This commit completes the implementation of `xdg_wm_base` version 3,
which introduces support for synchronized implicit and explicit popup
repositioning.
Explicit repositioning works by the client providing a new
`xdg_positioner` object via a new request `xdg_popup.reposition`. If the
repositioning is done in combination with the parent itself being
reconfigured, the to be committed state of the parent is provided by the
client via the `xdg_positioner` object, using
`xdg_positioner.set__parent_configure`.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/705
This sets the `is_reactive` flag on the window placement rules, causing
the popups to be reconfigured as they are affected by environmental
changes, such as the parent moving in a way making the popup partially
offscreen.
As with synchronization, the implementation is dormant, as the
version of the advertised global isn't bumped yet, as the new protocol
version is not yet fully implemented.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/705
This commits adds support on the MetaWindow and constraints engine side
for asynchronously repositioning a window with a placement rule, either
due to environmental changes (e.g. parent moved) or explicitly done so
via `meta_window_update_placement_rule()`.
This is so far unused, as placement rules where this functionality is
triggered are not yet constructed by the xdg-shell implementation, and
no users of `meta_window_update_placement_rule()` exists yet.
To summarize, it works by making it possible to produce placement rules
with the parent rectangle a window should be placed against, while
creating a pending configuration that is not applied until acknowledged
by the client using the xdg-shell configure/ack_configure mechanisms.
An "temporary" constrain result is added to deal with situations
where the client window *must* move immediately even though it has not yet
acknowledged a new configuration that was sent. This happens for example
when the parent window is moved, causing the popup window to change its
relative position e.g. because it ended up partially off-screen. In this
situation, the temporary position corresponds to the result of the
movement of the parent, while the pending (asynchronously configured)
position is the relative one given the new constraining result.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/705
MetaGravity is an enum, where the values match the X11 macros used for
gravity, with the exception that `ForgetGravity` was renamed
`META_GRAVITY_NONE` to have less of a obscure name.
The motivation for this is to rely less on libX11 data types and macros
in generic code.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/705
A placement rule placed window positions itself relative to its parent,
thus converting between relative coordinates to absolute coordinates,
then back to relative coordinates implies unwanted restrictions for
example when the absolute coordinate should not be calculated againts
the current parent window position.
Deal with this by keeping track of the relative position all the way
from the constraining engine to the move-resize window implementation.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/705
To organize things a bit better, put the fields related to the placement
rule state in its own anonymous struct inside MetaWindow. While at it,
rename the somewhat oddly named variable that in practice means the
current relative window position.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/705
After popup placement rules have gone through the constraints engine has
ended up resulting in an actual move, pass the window configuration down
the path using relative coordinates, as that is what the next layer
(xdg-shell implementation) actually cares about.
In the future, this will also be helpful when the configured position is
not against the current state of the parent.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/705
A placement rule is always about placing a window relative to its
parent. In order to eventually place it against predicted future parent
positions, make the placement rule processing output relative
coordinates, having the caller deal with turning them into absolute.

meta_window_wayland_finish_move_resize() inhibited window moves to be
finished if there was a resize grab active at the time, in order to
handle window resizing. Change this to only affect the grabbed window
itself, so that e.g. a popup can be positioned according to a pending
configuration while there is an active resize grab.

This is made a signal, so the upper layers (read: gnome-shell) may
decide what services to spawn. The signal argument contains a task

This is used by GDK and the X11 bits, but may also be used for
other initialization services we might need to run along with
Xwayland initialization.
However, as the -initfd argument in Xwayland is a fairly new
feature, add some meson build-time checks so that the feature
is handled transparently while allowing to explicitly set/unset
it.

This shape region culling was wrongly implemented in f5a28aa9, as it
does not take frame offsets into account, and is also redundant, as
we already set the opaque region of the underlying surface accordingly.
The other parts were implemented in ac7aa114, the reason given in
the commit message:
```
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.
```
is wrong though - culling on X11 actors works just fine and did only
not work in Wayland sessions because of a bug that got fixed in
19814497.
In conclusion the whole part appears to be redundand and some testing
done suggests the same. Drop it.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1082
If a opaque region is explicitly set we should not consider the surface
opaque, as that implies e.g. a shape region is set.
If no opque region is set but the texture does not have an alpha channel,
we can savely cull it out.

