XRGB8888 which results the display
having red and blue channels swapped. This patch fixes the color swap
right now, while taking advantage if the driver adds support for XBGR
later.
The preferred_formats ordering is somewhat arbitrary. Here it is written
from glReadPixels point of view, based on my benchmarks on Intel Haswell
Desktop machine. This ordering prefers the format that was hardcoded
before.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
These functions allow inspecting which pixel formats a CRTC's primary
plane supports. Future patches will inspect the supported formats and
pick a framebuffer format accordingly instead of hardcoding a format.
The copy list function will be used to initialize a formats list, and
the supports format function will be used to intersect that list against
another CRTC's supported formats.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
This avoids having to hardcode the same fallbacks elsewhere multiple
times when determining what formats might be suitable for a set of
CRTCs. The formats_modifiers hash table is now guaranteed to be
populated with at least something, so future code will not need to
handle it being empty.
The hardcoded fallback formats are a minimal set probably supported by
most hardware. XRGB8888 is the format that, according to ancient lore,
all DRM devices should support, especially if they don't have the
capability to advertise otherwise. Mutter also hardcodes XRGB8888 as the
GBM surface format, so it is already required on primary GPUs.
XBGR8888 matches the most common OpenGL format, sans alpha channel since
scanout hardware has not traditionally supported alpha. XBGR8888 is here
also because Mutter hardcodes that format for secondary GPU outputs when
using the CPU copy path.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
If the IN_FORMATS property is not found, copy the formats from the DRM
plane instead. This is the fallback for getting a list of formats the
primary plane supports when DRM universal planes capability is enabled.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
Rather than picking just one format, parse and store all the formats and
their modifiers.
This gives us a list of supported formats (and modifiers) on a CRTC
primary plane. Later I will be using this list to choose a framebuffer
format instead of hardcoding it.

When profiling gnome-shell it was found that one of the main triggers
of `clutter_actor_queue_relayout` during animations was
`clutter_actor_set_margin_internal` continuously setting the same

avoid redundant margin changes.
This helps to further improve performance in:

This change previously landed as 59acb3895 and then got reverted because
it was found to make gnome-shell#517 worse. However that bug now has a
proper fix and this branch isn't really directly related so is being
reproposed...
Just move the minimal bits to this ClutterKeymapEvdev object. Much
of the functionality of a keymap is spread along ClutterSeatEvdev,
ClutterDeviceManagerEvdev and ClutterVirtualInputDevice. Future
refactors are due here.
Also, ideally keymaps are per-seat objects (at least keyboard state
is). We don't expose much info about seats altogether outside the
evdev device manager implementation. We just poke the main seat at
places, but eventually seats should be public.
We thus far have similar objects/code internal to backends. Expose the
minimum API necessary to cater for gnome-shell as a generic object.
So far only the X11 backend has an actual GObject for it, and was made
to be a subclass right away.
`distribute_natural_allocation` expects an input >= 0 of type `gint`. In
`get_preferred_size_for_opposite_orientation` it is used with an unchecked
variable `size` of type `gfloat`, which in case it is `Infinity`, gets
passed on in the macro `MAX (0, size)`. `Infinity` becomes `G_MININT`
when implicitly casted to `gint` in `distribute_natural_allocation`,
triggering the assertion `extra_space >= 0`.
The resulting warning in the log is counter intuitive and not very
helpful.
Use `float` in `distribute_natural_allocation` instead of `gint` and
assert on denormal values so we can more easily identify bugs.
Additionally change some types while at it and add a even more
expressive warning referencing the actor at one point.

This is done through gtk-shell ATM. If a window requests focus with
an invalid startup ID, just the demands-attention flag will be set.
The "did user interaction happen in between" checks are left to
meta_window_activate_full/meta_window_focus, by passing the timestamp
of the original launch request.
This version has 2 new requests:
- gtk_shell1.notify_launch notifies the compositor that the requesting
client shall launch another application. The given ID is expected to
be unique.
- gtk_surface1.request_focus notifies the compositor that a surface
requests focus due to it being activated. The given ID is passed to
this process through undetermined means, if it corresponds with a
current startup ID and there was no user interaction in between the

It scaled the logical monitor rect with scale to get the stream
dimensions, but that is only valid when having
'scale-monitor-framebuffers' enabled. Even when it was, it didn't work
properly, as clutter_stage_capture_into() doesn't work properly with
scaled monitor framebuffers yet.

Commit 25f416c13d added additional compilation warnings, including
-Werror=return-type. There are several places where this results
in build failures if `g_assert_not_reached()` is disabled at compile

`ClutterOffscreenEffect` had been getting the wrong bounding box in the
case of clones and descendents of clones, causing visibly incorrect
clipping. This was due to `clutter_actor_get_paint_box` only ever being
given the source actor during a paint (which is correct) and not the clone.
Even if we weren't painting a clone but an offscreened descendent of a
clone (like in gnome-shell's desktop zoom), we would get the wrong result.
Fortunately we don't need to know the actual clone/actor being painted so
don't need to call the problematic `clutter_actor_get_paint_box` at all.
The solution is to only keep untransformed rendering in the FBO and leave
the correct transformation for later. The correct clone/actor's
transformation is already set for us as the current cogl modelview matrix
by `clutter_actor_paint`.
Bonus optimization: This all means we don't need to keep `last_matrix_drawn`
or force a full repaint every time some part of the transformation changes.
Because the FBO contents are no longer affected by transformations. As it
should be. In other words, offscreen-effected actors can now move around
on screen without themselves being repainted.
Special thanks to Mai Lavelle for identifying the cause of the problem.

Shell is using these, which was revealed by
1bbb5c8107 breaking its build when
generating its introspection due to meta_startup_notification_get_type()
not being found.
We keep the class structs private, so in practice MetaStartupSequence
and MetaBackend can't be derived from (the are semi-private).
Make meson link libmutter using -fvisibility=hidden, and introduce META_EXPORT
and META_EXPORT_TEST defines to mark a symbols as visible.
The TEST version is meant to be used to flag symbols that are only used
internally by mutter tests, but that should not be considered public API.
This allows us to be more precise in selecting what is exported and what is
not, without the need of a version-script file that would be more complicated
to maintain.

MonitorManager was inheriting from MetaDBusDisplayConfigSkeleton, this was
causing introspection to see this like a GDBus skeleton object exposing to
clients methods that were not required.
Also, this required us to export meta_dbus_* symbols to the library, while
these should be actually private.
So, make MetaMonitorManager to be just a simple GObject holding a skeleton
instance, and connect to its signals reusing most of the code with just few
minor changes.

pkg-config files for mutter are generated using *_pkg_deps as requires, but
programs linked with libmutter doesn't need most of these private dependencies
which are only needed for building and linking mutter and its subprojects.
So list packages needed only by mutter itself inside *_pkg_private_deps and
don't expose such packages to pkg-config, but only use them at build time.

Clutter exports symbols explicitly using `CLUTTER_EXPORT`, so everything should

Some types were declared in the public headers so that g-ir-scanner
could resolve the types. This caused warnings when using
-Wredundant-decls, so only redeclare them for the gir scanner.
As with the commits earlier, this also adds const qualifiers where
expected. However, the const variables are casted to non-const variants
so they can be passed to glib functions that take non-const variants but
expect const-like input.
In plenty of places a non-static function was defined but didn't have
the corresponding declaration. Fix this by adding them, or alternatively
making them static.
cogl-path uses types from glu.h, but to avoid a build dependency on glu,
it kept a minified copy of glu.h in tree. Drop this file and just use
the actual glu.h. To avoid linking to libGLU.so, just use the
includepath, instead of actually adding glu as a real dependency.
This means we can remove an includepath meant to make it possible to
include <GL/glu.h>.
gluTessCallback() expects an equivalent to a GFunc, but we pass
functions with arguments without casting. To get rid of warnings, cast
the callback function pointer to the expected type.
The const qualifiers were implicitly discarded here and there. Avoid that
either by adding the constness, or casting it away when a const variable
is passed to a function that is defined as non-const but effectively
expect a const.
Previously, the clipping rectangle passed to
`meta_surface_actor_get_image()` was updated with the actual texture
size, but recent changes in `meta_shaped_texture_get_image()` now keep
the caller's clipping rectangle unchanged.
The implementation of `meta_window_actor_capture_into()` was relying on
the old behavior of updating the passed clipping rectangle, but now that
it's kept unchanged, the actual clipping rectangle used to copy the data
is wrong, which causes either a distorded image or worse, a crash of
mutter.
Use the resulting cairo image size to copy the data instead of the
clipping rectangle to avoid the issue and get the expected size.

This is a GAppLaunchContext subclass meant to replace usage of
GdkAppLaunchContext in gnome-shell.
Launch contexts get created from the MetaStartupNotification as
they are closely related. The messaging underneath depends on
the availability of a X11 display, if there is one we go through
it (and libsn). If there is none, we still create startup sequences
manually for wayland clients.
A NULL argument is expected here in order to unset the selection,
meta_wayland_data_device_set_primary() accepts a NULL source, but
gtk_primary_selection_device.set_selection was not handling a
NULL wl_resource.

The 'cursor-mode', which currently is limited to RecordMonitor(), allows
the user to either do screen casts where the cursor is hidden, embedded
in the framebuffer, or sent as PipeWire stream metadata.
The latter allows the user to get cursor updates sent, including the
cursor sprite, without requiring a stage paint each frame. Currently
this is done by using the cursor sprite texture, and either reading
directly from, or drawing to an offscreen framebuffer which is read from
instead, in case the texture is scaled.

There may be reasons to temporarly inhibit the HW cursor under certain

To get a consistent behaviour no matter whether HW cursors are in use or
not, make sure to copy the framebuffer content before the stage overlays
(cursor sprite textures) are painted.

Mutter prefers platform devices over anything else as the primary GPU.
This will not work too well, when a platform device does not actually
have a rendering GPU but is a display-only device. An example of this
are DisplayLink devices with the proprietary driver stack, which exposes
a DRM KMS platform device but without any rendering driver.
Mutter cannot rely on EGL init failing on such devices either, because
nowadays Mesa supports software renderers on GBM, so the initialization
may well succeed.
The hardware rendering capability is recognized by matching the GL
renderer string to the known Mesa software renderers. At this time,
there is no better alternative to detecting this.
The secondary GPU data is abused for the GL renderer, as the Cogl
context may not have been created yet. Also, the Cogl context would
only be created on the primary GPU, but at this point the primary GPU
has not been chosen yet. Hence, GPU copy path GL context is used as a
proxy and predictor of what the Cogl context might be if it was created.
Mind, that even the GL flavour are not the same between Cogl and
secondary contexts, so this is stretch but it should be just enough.
The logic to choose the primary GPU is changed to always prefer hardware
rendering devices while also maintaining the old order of preferring
platform over boot_vga devices.

create_renderer_gpu_data_egl_device () relied on the primary GPU being
already chosen for the "EGLDevice currently only works with single GPU
systems" error message. A future patch will choose the primary GPU after
this, not before, so this check needs to be rewritten before the
initialization order is changed.
The new check is implemented exactly as the error message says: there
must be exactly one GPU, otherwise fail.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/271
Make the choosing and identity of the primary GPU an internal detail to
the native renderer. MonitorManagerKms did not need it for anything.
The primary GPU logic remains unchanged.
This allows follow-up patches to change how the renderer chooses the
primary GPU. It will be easier for the renderer to use private
information for choosing.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/271
This is a step towards moving the primary GPU logic into the native
renderer exclusively. In the future the renderer will have one more
criterion on choosing the primary GPU than MetaMonitorManagerKms should
know about: does a GPU offer hardware rendering.
The choosing of primary GPU is separated from the discovery of GPUs.
When GPUs are discovered and added to the list, the MetaGpuKmsFlag is
now populated correctly and used in choosing.
Choosing the primary GPU is done after all GPUs have been found and is
slightly different from before:
- Skipping devices that do not belong to our seat now works instead of
becoming the primary GPU.
- Fall back to any non-platform, non-boot_vga device if neither kind is
found.
The old preference of platform over boot_vga device is kept.
The hotplug path will continue creating a gpu_kms without flags, because
at that point the primary GPU has already been chosen and the flags are
irrelevant.

I saw Meson fade from the sky
On the wind I heard a sigh
As snowflakes cover fallen Makefiles
I will say this last goodbye
Meson is now coming
So ends Autotools days
Future is now coming
And we must away
Over Python and without Bashisms
Through lands where never Meson touched
By silver streams that run down to the Sea
Under parsers, beneath old legacy
Over snow one winter’s morn
I turned at last to paths that lead home
And though where the road then takes me
I cannot tell
We came all this way
But now comes the day
To bid you farewell
Many places I have been
Many sorrows I have seen
But I don’t regret
Nor will I forget
All Makefiles that took that road with me
I bid you all a very fond farewell.
If a library is provided in the positional arguments, then meson
defaults to installing the .pc file in a 'pkgconfig' subdirectory
in the library's install location. We want the files in the regular
$libdir/pkgconfig rather than $libdir/mutter-$api/pkgconfig, so
specify the location explicitly in the parameters.

This is a simple libcanberra abstraction object, so we are able

Dependencies are added automatically, and we no longer get warnings
like:
clutter/clutter/meson.build:628: DEPRECATION: Library mutter-clutter-4

mutter-clutter-4 to "Requires" field, but this is a deprecated behaviour
that will change in a future version of Meson. Please report the issue
if this warning cannot be avoided in your case.
The texture tower can return no texture e.g. if the calculated level is
negative. This was handled before, but regressed with

observed occasionally when starting Firefox nightly using the Wayland

If a KMS device has the DRM_CAP_DUMB_PREFER_SHADOW and a software based

in the llvmpipe OpenGL implementation, making blend operations faster.

Now that everything is settled, from the initialization
process to the subclasses to moving code to the compositor,
MetaWindowActor can be a proper abstract class that cannot
be instantiated.
Thus, make MetaWindowActor an abstract class.

This vfunc was added as a was to work around the convoluted
initialization process. Now that we figured it out and moved
the MetaWindowActor-specific initialization to constructed(),
we can override that.
Remove post_init() and use GObject.constructed() entirely.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/368
MetaWindowActor breaks layering isolation by accessing
and injecting itself into compositor->windows. This is
a bad practice, and effecticely makes returning the
new actor useless, since we doesn't even use the return
value.
Move window actor creation to under MetaCompositor and
stop violating (too badly) the resposabilities of each
component. This moves meta_window_actor_new() into
meta_compositor_add_window().
Also, move the remaining initialization code to the
GObject.constructed vfunc.

Document the roles of MetaSurfaceActor and MetaWindowActor,

MetaWindowActor handles sending _NET_WM_FRAME_* X atoms to
clients - even pure Wayland clients.
Now that we have Wayland- and X11-specific implementations of
MetaWindowActor, we can delegate this to MetaWindowActorX11,
and allow pure Wayland apps to not even connect to
MetaSurfaceActor:repaint-scheduled.
Do that by moving all the X11-specific code to the X11-specific
MetaWindowActorX11 class. Add vfuncs to MetaWindowActorClass
that are necessary for the move, namely:
* pre_paint() and post_paint()
* post_init()
* frame_complete()
* set_surface_actor()
* queue_frame_drawn()
https://gitlab.gnome.org/GNOME/mutter/merge_requests/368
Those are stub specialized classes for MetaWindowActor. This will
help ensuring that we do not execute X11-specific code paths on
pure Wayland clients.
The relationship between the window actor and the surface is the
following:
* Wayland: MetaWindowActorWayland + MetaSurfaceActorWayland
* X11: MetaWindowActorX11 + MetaSurfaceActorX11
* Xwayland: MetaWindowActorX11 + MetaSurfaceActorWayland
It is not possible to have MetaWindowActorWayland backed by a
MetaSurfaceActorX11 surface.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/368
We will introduce specialized MetaWindowActors for X11
and Wayland in the future, so it needs to be derivable.
Make it a derivable class, and introduce a private field.
The MetaWindowActorClass definition is in the private
header in order to prevent external consumers of Mutter
to create MetaWindowActor implementations of their own.
That is, MetaWindowActor is only internally derivable.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/368
EGLStream textures are imported as GL_TEXTURE_EXTERNAL_OES and reading
pixels directly from them is not supported. To make it possible to get
pixels, create an offscreen framebuffer and paint the actor to it, then
read pixels from the framebuffer instead of the texture directly.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/362
When a texture is transformed in any way (e.g. Wayland buffer
transforms), we cannot just fetch the pixels from the texture directly
and be done with it, as that will result in getting the untransformed
pixels.
To properly get the pixels in their right form, first draw to an
offscreen framebuffer, using the same method as when painting on the
stage, then read from the framebuffer into a cairo image surface.

Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/408
While for normal textures, GL_TEXTURE_2D should be used, when it's an external
texture, binding it using GL_TEXTURE_2D results in an error.
Reading the specification for GL_TEXTURE_EXTERNAL_OES it is unclear whether
getting pixel data from a texture is possible, and tests show it doesn't result
in any data, but in case it would eventually start working, at least bind the
correct target for now.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/362
Don't just set the internal format to the dummy format "any", as that causes
code intended to be unreachable code to be reached. It's not possible to
actually know the internal format of an external texture, however, so it might
not actually correspond to the real format.

DRM_EVENT_CONTEXT_VERSION is the latest context version supported by
whatever version of libdrm is present. Mutter was blindly asserting it
supported whatever version that may be, even if it actually didn't.
With libdrm 2.4.78, setting a higher context version than 2 will attempt
to call the page_flip_handler2 vfunc if it was non-NULL, which being a
random chunk of stack memory, it might well have been.
Set the version as 2, which should be bumped only with the appropriate
version checks.

This makes the build less verbose, as all .gir generation except for
clutters didn't pass --quiet to g-ir-scanner, making it output long
linking commands. Do this by adding a common introspection_args
variable.
While at it, put -U_GNU_SOURCE in there too, as it was always passed
everywhere as without it the scanner would log warnings.
This is the last remaining feature necessary to achieve
parity with the Autotools build.
A few changes were made to the install locations of the
tests, in order to better acomodate them in Meson:
* Tests are now installed under a versioned folder (e.g.
/usr/share/installed-tests/mutter-4)
* The mutter-cogl.test file is now generated from an .in
file, instead of a series of $(echo)s from within Makefile.
Notice that those tests need very controlled environments
to run correctly. Mutter installed tests, for example, will
failed when running under a regular session due to D-Bus
failing to acquire the ScreenCast and/or RemoteScreen names.
When running installed tests, the working directory for Cogl
tests is /usr/libexec/installed-tests/mutter-cogl-4/conform,
which isn't writable by normal users.
To avoid the adding stray hidden files to the current directory,
adapt the runner script to fallback to $(mktemp) - which is
available on all platform we care about - and avoid adding
hidden files everywhere.
Presumably glReadPixels itself can be more performant with pixel format
conversions than doing a fix-up conversion on the CPU afterwards. Hence,
pick required_format based on the destination rather than the source, so
that it has a better chance to avoid the fix-up conversion.
With CoglOnscreen objects, CoglFramebuffer::internal_format (the source
format) is also wrong. It is left to a default value and never set to
reflect the reality. In other words, read-pixels had an arbitrary
intermediate pixel format that was used in glReadPixels and then fix-up
conversion made it work for the destination.
The render buffers (GBM surface) are allocated as DRM_FORMAT_XRGB8888.
If the destination buffer is allocated as the same format, the Cogl
read-pixels first converts with glReadPixels XRGB -> ABGR because of the
above default format, and then the fix-up conversion does ABGR -> XRGB.
This case was observed with DisplayLink outputs, where the native
renderer must use the CPU copy path to fill the "secondary GPU"
framebuffers.
This patch stops using internal_format and uses the desired destination
format instead.
_cogl_framebuffer_gl_read_pixels_into_bitmap() will still use
internal_format to determine alpha premultiplication state and multiply
or un-multiply as needed. Luckily all the formats involved in the
DisplayLink use case are always _PRE and so is the default
internal_format too, so things work in practise.
Furthermore, the GL texture_swizzle extension can never apply to
glReadPixels. Not even with FBOs, as found in this discussion:
https://gitlab.gnome.org/GNOME/mutter/issues/72
Therefore the target_format argument is hardcoded to something that can
never match anything, which will prevent the swizzle from being assumed.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/313
This function gets hit even today on relatively modern Intel systems (I
have a Haswell Desktop with Mesa 18.2.4) if the pixel format is right.
Presumably it makes things slower for no longer a reason.
According to cb146dc515, this
functionality was refactored into a workaround path in 2012. The commit
message mentions the problem existing before Mesa 8.0.2. The number
refers to https://bugs.freedesktop.org/show_bug.cgi?id=46631 .
The use case where I hit this is when improving support for DisplayLink
video outputs. These are used through a "secondary GPU", and since
DisplayLink does not have a GPU, Mutter uses the CPU copy path with Cogl
read-pixels[1]. If the DisplayLink framebuffer was allocated as
DRM_FORMAT_XRGB8888 (the only format it currently handles correctly),
mesa_46631_slow_read_pixels_workaround would get hit. The render buffer is
the same format as the framebuffer, yet doing the copy XRGB -> XRGB ends
up being slower than XRGB -> XBGR which makes no sense.
This patch is not sufficient to fix the XRGB -> XRGB copy performance,
but it is required.
This patch reverts CoglGpuInfoDriverBug into what it was before
cb146dc515.

The actor-shader-effect test actors are 50px wide, but we check the 51st
pixel. This went along undetected until "clutter: Avoid rounding
compensation when invalidating 2D actors" because the paint volumes were
made slightly bigger and the shaders paint all over them (I guess nobody
noticed those actors being actually ~52px wide).
Update the test to check the middle of the opposite edge, so we keep neatly
rounded numbers.
The test does a clutter_actor_set_scale_full() call that only updates
the scale center (i.e. no changes to scale-x/y), but expects to receive
notifications of actor scale changes.
Since "Revert "Revert "ClutterActor: Optimize away idempotent
scale/position updates"" these are optimized away, so just drop the
assumption.
The depth buffer is marked as invalid when 1) the framebuffer is just created,
and 2) whenever GL_DEPTH_TEST is enabled on it. This will ensure the
framebuffers attached depth buffer (if any) is properly cleared before it's
actually used, while saving needless clears while depth testing is disabled
(the default).

`meta_window_actor_capture_into()` implementation is still pretty crude

Typically, to stream the content of a window, we need a way to copy the
content of its window-actor into a buffer, transform relative input
coordinates to relative position within the window-actor and a mean to
get the window bounds within the buffer.
For this purpose, add a new GType interface `MetaScreenCastWindow` with
the methods needed for screen-cast window mode:
* meta_screen_cast_window_get_buffer_bounds()
* meta_screen_cast_window_get_frame_bounds()
* meta_screen_cast_window_transform_relative_position()
* meta_screen_cast_window_capture_into()
This interface is meant to be implemented by `MetaWindowActor` which has

Switch-configs are only to be used in certain circumstances (see

The shader used for computing a vignette currently has two
problems:
* The math is wrong such that the vignette isn't stretched
across the whole actor and so ends abruptly
* There is noticeable banding in its gradient
This commit corrects both problems by fixing the computing
and introducing noise dithering.
If a display device (touchscreen, tablet with libwacom integration flags)
does not receive a monitor through settings. Delegate on the
MetaInputMapper so it receives a mapping through heuristics.
This object takes care of mapping absolute devices to monitors,
to do so it uses 3 heuristics, in this order of preference:
- If a device is known to be builtin, it's assigned to the
builtin monitor.
- If input device and monitor match sizes (with an error margin
of 5%)
- If input device name and monitor vendor/product in EDID match
somehow (from "full", through "partial", to just "vendor")
The most favorable outputs are then assigned to each device, making
sure not to assign two devices of the same kind to the same output.
This object replaces (and is mostly 1:1 with) GsdDeviceMapper in
g-s-d. That object would perform these same heuristics, and let
mutter indirectly know through settings changes. This object allows
doing the same in-process.
Since now we don't set the swap throttled value based
on sync-to-vblank, we can effectively remove it from
Cogl. Throttling swap buffers in Cogl is as much a
historical artifact as sync-to-vblank. Furthermore,
it doesn't make sense to disable it on a compositor,
which is the case with the embedded Cogl.
In addition to that, the winsys vfunc for updating
whenever swap throttling changes could also be removed,
since swap throttling is always enabled now.
Removing it means less code, less branches when running,
and one less config option to deal with.
This also removes the micro-perf test, since it doesn't
make sense for the case where Cogl is embedded into the
compositor.

Externally setting the sync-to-vblank setting was a feature
added as a workaround to old Intel and ATI graphic cards, and
is not needed anymore. Furthermore, it doesn't make sense to
change it on a compositor whatsoever.
This commit removes all the ways to externally change this
setting, as well as the now unused API.