We want sysprof's exact datadir for compatability with
platforms where software is installed into their own
individual immutable prefix's. Such that, mutter's prefix will
never equate to sysprof's. This depends on a MR in sysprof [0]
which adds datadir to its pkgconfig files, as these files will always
have the proper path we want.
This adds version a constraint on sysprof_dep, as datadir was added to
the .pc in this version.

Given that on Wayland we are pretty much guaranteed to finish MetaX11Display
setup after the MetaCompositor is enabled, we may drop the
meta_compositor_manage() x11 initialization bits, and move them into the
MetaX11Compositor subclass where it's actually needed.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/944
We artificially made Xwayland initialization synchronous, as we used
to rely on MetaX11Display and other bits during meta_display_open().
With support for Xwayland on demand and --no-x11, this is certainly
not the case.
So drop the main loop surrounding Xwayland initialization, and turn
it into an async operation called from meta_display_init_x11(). This
function is turned then into the high-level entry point that will
get you from no X server to having a MetaX11Display.
The role of meta_init() in Xwayland initialization is thus reduced
to setting up the sockets. Notably no processes are spawned from here,
deferring that till there is a MetaDisplay to poke.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/944
This ATM completes the task right away, but we will want to do
further things here that are asynchronous in nature, so prepare
for this operation being async.
Since the X11 backend doesn't really need this, make it go on
the fast lane and open the MetaX11Display right away, the case
of mandatory Xwayland on a wayland session is now handled
separately.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/944
With Xwayland initialization going async, these errors will seep
into the parts controlled by g_test*(), resulting in the harmless
errors about DBus names not acquired turned fatal.
Set an error log handler, and specifically ignore those.

It might not be available right on initialization time if X11 is started
asynchronously. As this is a requirement for our tests, ensure it is there

This used to be set on meta_compositor_manage(), but only if there is a
MetaX11Display. Given meta_display_init_x11() is Wayland only, and we can
always assume compositing to be enabled, just have it invariably set after
the X server is up.

Even though cogl_framebuffer_flush() was supposed to be enough,
it ends up creating streams with odd visual glitches that look
very much like unfinished frames.
Switch back to cogl_framebuffer_finish(), which is admittedly
an overkill, but it's what works for now. There is anedoctal
evidence showing it doesn't incur in worse performance.

Much like monitor streaming, implement window streaming by
making the window actor draw itself with a paint context

Unfortunately, PipeWire doesn't support modifiers properly, so use the
linear format for now. For now, a hardcoded format of DRM_FORMAT_XRGB8888
is set, so we don't need to negotiate the format with PipeWire early.

If the cursor sprite does not match the scale factor or transformation
of the monintor, we currently fall back to a software cursor, causing
redraws of the shell. This commit implements scaling and transforming
of the cursor sprite, so we can use it with hardware planes, too.
This commit does the following steps:
1. Make sure we reupload the cursor image if the cursor is over
a logical monitor not matching the scale or transform from the previous
update.
2. Before upload to the hardware plane, scale and transform the cursor
image if possible and necessary.
3. Make sure we always use the hardware cursor if possible (only fall
back to software/OGL cursor if it is visible on multiple logical monitors
with differet scales/transforms).
4. Transform or scale the cursor coordinates if necessary.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/526
In Wayland clients can commit transformed surfaces, so the compositor
can directly use them on hardware planes. We already support that
for other surfaces, this is the first step to also support it on
cursor sprites.

This may be used indirectly before creation as we dispatch libinput events

When applying a configuration to XRANDR, we first disable CRTCs that
happen to extend outside of the to-be X11 screen size. While doing so,
we fail to actually check whether the CRTC is active or not, meaning
we'll try to query the content of the CRTC configuration even though it
has none, leading to a NULL pointer dereference.
Fix this by simply ignoring non-configured CRTCs.