The xf86-input-wacom driver exports a property with the tool type as known by
the driver. This is a more reliable choice than guessing based on the device
name.
In the touchscreen case, we simply use is_touch_device() to guess which one of
the two options it is. Note that this code should never be hit anyway as we
would've succeeded earlier with a previous is_touch_device() call.
If we are lucky enough and the parent actor has the CLUTTER_ACTOR_NO_LAYOUT
flag, we would skip the relayout, but still redraw the parent actor in its
entirety.
In these cases, we can at least just redraw the area affected by the actor
being shown/hidden.
These calls don't actually affect the layout, but the paint order.
It seems safe to skip the full relayout/repaint of the parent actor,
and redraw only the area occupied by the affected child.
The nested stage tries to emulate how CRTCs are drawn, but fails to do
this when a stage view is scaled as it didn't adapt the viewport size
according to the stage view scale.

Add MUTTER_DEBUG_DUMMY_MONITORS_SPECS env variable support so that you can define
a ':' separated list of monitor specs in the form of WWWxHHH@RR that will be
available for configuring the nested mutter.
cogl_(fromebuffer)_set_viewport will implicitly cast away the fraction
of a floating point number, meaning if a coordinate calculation
resulted in just below the integer (which for example ~1.75 scaling on
a 1920x1080 did), we'd set a one pixel too narrow viewport. Fix this by
always rounding the floating point to the closest int before passing,
avoiding the precision loss.

When calculating the logical monitor layout size given a scale, don't

Placing persistant Wayland popups (e.g. not menus etc) in the o-r layer
breaks stacking order with other window trees (e.g. other client
windows), as the menu would get stuck in the o-r layer, i.e. on top,
even if the parent of the popup got lowered.
Fix this by placing the popups in the normal layer, relying on
transient-ness to keep stacking correct.
When destructing a xdg_toplevel, we'll disassociate the actor from the
MetaWaylandSurface, to allow it to animate out. After having done this,
avoid trying to set it as unreactive when unsetting the window.
This fixes the runtime warning:
clutter_actor_set_reactive: assertion 'CLUTTER_IS_ACTOR (actor)' failed
Before processing the buffer damage region, intersect it with the buffer
rectangle to avoid trying to damage content outside the surface.

This is to ensure we're rendering a red damage area that actually
represents what is being damaged.
Fixes an always-fullscreen red damage on bare metal Wayland and
GNOME Shell.
This is useful to visualize which parts of the screen are being
damaged.
Add a new 'damage-region' value for CLUTTER_PAINT and paint the
damaged regions accordingly.
This adds the required bits to wayland surfaces and ties them up
to the compositor parts.
The central part here is to recalculate the surface size accordingly
and to translate surface damage into buffer damage.
The choosen approach additionally lays groundwork for wp_viewporter
support, which is closely related in its nature.
A further explanation of buffer transforms from the specification:
> The purpose of this request is to allow clients to render content
> according to the output transform, thus permitting the compositor
> to use certain optimizations even if the display is rotated.
> Using hardware overlays and scanning out a client buffer for
> fullscreen surfaces are examples of such optimizations.
This adds the necessary bits to support Wayland buffer transforms.
The main part here is to properly setup the Cogl pipeline
and to recalculate the size of the painted area accordingly,
so culling etc. still works.

wp_viewporter support.

This commit includes following fixes for a few shell scripts:
1. Follow the best practice of quoting variables everywhere unless they
are used in places where word-splitting and globbing can never happen.
2. Replace `command` with $(command) because the latter is easier to use
and read.
3. Don't use "$@" in places expecting a string because it is an array
of strings instead of a single string.
Bash is not always installed in /bin and we should not hardcode the path
of it in source code which is expected to be built on many operating
systems and distributions.
Since most scripts using #!/bin/bash here doesn't have any bashism,
they can be converted to #!/bin/sh instead of using /usr/bin/env trick.
Commit 70036429bd mixed drag_origin and drag_surface, leading to warnings
and invisible drag icon. Fix this up so we correctly set up the feedback
actor. This will correctly display the DnD icon alongside the pointer.
It is meant to hold surfaces that require a ClutterActor, just like wl/xdg
shell surfaces and subsurfaces. Make it inherit from MetaWaylandActorSurface
so it gets that for free.
The type declaration is also made completely private, in order to avoid
cyclic dependency between meta-wayland-surface.h and
meta-wayland-actor-surface.h. We just require the GType fro assign_role()
anyway.
Modal ungrabs may be followed by other clients trying to grab themselves,
flush the connection so we ensure the right order of events on the Xserver
side.
An example of this is js/ui/modalDialog.js in gnome-shell, as the alt-F2
dialog may launch X11 clients trying to grab themselves, commit a40daa3c22
in gnome-shell handled the case and added a gdk_display_sync() call to
ensure no grab existed at the time of executing.
This commit aims to achieve the same built in MetaBackend. A full sync
seems excessive though, as we just need to make sure the server got the
messages queued before the other side tries to grab, a XFlush seems
sufficient for this.
The nested backend used the value from udev, meaning that one couldn't
configure the fake monitor if the laptop panel of the host was closed.
Avoid this annoyance by always having the nested backend claiming the
lid is open.
If meson tries to get ahead and generate object files for tests
at the same time than building libmutter, those may randomly fail
if meson did not create the libmutter generated headers yet.
Add those to the declared dependency, so the files are ensured to
be created before anything gets to use it.

It wasn't implemented by any subclass, it's not provided by DRM either.
And even if a subclass were to have only a file available, it could read
it into a GBytes as well and just use `read_edid()`.
Found this while working on !269.
It's a UI pattern that has been superseded by client-side decorations,
apps that used to set the hint have generally moved on to headerbars.
Given that and the limitation to server-side decorated X11 windows,
GTK4 removed the client-side API for setting the hint, it's time to
follow suite and retire the feature.

Since this changes the ABI, we also need to bump the libmutter API

Add support for getting hardware presentation times from KMS (Wayland
sessions). Also implement cogl_get_clock_time which is required to compare
and judge the age of presentation timestamps.
For single monitor systems this is straightforward. For multi-monitor
systems though we have to choose a display to sync to. The compositor
already partially solves this for us in the case of only one display
updating because it will only use the subset of monitors that are
changing. In the case of multiple monitors consuming the same frame
concurrently however, we choose the fastest one (in use at the time).
Note however that we also need !73 to land in order to fully realize
multiple monitors running at full speed.
This macro was introduced so as to be able to be built without GLib.
However, this feature was long ago removed, and in Mutter we depend on
it anyway, so let's get rid of it in favor of more consistency.
This is based on `g_clear_object`, so it will be a bit more consistent
to write (and prevents the headaches from accidentally forgetting a NULL
check).
Use cogl_framebuffer_read_pixels_into_bitmap () instead of
glReadPixels () for the CPU copy path in multi-GPU support.
The cogl function employs several tricks to make the read-pixels as fast
as possible and does the y-flip as necessary. This should make the copy
more performant over all kinds of hardware.
This is expected to be used on virtual outputs (e.g. DisplayLink USB
docks and monitors) foremost, where the dumb buffer memory is just
regular system memory. If the dumb buffer memory is somehow slow, like
residing in discrete VRAM or having an unexpected caching mode, it may
be possible for the cogl function perform worse because it might do the
y-flip in-place in the dumb buffer. Hopefully that does not happen in
any practical scenario.
Calling meta_renderer_native_gles3_read_pixels () here was conceptually
wrong to begin with because it was done with the Cogl GL context of the
primary GPU, not on the GL ES 3 context of a secondary GPU. However,
due eglBindAPI being a no-op in Mesa and the glReadPixels () arguments
being compatible, it worked.
This patch adds a pixel format conversion table between DRM and Cogl
formats. It contains more formats than absolutely necessary and the
texture components field which is currently unused for completeness. See
Mutter issue #323. Making the table more complete documents better how
the pixel formats actually map so that posterity should be less likely
to be confused. This table could be shared with
shm_buffer_get_cogl_pixel_format () as well, but not with
meta_wayland_dma_buf_buffer_attach ().
On HP ProBook 4520s laptop (Mesa DRI Intel(R) Ironlake Mobile, Mesa
18.0.5), without this patch copy_shared_framebuffer_cpu () for a
DisplayLink output takes 5 seconds with a 1080p frame. Obviously that
makes Mutter and gnome-shell completely unusable. With this patch, that
function takes 13-18 ms which makes it usable if not fluent.
On Intel i7-4790 (Mesa DRI Intel(R) Haswell Desktop) machine, this patch
makes no significant difference (the copy takes 4-5 ms).
The format will be needed in a following commit in the CPU copy path
which stops hardcoding another format and starts using the format the
dumb FB was created with.
Change the callers of init_dumb_fb () to use DRM format codes. DRM and
GBM format codes are identical, but since this is about dumb buffers,
DRM formats fit better.
The header /usr/include/gbm.h installed by Mesa says:
* The FourCC format codes are taken from the drm_fourcc.h definition, and
* re-namespaced. New GBM formats must not be added, unless they are
* identical ports from drm_fourcc.
That refers to the GBM_FORMAT_* codes.
Virtual keyboard and pointer are freed on session close, but the
virtual touchscreen isn't.
Avoid a leak by freeing the virtual touchscreen along with the rest of
virtual devices.
If a device (virtual or real) is removed while there are remaining
events queued for that device, the event loop may try to access the
event freed memory.
To avoid the issue, add a reference to the device when the event is
created or copied, and remove the reference once the device is freed.

We were using the connector_id for the winsys_id, but different
devices could have connectors with the same id. Since we use
winsys_id to uniquely identify outputs, use both the connector
id and the device id to avoid having outputs with the same id.
Mostly as expected, this port is also trivial. A small cleanup
accompanies this patch, making gen_texcoords_and_draw_cogl_rectangle()
receive the framebuffer that it should draw into.
Because ClutterText has a somewhat convoluted drawing routine,
replacing cogl_rectangle() here isn't as straightfoward as the
effects were.
A new CoglPipeline is now part of the ClutterText struct, and
is used to set the color of the background or the selection.
Another change is paint_selection() now receives a framebuffer
to draw into. The check for NULL framebuffer does not make
sense here, since there is always a draw framebuffer set
when in the drawing function. Because of that, the check is
now gone.
All those effects have the same basic pattern of setting a
color of a pipeline, then drawing a rect with cogl_rectangle().
Thus, replacing those was as easy as retrieving the draw
framebuffer and calling cogl_framebuffer_draw_rectangle() on it.
The default implementation of ClutterActor.pick() uses
cogl_rectangle() to draw the rectangle with the color
for picking.
Replace that by cogl_framebuffer_draw_rectangle(). A
static color pipeline had to be created in order to
hold the pick color.
Instead of using cogl_read_pixels(), which is deprecated and
uses the implicit framebuffer, pass the current CoglFramebuffer
and use cogl_framebuffer_read_pixels().
Another case of a simple and direct API translation. Instead of
using the deprecated cogl_clear() function, replace it by the
non-deprecated cogl_framebuffer_clear().
Following up last commit, this commit adds a CoglFramebuffer
argument to meta_shadow_paint(), and stops using the draw
framebuffer internally.
The only consumer of this API, MetaWindowActor, still passes
the draw framebuffer though.
MetaShadow.paint() uses Cogl implicit APIs (cogl_rectangle* ones, in
this case) to paint shadows with the shadow pipeline.
Replace those calls by cogl_framebuffer_draw_textured_rectangle()
calls, that achieve the exact same result but with the non-deprecated
API.
Python is not guaranteed to be installed in /usr/bin. This is especially
true for *BSD systems which don't consider Python as an integral part of

We already ran a Wayland client to test various Wayland paths. What was

The test stage runs the whole meson test suite inside Xvfb inside a dbus
session. Running inside Xvfb is required as the cogl, clutter and mutter
tests require to run on top of X11; the dbus session is required to make
mutter succeed in owning names on the bus.
This also updates the Dockerfile to include packages needed for running
tests.

The events-touch test tested that clutter could properly process evdev
touch events. It used uinput to post evdev touch events, thus only ran
when runnig the test as root. Running as non-root it'd just silently
pass. As Clutter doesn't process evdev touch events anymore,
libinput does, so the test is fairly pointless, so remove it.
Pausing the master clock didn't actually pause it if there was already a
scheduled frame in progress. This is problematic if one actually expects
to see no new frame scheduling to happen after pausing, for example it
caused actor 'pre-paint' to be signalled on actors, but nothing was ever
painted.
Avoid this by destroying the master clock source when pausing, and then
recreating it when resuming.

For Wayland outputs, we do not expose the actual transformation because
mutter does not support wl_surface.set_buffer_transform yet, instead we
swap the logical width and height when the output is rotated.
However, a client wishing to use the physical size would get confused,
so if the output is rotated, rotate the physical dimensions as well for
consistency.

When profiling gnome-shell it was found that one of the main triggers
of `clutter_actor_queue_relayout` during animations was
`clutter_actor_set_margin_internal` continuously setting the same

incurs full stage relayouts and reallocation. So just avoid redundant

Commit 8d3e05305 ("window: Force update monitor on hot plugs") added the
flag `META_WINDOW_UPDATE_MONITOR_FLAGS_FORCE` passed to
`update_monitor()` from `update_for_monitors_changed()`.
However, `update_for_monitors_changed()` may choose to call another code
path to `move_between_rects()` and `meta_window_move_resize_internal()`
eventually.
As `meta_window_move_resize_internal()` does not use the "force" flag,
we may still end up in case where the window->monitor is left unchanged.
To avoid that problem, add a new `MetaMoveResizeFlags` that
`update_for_monitors_changed()` can use to force the monitor update from
`meta_window_move_resize_internal()`.

Almost a decade old, lets just assume it's there. This makes the button
on cally-atktext-example work again when building with meson, and
probably other things too.
Instead of using gtk_css_provider_get_default(), add a
static GtkCssProvider and fetch it instead. Creating
GtkCssProviders consume a bit more memory, so keeping
a single one alive is slightly more memory saving.
It relied on indices in arrays determining tile direction and
non-obvious bitmask logic to translate to _GTK_EDGE_CONSTRAINTS. Change
this to explicitly named edge constraints, and clear translation methods
that converts between mutters and GTK+s edge constraint formats.
An unnecessary memory optimization, storing the tile mode as a 2 bit
unsigned integer, was used. While saving a few bytes, it made debugging
harder. Remove the useless byte packing.
If texture allocation fails (e.g. on an old GPU with size limit 2048)
then `update_fbo` would return `FALSE` but leaves `priv->offscreen`
as non-NULL. So the next paint will try to use the offscreen with a
`NULL` texture and crashes. The solution is simply to ensure that
`priv->offscreen` is NULL if there is no `priv->texture`, so the default
(non-offscreen) paint path gets used instead.

This will allow CoglFramebuffer and its implementations to be exposed
to GJS and other language bindings. This is a necessary part of the
bigger work to make framebuffer management explicit.
CoglOffscreen is effectively a CoglFramebuffer, but it isn't being marked as
such by the GType machinery. This makes it impossible for introspection to
correctly set this class up.
Fix that by adding a COGL_GTYPE_IMPLEMENT_INTERFACE() code into the declaration
of CoglOffscreen. This does not have any functional changes though.

Meson uses the 'dependencies' field to determine and

gudev and libudev might have different versions, and
since 361bf847 we require gudev >= 232 to be able to
use g_autoptr with gudev types.
Since the previous commit, however, the meson build
was using the same version for libudev and gudev.
Fix that by requiring different versions for gudev
(>= 232) and libudev (>= 228).
Continuous' latest udev version is 228, and that is
not going to change too soon. Since we do not depend
on udev 232 specific features or bugfixes, just lower
the minimum version and make Continouos happy.
This commit adds meson build support to mutter. It takes a step away
from the three separate code bases with three different autotools setups
into a single meson build system. There are still places that can be
unified better, for example by removing various "config.h" style files
from cogl and clutter, centralizing debug C flags and other configurable
macros, and similar artifacts that are there only because they were once
separate code bases.
There are some differences between the autotools setup and the new
meson. Here are a few:
The meson setup doesn't generate wrapper scripts for various cogl and
clutter test cases. What these tests did was more or less generate a
tiny script that called an executable with a test name as the argument.
To run particular tests, just run the test executable with the name of
the test as the argument.
The meson setup doesn't install test files anymore. The autotools test
suite was designed towards working with installed tests, but it didn't
really still, and now with meson, it doesn't install anything at all,
but instead makes sure that everything runs with the uninstalled input
files, binaries and libraries when running the test suite. Installable
tests may come later.
Tests from cogl, clutter and mutter are run on 'meson test'. In
autotools, only cogl and clutter tests were run on 'make check'.
The touch handling code uses evdev API, thus will not work on other
backends. Thus, put touch handling code behind runtime backend checks
and only include the code when native backend support is enabled.
Install include files in
$prefix/include/mutter-$apiversion/[clutter,cogl,...,meta]/, and
datafiles in /usr/share/mutter-$apiversion/.... We still would conflict
e.g. given that our gettext name is "mutter", and how keybindings are
installed, but it's a step in the right direction.
This is the filename convention you get when you define a shared module
in meson, and since there is no particular reason to not include the
"lib" prefix, lets make it easier to port it over. While at it,
de-duplicate the retrieval of the plugin name.
It'll be installed in the meta/ directory, so put the template files in
the corresponding directory in the tarball. This will also simplify the
port to meson.
While leaving the runtime checks in place, requiring xrandr 1.5 at build
time allows us to remove some seemingly unnecessary conditional
inclusion of functionality.
The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
testboxes was a binary that did unit testing, but it wasn't integrated
to the test system, so in effect, it was never run. Instead integrate it
into the other mutter unit tests. This includes changing a few of
meta_warning()s into g_warning()s so that the GTest framework can handle
them.
There are different unit-tests file generated containing lists of tests
the test-runner.sh should run. Running run-tests.sh read the unit-tests
in the current directory, which is inconvenient to do when using meson.
Closing a GdkDisplay during an event handler is not currently supported by Gdk