Instead of users fetching it via `clutter_stage_get_redraw_clip()`, pass
it via the paint context. This is helpful as it is only valid during a
paint, making it more obvious that it needs to be handled differently
when there is no redraw clip (i.e. we're painting off-screen).
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1042
Prior to this commit the stage was drawn separately for each logical
monitor. This allowed to draw different parts of the stage with
different transformations, e.g. with a different viewport to implement
HiDPI support.
Go even further and have one view per CRTC. This causes the stage to
e.g. draw two mirrored monitors twice, instead of using the same
framebuffer on both. This enables us to do two things: one is to support
tiled monitors and monitor mirroring using the EGLStreams backend; the
other is that it'll enable us to tie rendering directly to the CRTC it
will render for. It is also a requirement for rendering being affected
by CRTC state, such as gamma.
It'll be possible to still inhibit re-drawing of the same content
twice, but it should be implemented differently, so that it will still
be possible to implement features requiring the CRTC split.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1042
To make it more reliable to distinguish between values that are read
from the backend implementation (which is likely to be irrelevant for
anything but the backend implementation), split out those values (e.g.
layout).
This changes the meaning of what was MetaCrtc::rect, to a
MetaCrtcConfig::layout which is the layout the CRTC has in the global
coordinate space.

On x11 we emulate pointer events from touch events as long as there's
only one touchpoint on screen, this obviously leads to x11 sending us
crossing events triggered by the emulated pointer. Now if we get a leave
event and set the stage of the ClutterInputDevice to NULL, new touch
events will be discarded by clutters backend because the core pointer
doesn't have a stage associated. This means Mutter completely loses
state of a touchpoint as soon as it crosses a shell actor.
An easy reproducer for this issue is to start the four-finger-workspace
gesture above a window and to move the pointer emulating touch outside
of the window, this will freeze the gesture as the gesture no longer
receives touch events.
To fix this, stop tracking stage changes on crossing events and simply
leave the ClutterInputDevice stage as-is. In our case there is only one
stage anyway and that won't change in the future.

The check-alive feature is there for the user to be able to terminate
frozen applications more easily. However, sometimes applications are
implemented in a way where they fail to be reply to ping requests in a
timely manner, resulting in that, to the compositor, they are
indistinguishable from clients that have frozen indefinitely.
When using an application that has these issues, the GUI showed in
response to the failure to respond to ping requests can become annoying,
as it disrupts the visual presentation of the application.
To allow users to work-around these issues, add a setting allowing them
to configure the timeout waited until an application is considered
frozen, or disabling the check completely.

It is only useful for clients that do not set an opaque region but
still can be detected as being opaque. This is helpful for X11 clients
as opaque regions only got introduced around 2012 and only as part of EWMH
and are thus not used in many cases.
On Wayland however opaque regions have been part of the core protocol from the
beginnig and we can assume they are used more commonly.
As the current implementation in `MetaWindowActor` does not handle Wayland
subsurfaces well, instead of adding more complexity just move it to
`MetaWindowActorX11`.
While on it, take the shape region into account that is set when clients
use the X Nonrectangular Window Shape Extension Protocol, so we have exact
culling with those clients.