drmModePageFlip() is guaranteed to fail for the invalid FB id 0.
Therefore it never makes sense to call this function with such argument.
Disabling a CRTC must be done with SetCrtc instead, for example.
Trying to flip to FB 0 not only fails, but it also causes Mutter to
never try page flip on this output again, using drmModeSetCrtc()
instead.
There was a race in setting next_fb_id when a secondary GPU was using
the CPU copy path. Losing this race caused the attempt to
drmModePageFlip () to FB ID 0 which is invalid and always fails. Failing
to flip causes Mutter to fall back to drmModeSetCrtc () permanently.

Fix this race by first waiting for pending flips and only then
proceeding with the swap operations. This should be safe, because the
pending flips could have completed already before entering
meta_onscreen_native_swap_buffers_with_damage ().
We might unset focus, or already be out of focus (e.g. an X11 client or
clutter text entry is focused) when a text-input state is committed by
the client. We handled this before, except when text input was
explicitly disabled by the client, the Wayland text-input was in focus
by the input method, and it focused itself out.
Simplify the logic a bit by just dropping the state on the floor in all
cases where after any potential focus changes were done, we are not
focused.

Commit 840378ae68 changed the code to use XmbTextPropertyToTextList()
instead of gdk_text_property_to_utf8_list_for_display(), but didn't
take into account that the replacement returns text in the current
locale's encoding, while any callers (rightfully) expect UTF8.
Fix this by converting the text if necessary.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/227
The WM_NAME property is of type TEXT_PROPERTY, which is supposed to be
returned as UTF-8. Commit 840378ae68 broke that assumption, resulting
in crashes with non-UTF8 locales; however the "fix" of converting from
LATIN1 to UTF8 is wrong as well, as the conversion will spit out garbage
when the input encoding isn't actually LATIN1.
Now that the original issue in text_property_to_utf8() has been fixed,
we can simply revert the relevant bits of commit d62491f46e.

This allows input methods to inject key events with specific keyval/keycode,

If the user maps eg. Alt+F2 to a pad button, the MetaInputSettings will
send the full Alt press, F2 press, F2 release, Alt release sequence.
However the keycode corresponding to Alt is found in level 1, so the
Shift modifier gets unintendedly latched in addition to the Alt key
press/release pair.
We could probably improve keycode lookup heuristics so level=0 (and
no modifier latching) is preferred, but we can do without it altogether
for modifier keys.
In order to allow a window with a custom rule placement to be moved
together with its parent, the final rule used derived from the
constraining were used for subsequent constraints. This was not enough
as some constraining cannot be translated into a rule, such as sliding
across some axis.
Instead, make it a bit simpler and just remember the position relative
to the parent window, and use that the next time.
This is a rework of 5376c31a33 which
caused the unwanted side effects.

When constructing MetaMonitorsConfig objects, store which type
of switch_config they are for (or UNKNOWN if it is not such
type of config).
Stop unconditionally setting current_switch_config to UNKNOWN when
handling monitors changed events. Instead, set it to the switch_config
type stored in the MonitorsConfig in the codepath that updates logical
state. In addition to being called in the hotplug case along the same
code flow that generates monitors changed events, this is also called
in the coldplug case where a secondary monitor was connected before
mutter was started.
When creating the default linear display config, create it as a
switch_config so that internal state gets updated to represent
linear mode when this config is used.
The previous behaviour of unconditionally resetting current_switch_config
to UNKNOWN was breaking the internal state machine for display config
switching, causing misbehaviour in gnome-shell's switchMonitor UI when
using display switch hotkeys. The lack of internal tracking when the
displays are already in the default "Join Displays" linear mode was
then causing the first display switch hotkey press to do nothing
(it would attempt to select "Join Displays" mode, but that was already
active).

With Wayland, a window is not showing until it's shown. Until this
patch, the initial state of MetaWindow, on the other hand, was that a
window is initialized as showing. This means that for a window to
actually be classified as shown (MetaWindow::hidden set to FALSE),
something would first have to hide it.
Normally, this wasn't an issue, as normally we'd first create a window,
determine it shouldn't be visible (due to missing buffer), hide it
before the next paint, then eventually show it. This doesn't work if
mutter isn't drawing any frames at the moment (e.g. the user switched
VT), as we'd miss the hiding before showing as e result of a buffer
being attached. The most visible side effect is that a window can't be
moved as the window actor remains frozen.
This commit fixes this issue by correctly classifying a newly created
Wayland window as "hidden".

The clip and opaque region are both in a translated stage coordinate
space, where the origin is in the top left corner of the painted
texture. The painting, however, is in the texture coordinate space,
so when the texture is scaled, the coordinate spaces differ.
Handle this by transforming the clip and opaque region to texture
coordinate space before computing the blend region and the opaque region
to paint.

meta_renderer_native_gles3_read_pixels() was assuming that the target
buffer stride == width * 4. This is not generally true. When a DRM
driver allocates a dumb buffer, it is free to choose a stride so that
the buffer can actually work on the hardware.
Record the driver chosen stride in MetaDumbBuffer, and use it in the CPU
copy path. This should fix any possible stride issues in
meta_renderer_native_gles3_read_pixels().
Track the allocated dumb buffer size in MetaDumbBuffer. Assert that the
size is as expected in copy_shared_framebuffer_cpu().
This is just to ensure that Cogl and the real size match. The size from
Cogl was used in the copy, so getting that wrong might have written
beyond the allocation.
This is a safety measure and has not been observed to happen yet.
If drmModeAddFB2() does not work, the fallback to drmModeAddFB() can

To avoid a known race condition in the wl_output protocol documented in
https://phabricator.freedesktop.org/T7722, mutter delays the `wl_output`
destruction but nullify the `logical_monitor` associated with the
`wl_output` and the binding routine `bind_output()` makes sure not to
send wl_output events if the `logical_monitor` is `NULL` (see commit
1923db97).
The binding routine for `xdg_output` however does not check for such a
condition, hence if the output configuration changes while a client is
binding to xdg-output (typically Xwayland at startup), mutter would
crash while trying to access the `logical_monitor` which was nullified
by the change in configuration.
Just like `bind_output()` does for wl_output, do not send xdg-output
events if there is no `logical_monitor` yet.

Changes in window decoration result in the window being reparented

The compositor will automatically unredirect the top most window which
is fully visible on screen. When unredirecting windows, it also shapes
the compositor overlay window (COW) so that other redirected windows
still shows correctly.
The function `get_top_visible_window_actor()` however will simply walks
down the window list, so if a window is placed on a layer above and
unredirected, then iconified by the client, it will still be picked up
by `get_top_visible_window_actor()` and he compositor will reckon it's
still unredirected while not in a visible state anymore, thus leaving a
black area on screen.
Make sure we skip the windows not known to the compositor while picking
the top visible window actor to avoid this issue.

Previously, trackballs were detected based on the presence of the
substring "trackball" in the device name. This had the downside of
missing devices, such as the Kensington Expert Mouse, which don't have
"trackball" in their names.
Rather than depending on the device name, use the ID_INPUT_TRACKBALL
property from udev to determine whether or not to treat a device as a
trackball.
This adds a new function, `is_trackball_device`, to MetaInputEvents, and
eliminates the `meta_input_device_is_trackball` function.