There are two surface roles owning a MetaWindow: MetaWaylandShellSurface
(basis of MetaWaylandXdgToplevel, MetaWaylandXdgPopup,
MetaWaylandWlShellSurface, etc), and MetaXwaylandSurface.
With these two role types, the MetaWindow has two different types of
life times. With MetaWaylandShellSurface, the window is owned and
managed by the role itself, while with MetaXwaylandSurface, the
MetaWindow is tied to the X11 window, while the Wayland surface and its
role plays more the role of the backing rendering surface.
Before, for historical reasons, MetaWindow was part of
MetaWaylandSurface, even though just some roles used it, and before
'wayland: Untie MetaWindowXwayland lifetime from the wl_surface' had
equivalent life times as well. But since that commit, the management
changed. To not have the same fied in MetaWaylandSurface being managed
in such drastically different ways, rearrange it so that the roles that
has a MetaWindow themself manages it in the way it is meant to; meaning
MetaWaylandShellSurface practically owns it, while with Xwayland, the
existance of a MetaWindow is tracked via X11.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/835
The role determines how a relative coordinate is calculated. More
specifically, using clutters API to transform coordinates is only
accurate right after a clutter layout pass but this function is used
e.g. to deliver pointer motion events which can happen at any time. This
isn't a problem for Wayland clients since they don't control their
position, but X clients do and we'd be sending outdated coordinates if a
client is moving a window in response to motion events.
This was already done already, but now move the Xwayland specific logic
to the Xwayland surface role, keeping the generic transformation logic
in the generic actor surface role.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/835
The shell surface role is the one where subsurfaces may exist, and it
has direct relation to the MetaWindowActorWayland which currently has
the subsurface stacking logic.
Instead of directly finding the window actor when dealing with
subsurfaces, notify the parent surface that the subsurface state
changed, so that it can outsource the application of this information to
the role. For subsurface roles, this simply means forward upward to the
parent; for shell surface roles, this means regenerate the surface actor
layering.
This allows us to move away from accessing the window directly from the
surface, which in turn allows us to change the ownership structure of
windows.

If a window already is being pinged, it doesn't make sense to send more

Using a timestamp twice in a row (e.g. when activating two windows in
response to the same event or due to other bugs) will break the window
detection and show a close dialog on the wrong window. This is a grave

the ping for uniqueness and if the timestamp was already used and its
ping is still pending, log a warning message and don't send the ping.

Increase the number of checks whether a window is still responsive and
ping windows on every call to `meta_window_focus()` instead of

dialog will eventually get shown.

Currently when a window is requested to be unredirected, the
corresponding pixmap and texture can get cleared before the window has
been unredirected by the X server. This can result in the windows behind
showing through which causes a short flicker after showing an OSD or
notification when a fullscreen application is running.
Fix this by ensuring the texture is only cleared after the window has
been unredirected by the server.
Similarly when the window is being redirected again, the pixmap of the
window can only be requested after the redirection has been completed by
the server. This currently can happen in a different frame than the next
redraw of the actor resulting in an empty texture until the next redraw.
Fix this by queuing a redraw immediately after redirecting.

By default clutter will show an actor as it is added to a parent. This
means that after we create the window actor, when it's added to the
window group, we implicitly show it. What we really want is to not show
it until the window is supposed to be shown, which happens when
meta_window_actor_show() is called, as showing prior to that, could
cause issues.
Avoid the implicit show by setting the "show-on-set-parent" property on
the window actor to `FALSE` on window actor construction.

The clip bounds passed in `meta_window_actor_capture_into()` represent

As such, it is completely agnostic to the scaling factors that might

The actors of Wayland subsurfaces are set to be reactive on creation,
when receiving the `wl_subcompositor.get_subsurface` request.
However, if a client creates several subsurfaces and then creates the
xdg_toplevel object after, the previous subsurface actors are reset.
As a result, Clutter picking will skip and ignore those actors in
`clutter_actor_should_pick_paint()` because they aren't marked as
reactive anymore.
An example of such a client being affected by this issue is SCTK, the
Rust library implementing client side decorations for Wayland used
internally by winit and alacritty.
Move the `set_reactive()` call from `get_subsurface()` to the subsurface
`sync_actor_subsurface_state()` vfunc to make sure those remain reactive

create_for_builtin_display_rotation this means that we will now also honor
"rotate-monitor" hotkey keypresses when there is more than 1 monitor and
update the builtin display rotation instead of ignoring "rotate-monitor"
hotkey keypresses when there is more than 1 monitor. If this is deemed
undesirable this is easy to fix, but I believe that doing things this way
is more consistent.

Add a clone_logical_monitor_config_list helper function for making a deep
copy of MetaLogicalMonitorConfig lists.
This is a preparation patch for honoring accelerometer value changes when
there is more than 1 monitor.