If an effect is active and it overrides the paint volume, we should
always recompute the paint volume when requested and not use the
cache, since the paint volume override can change from call to
call depending on what phase of painting we are in. For instance,
if we are part way through painting effects and request the
paint volume, the paint volume should only go up to the current
effect, but in a later call to compute repaint regions, the
paint volume needs to expand to accomadate the effect.
This still involves a lot of recomputation in the case of effects -
in a later clutter version it would be worth adding an API to
allow effects to explicitly recompute and return a new the paint
volume up to the current effect as opposed to recomputing
the cached one.
Previously we were checking l->data != NULL || (l->data != NULL &&
l->data != priv->current_effect). This would continue the loop even
if l->data == priv->current_effect, since l->data != NULL, which was
not the intention of that loop.
We also don't need to check that l->data != NULL before checking if
it does not match the current_effect, since we already checked
that current_effect was non-NULL before entering the loop.
On Wayland, xdg-foreign would leave a modal dialog managed even after

This is sub-optimal and this breaks the atomic relationship one would

Wayland native windows.

Some tablets have a noticable pointer jump on tip down/up, causing unintended
lines during drawing. Likewise, a button event may have an axis update that we

A window placed using a placement rule should keep that relative
position even if the parent window moves, as the position tied to the
parent window, not to the stage. Thus, if the parent window moves, the
child window should move with it.
In the implementation in this commit, the constraints engine is not
used when repositioning the children; the window is simply positioned
according to the effective placement rule that was derived from the
initial constraining, as the a xdg_popup at the moment cannot move
(relative its parent) after being mapped.

A popup can be reset, and when that happens, window and actor are
destroyed, and won't be created again unless it is reassigned the
popup role.
If a client queued frame callbacks when resetting a popup, the frame
callbacks would be left in the pending state, as they were not queued on
the actor, meaning we'd hit an assert about the frame callbacks not
being handled. Fix this by caching them on the MetaWaylandSurface, so
that they either are cleaned up on destruction, or queued on the actor
would the surface be re-assigned the popup role.

Sometimes it may be useful for roles to put callbacks in the generic

When a xdg-toplevel is reset, the window and actor are recreated, and

commit state, later hitting an assert as they were not handled.
Fix this by queuing the frame callbacks no the new actor, so that they
are emitted whenever the actor is eventually painted.

This was done for input regions in commit 718a89eb2f (Thanks Jonas
for the archaeology!) but opaque regions follow the same scaling.
This brings less evident issues as opaque regions are just used for
culling optimizations.
Commit 6a92c6f83 unintendedly broke input/opaque region calculations
on hidpi. Most visible side effect is that clicking is only allowed
in the upper-left quarter of windows.
The surface coordinates are returned in logical unscaled buffer
size. We're however interested in actor coordinates (thus real
pixels) here.
As it is a bit of a detour how the scale to be applied is calculated,
refactor a meta_wayland_actor_surface_get_geometry_scale() function
that we can use it here, and use it consistently for surface size and
the given regions.
Commit a3da4b8d5b changed updating of
window monitors to always use take affect when it was done from a
non-user operation. This could cause feed back loops when a non-user
driven operation would trigger the changing of a monitor, which itself
would trigger changing of the monitor again due to a window scale
change.
The reason for the change, was that when the window monitor changed due
to a hot plug, if it didn't actually change, eventually the window
monitor pointer would be pointing to freed memory.
Instead of force updating the monitor on all non-user operations, just
do it on hot plugs. This allows for the feedback loop preventing logic
to still do what its supposed to do, without risking dangling pointers
on hot plugs.

As per specification
> The compositor ignores the parts of the input region that
> fall outside of the surface.
> The compositor ignores the parts of the opaque region that
> fall outside of the surface
This fixes culling problems under certain conditions.
`ClutterText` painting for editable single_line_mode actors like `StEntry`
is always clipped by:
`cogl_framebuffer_push_rectangle_clip (fb, 0, 0, alloc_width, alloc_height)`
So it's difficult to get the rectangle wrong. However in cases where the
target framebuffer has changed (`cogl_push_framebuffer`) such as when
updating `ClutterOffscreenEffect` we had the wrong old value of `fb`. And
so would be clipping the wrong framebuffer, effectively not clipping at all.
Currently xdg-shell applies a geometry set with set_window_geometry
unconditionally. But the specification requires:
> When applied, the effective window geometry will be
> the set window geometry clamped to the bounding rectangle of the
> combined geometry of the surface of the xdg_surface and the
> associated subsurfaces.
This is especially important to implement viewporter and
transformation.
By using the shm file when sending the keymap to all clients, we
effectively allows any client to change the keymap, as any client has
the ability to change the content of the file. Sending a read-only file
descriptor, or making the file itself read-only before unlinking, can
be worked around by the client by using chmod(2) and open(2) on
/proc/<pid>/<fd>.
Using memfd could potentially solve this issue, but as the usage of
mmap with MAP_SHARED is wide spread among clients, such a change can
not be introduced without causing wide spread compatibility issues.
So, to avoid allowing clients to interfere with each other, create a
separate shm file for each wl_keyboard resource when sending the
keymap. We could eventually do this per client, but in most cases,
there will only be one wl_keyboard resource per client anyway.

If a client maps a popup in response to a key-down event, but the
mapping doesn't occur until after the user has already released the same

often presses and releases a key quite quickly, meaning any popup mapped
on key-down are likely to be dismissed.
Avoid this race condition by accepting serials for key down events, if
the most recent key-up event had the same keycode.

For historical reasons meta_monitor_is_active() checked whether it is
active by checking whether the main output have a CRTC assigned and
whether that CRTC has a current mode. At a later point, the MetaMonitor
got its own mode abstraction (MetaMonitorMode), but
meta_monitor_is_active() was never updated to use this.
An issue with checking the main output's CRTC state is that, if there is
some CRTC mode combination that for some reason isn't properly detected
by the MetaMonitorMode abstraction (e.g. some tiling configuration not
yet handled), meta_monitor_is_active() would return TRUE, even though no
(abstracted) mode was set. This would cause confusion here and there,
leading to NULL pointer dereferences due to the assumption that if a
monitor is active, it has an active mode.
Instead, change meta_monitor_is_active() to directly check the current
monitor mode, and log a warning if the main output still happen to have
a CRTC with a mode assigned to it. This way, when an not undrestood CRTC
mode combination is encountered, instead of dereferencing NULL pointers,
simply assume the monitor is not active, which means that it will not be
managed or rendered by mutter at all.

We refuse to move focus while a grab operation is in place. While this
generally makes sense, there's no reason why the window that owns the
grab shouldn't be given the regular input focus as well - we pretty
much assume that the grab window is also the focus window anyway.
In fact there's a strong reason for allowing the focus change here:
If the grab window isn't the focus window, it probably has a modal
transient that is focused instead, and a likely reason for the focus
request is that the transient is being unmanaged and we must move
the focus elsewhere.

Add API to let GNOME Shell have the ability to get notified about remote

This is done by adding an abstraction above the remote desktop and

cogl source code shows that it does and must use the same clock as
`cogl_get_clock_time`.

This test aims at checking that the transient relationship set using the
xdg-foreign API is respected by mutter and that no crash occurs, such as
the one in issue !174.
Note: the crash from issue !174 occurs only if "attach_modal_dialogs" is
set, so one has to change that default value to "true" to be able to
trigger the crash:
gsettings set org.gnome.mutter attach-modal-dialogs true

Add a "set_parent_exported" command to test the xdg-foreign support, so
that we can add a test which uses the GDK API for exported window:
`gdk_wayland_window_set_transient_for_exported()`
That will allow to detect if transient is applied correctly between
foreign windows and detect possible crashes such as issue !174.