When creating a new config because of a monitor being (un)plugged or
because of super+p being pressed, honor the orientation reported by
the accelerometer for the internal panel.
Before this commit we would always configure the internal panel with
a normal / upright transform when e.g. an external monitor gets plugged
in even if another transform was in use before plugging in the external
monitor. This is inconsistent and causes problems for several use-cases.
This commit fixes this by querying the accelerometer when creating a new
config for an internal panel.

Bail out of sync_state() immediately if the orientation is locked, before
calling read_iio_prox() which updates the curr_orientation value.
There are 2 reasons for this change:
1. Currently meta-monitor-config-manager.c always assumes normal / upright
orientation when generating a new config. This means that e.g. when an
external monitor gets plugged in the builtin panel's transform will be reset
to normal / upright even if the device is not in an upright orientation.
To fix this meta-monitor-config-manager.c needs to call
meta_orientation_manager_get_orientation() to get the current orientation
when generating a new config. Without this change locking the orientation
would stop the emitting of "orientation-changed" signals but we would
still update the curr_orientation value. So when a new config needs to
be generated the latest orientation would be used, effectively ignoring
the "orientation-lock" setting, not updating curr_orientation when
locked fixes this.
2. This ensures we properly emit an an "orientation-changed" signal when
the orientation has changed between when it was locked and it was
unlocked. Before this change if the user locked the orientation, changed it
and then unlocked it, no signal would be raised as we would already have
updated the curr_orientation value turning the sync_state() call in
orientation_lock_changed() into a no-op.

Using `-Dnative_backend=false` caused build failure due to a missing
(implicit) definition of `META_IS_BACKEND_X11`. But if we define it
properly then that just leaves some of the function's locals uninitialized
and it will never work anyway. Just return unconditionally if there's no
native backend to initialize the variables.

Scaling the `monitor_area` before texture creation was just wasting
megabytes of memory on resolution that the monitor can't display. This
was also hurting runtime performance.
Example:
Monitor is natively 1920x1080 and scale set to 3.
Before: The monitor texture allocated was 5760x3250x4 = 74.6 MB
After: The monitor texture allocated is 1920x1080x4 = 8.3 MB

When creating a virtual device for the native backend, no "device-added"
is emitted.
Similarly, no "device-removed" signal is emitted either when the virtual
device is disposed.
However, the backend plugs into the "device-added" signal to set the
monitor device. Without the "device-added" signal being emitted, the
monitor associated with a virtual device remains NULL.
That later will cause a crash in `meta_idle_monitor_reset_idlettime()`
called from `handle_idletime_for_event()` when processing events from a
virtual device because the device monitor is NULL.
Make sure to emit the "device-added" signal when creating a virtual
device, and the "device-removed" when the virtual device is disposed.

When an X11 window requests an initial workspace, we currently trust
it that the workspace actually exists. However dynamic workspaces
make this easy to get wrong for applications: They make it likely
for the number of workspaces to change between application starts,
and if the app blindly applies its saved state on startup, it will
trigger an assertion.
Make sure that we pass valid parameters to set_workspace_state(),
and simply let the workspace assignment fall through to the default
handling otherwise.

Most usually, applications either expose clipboard content either as text
or as images, so the prioritization here is pointless. However there's some
outliers like LibreOffice Calc which exports content as both image and text
formats (besides other internal ones).
In that mixed case, we probably prefer to keep text formats, rather than
image based ones.

The devices_by_id hash table is responsible for managing the reference
to the devices. In remove_device however, for non-core devices there are
additional calls to dispose/unref, after the last reference has
already been dropped by the hash table.

Interoperation between wl_data_device_manager v1 and v3 got broken
at some point. Ensure that we resort to the "copy" action if either
the drop site or the drag source are from a client that requested v1.

MetaX11SelectionOutputStream was storing copies of strings only to use
them in init and then free them in finalize. This was also causing a
small leak, because one of these strings was not freed. Instead of doing
that just don't create these unnecessary copies in the first place.