Monitor whether UPower is running ourselves. That allows us to keep the
same value for "lid-is-closed" throughout the process of UPower
restarting, preventing unwanted monitor re-configuration through the process.
Fixes another screen black out when UPower restarts and the laptop lid
is closed.
Rather than handle UpClient in both MetaBackend (to reset the idletime
when the lid is opened), and in MetaMonitorManager and
MetaMonitorConfigManager (to turn the screen under the lid on/off
depending on its status), move the ability to get the lid status from
UPower or mock it in one place, in MetaBackend.
Restarting UPower will make every property of UpClient emit a "notify"
signal (as a GDBusProxy would). Avoid mutter reconfiguring the displays
when upower restarts by caching the last known value of "lid-is-closed"
and only reconfiguring the displays if it actually changed.
This fixes a black out of the screen when UPower restarts.
Previously we relied on the test-client to make sure that a window was
shown. For X11, we did not need to do anything, but for Wayland we had
to make sure we had drawn the first frame, otherwise mutter wouldn't
have a buffer making the window not showable.
Doing it this way doesn't work anymore however, since the 'after-paint'
event will be emitted even if we didn't actually paint anything. This is
the case with current Gtk under Wayland, where we won't draw until the
compositor has configured the surface. In effect, this mean we'll get a
dummy after-paint emission before the first frame is actually painted.
Instead, move the verification that a "show" command has completed by
having the test-runner wait for a "shown" signal on the window, which is
emitted in the end of meta_window_show(). This requires an additional
call to gdk_display_sync() in the test-client after creating the window,
to make sure that the window creation vents has been received in the
compositor.
As of "stack-tracker: Keep override redirect windows on top"
(e3d5bc077d), we always sorted all
override redirect on top of regular windows, as so is expected by
regular override redirect windows. This had an unwanted consequence,
however, which is that we should still not sort such override redirect
windows on top if they are behind the guard window, as that'd result in
windows hidden behind it now getting restacked anyway.
Fix this by only sorting the override redirect windows that are found
above the guard window on top. This fixes the override-redirect stacking
test.
The special ::pick implementation there makes clutter fall into paths
that do require a get_paint_volume() implementation, or an infinite
area will be used.
Providing a paint volume here is easier on the invalidation mechanism.
This optimization was presumably added before Clutter was able to
invalidate selected regions of an actor. Paint volumes are supposed
to be invariable as long as the actor conditions don't change.
Stacking of other actors shouldn't affect the paint volume, so it's
actually wrong to optimize those areas away here.
The framerate for screen cast sources was set to variable within 1 FPS
and the framerate of the monitor being screen casted. This meant that if
the sink didn't match the framerate (e.g. had a lower max framerate),
the formats would not match and a stream would not be established.
Allow letting the sink clamp the framerate range by setting it as
'unset', allowing it to be negotiated.
The PipeWire master branch saw some backports from the work branch,
including API changes making the 0.1 series more aligned with future
plans. Make mutter use the new API. This is needed to avoid dead locks
that existed in the older version.
xdg-foreign clears the `transient_for` of a modal dialog when its
imported parent is destroyed, which would later cause a crash in
`constrain_modal_dialog()` because the transient `NULL`.
So in case a modal dialog has no parent, do not try to constrain it
against its parent.

The test fix in commit 859bea629b broke distcheck, probably because
abs_srcdir is prefixed with a relative $BUILDROOT. Hopefully this is
the last autotools breakage before switching to meson, so don't
bother investigating too much ...
Force update the cursor renderer after theme or size changes; otherwise
we'll be stuck with the old theme and/or size until something else
triggers resetting of the cursor.
MetaDisplay still had workspace signals, but nothing emitted them,
meaning we wouldn't get warnings if handlers were added there instead
of to MetaWorkspaceManager.

If we wait with opening the X11 window decoration GDK connection, we
might end up with a terminated X11 server before we finish
initializing, depending on the things happening after spawning Xwayland
and before opening the MetaX11Dispaly. In gnome-shell, this involves
e.g. creating a couple of temporary X11 connections, and on disconnect,
if they happen to be the last client, the X server will terminate
itself.
https://bugzilla.gnome.org/show_bug.cgi?id=759538
Under Xorg the cursor size preference was pre-scaled originating from
gtk, while with Wayland it came directly from GSettings remaining
unscaled. Under Xwayland this caused the X11 display code to set the
wrong size with HiDPI configurations, which was often later overridden
by the equivalent code in gtk, but not always.
Fix this by always having the cursor size preference unscaled, scaling
the size correctly where it's used, depending on how it's used.

Split X11 specific parts into MetaX11Display. This also required
changing MetaScreen to stop listening to any signals by itself, but
instead relying on MetaDisplay forwarding them. This was to ensure the
ordering. MetaDisplay listens to both the internal and external
monitors-changed signal so that it can pass the external one via the
redundant MetaDisplay(prev MetaScreen)::monitors-changed.

For some reason "backends: Remove X11 idle-monitor backend" removed
unrelated warning messages for when generated monitor configurations
that should work didn't, which also made the unit tests fail.
This commit adds them back, which also makes the tests pass again.
Commit 22723ca37 moved buffer realization to
meta_wayland_surface_commit() so that it wouldn't be part of
meta_wayland_buffer_attach().
However, creation of dmabuf buffers would call into
meta_wayland_buffer_attach() directly without realizing the buffer
first. attach() would then fail and mutter would effectively shut down
any clients using the zwp_linux_dmabuf protocol (note that if such
client was Xwayland, mutter itself would shut down as well).
Add the missing bit in order to make zwp_linux_dmabuf protocol work
again.
One of the current limitations of EGLStreams is that there's no way to
resize a surface consumer without re-creating the entire stream.
Therefore, while resizing, clients will send wl_surface::attach requests
so the compositor can re-create its endpoint of the stream, but no
buffer will be available actually. If we proceed with the rest of the
attach operation we'll be presenting an empty buffer.
In order to fix this, a separate wl_eglstream_controller protocol has
been introduced that clients can use to request a stream re-creation
without overloading wl_surface::attach for that purpose.
This change adds the required logic to create the corresponding
wl_eglstream_controller global interface that clients can bind to.
Whenever a client requests a stream to be created, we just need to
create and realize the new EGLStream buffer. The same buffer resource
will be given at a later time to wl_surface::attach, whenever new
content is made available by the application, so we can proceed to
acquire the stream buffer and update the surface state.
https://bugzilla.gnome.org/show_bug.cgi?id=782575
Clients using EGLStream-backed buffers will expect the stream to be
functional after wl_surface::attach(). That means the compositor-side
stream must be created and a consumer attached to it.
To resolve the above, this change realizes buffers even when the attach
operation is deferred (e.g. synchronized subsurfaces).
https://bugzilla.gnome.org/show_bug.cgi?id=782575
When dealing with synchronized subsurfaces, we defer buffer attachments
until the parent surface state is applied.
That causes interaction issues with EGLStream backed buffers, as the
client expects the compositor-side stream to be functional after it
requests a wl_surface::attach.
By allowing the compositor to realize buffers without attaching them, we
could resolve the issue above if we define a realized EGLStream buffer
as a functional EGLStream (EGLStream + attached consumer).
This change moves the texture consumer creation part from the attach
function to the realize one.

Commit 712ec30cd9 added the logic to only
choose EGL configs that match the GBM_FORMAT_XRGB8888 pixel format.
However, there won't be any EGL config satisfying such criteria for
non-GBM backends, such as EGLDevice.
This change will let us choose the first EGL config for the EGLDevice
backend, while still forcing GBM_FORMAT_XRGB8888 configs for the GBM
one.

Where to realize a hardware cursor depends on where on the screen it
will be displayed. For example it only needs buffers for the cursor
plane on a certain GPU if it overlaps with a monitor that is connected
said GPU.
Previously, we were too eager with uploading the cursor plane buffers,
which in effect resulted in the secondary GPU always being woken up
when changing the cursor, even though the cursor plane would actually
never be set unless the pointer cursor was moved to a monitor connected
to the secondary GPU. These wake-ups caused noticable stuttering; thus
by uploading the buffers more lazilly, the stuttering is avoided.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/77
When a cursor is hidden, the native backend will properly hide the HW
cursor sprite as well, but it would communicate this as if the cursor
was not handled by the backend, while in fact it still was. This caused
the generic cursor rendering layer to queue a redraw.
https://gitlab.gnome.org/GNOME/mutter/issues/77
When force-updating the HW state we might end up with a situation where
the HW cursor is no longer usable. If this would happen, we'd before
this commit not trigger the fallback paths using a GL texture.

Introduce a new type MetaCursorSpriteXcursor that is a MetaCursorSprite
implementation backed by Xcursor images. A plain MetaCursorSprite can

type.

It was prefixed with meta_cursor_, but it took a X11 Display, so update
the naming. Eventually it should be duplicated depending if it's a

now.

drmModeAddFB2 allows userspace to specify a real format enum on
non-ancient kernels, as an improvement over the legacy drmModeAddFB
which derives format from a fixed depth/bpp mapping.
As an optimisation, Weston used to decide at the first failure of
drmModeAddFB2 that the ioctl was unavailable: as non-existent DRM
ioctls return -EINVAL rather than -ENOSYS or similar, bad parameters are
not distinguishable from the ioctl not being present.
Mutter has also implemented the same optimisation for dumb framebuffers,
which potentially papers over errors for the gain of avoiding one ioctl
which will rapidly fail on ancient kernels. Remove the optimisation and
always use AddFB2 where possible.
