ClutterBoxLayout calculates the preferred size of the opposite
orientation (so for example the height if the orientation is horizontal)
by getting the preferred size of the real orientation first, and then
the preferred size of the opposite orientation, using the other size as
for_width/height when doing the request.
Right now, for non-homogeneous layouts this for_width/height does not
adjust for the spacing set on the box layout. This leads to children
being passed a slightly larger for_width/height, which in case of
ClutterText might cause the line to not wrap when it actually should.
This in turn means we can end up with an incorrect preferred size for
the opposite orientation, leading to a wrong allocation.
So fix that and adjust for the spacing just as we do for homogeneous
layouts by subtracting the total spacing from the available size that is
distributed between children.
This fixes the wrong height of the checkbox label reported in
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2574.

41130b08eb added a fix for culling subsurfaces with geometry scale.
Unfortunately it only did so for the opaque regions, not for clip and
unobscured regions, as the effect was hidden by bug that was only
fixed by 3187fe8ebc.
Apply the same fix to clip and unobscured regions and use the chance
to move most of the slightly hackish geometry scale related code
into a single place.
We need to scale slightly differently in the two cases, indicated by
the new `ScalePerspectiveType` enum, as the scale is dependent on the
perspective - once from outside, once from inside of the scaled actor.

The portal API requires a screencast session only for absolution motion
with remote desktop, other methods including relative motion do not
require a screencast session.
There is no reason to be more strict than the API actually is, check for
a screencast session only when required, like for absolute motion events
and touch events.

(cherry picked from commit b8524504f4)
We were setting the pipeline colour to all white (1.0, 1.0, 1.0, 1.0)
and so the default layer combine function multiplied each pixel
(R, G, B, A) by all ones. Obviously multiplying by one four times per
pixel is a waste of effort so we remove the colour setting *and* set
the layer combine function to a trivial shader that will ignore whatever
the current pipeline colour is set to. So now we do **zero** multiplies
per pixel.
On an i7-7700 at UHD 3840x2160 this results in 5% faster render times
and 10% lower power usage (says intel_gpu_top). The benefit is probably
much higher for virtual machines though, as they're no longer being
asked to do CPU-based math on every pixel of a window.

When an app disappears after some data from it has been copied to the
clipboard, the owner of the clipboard selection becomes a new memory
selection source. The initial reference this new selection source is
never unref'ed, which leads to this being leaked on the next clipboard

In commit 4c1fde9d MetaCullable related code was moved out of
MetaShapedTexture into MetaSurfaceActor. While generally desirable,
this removed drawing optimizations in MetaShapedTexture for partial
redraws. The common case for fully obscured actors was still supposed
to work, but it was now discovered that it actually did not.
This commit revert parts of 4c1fde9d: it reintroduces clipping
to MetaShapedTexture but leaves all culling and actor related logic
in MetaSurfaceActor.

The size of the buffer the texture will be written to by
paint_to_buffer() is determined based on
meta_screen_cast_area_stream_src_get_specs() which uses roundf() to
calculate the width and height after scaling. Because the size of the
texture to be written to that buffer is calculated using ceilf(), it
might exceed the allocated buffer when using fractional scaling.
In 3.36 paint_to_buffer() is used from capture_view() which also uses
roundf() to allocate its buffer. Here this leads to a memory corruption
resulting in a crash when taking screenshots of an area.

(cherry picked from commit e216d9c6ad)
When a touch sequence was rejected, we'd update the event timestamps of
incoming touch events to help with implementing grabs. This was done by
sending a ClientMessage with a counter, and comparing the counter to
decide whether we're seing a replayed event or not.
This had the unforseen consequence that we would potentially end up
destroying all actors including the stage, since, when mutter receives a
ClientMessage event, it would assume that it's a WM_PROTOCOLS event, and
handle it as such. The problem with this approach is that it would
ignore fact that there might be other ClientMessage types sent to it,
for example the touch synchronization one. What could happen is that the
touch count value would match up with the value of the WM_DELETE_WINDOW
atom, clutter would treat this as WM_PROTOCOLS:WM_DELETE_WINDOW, which
it'd translate to clutter_actor_destroy(stage).
Destroying the stage in such a way is not expected, and caused wierd
crashes in different places depending on what was going on.
This commit make sure we only treat WM_PROTOCOLS client messages as
WM_PROTOCOLS client messages effectively avoiding the issue.
This fixes crashes such as:

This cannot be made to work reliably. Some factoids:
- Internal devices may be connected via USB.
- The ACPI spec provides the _PLD (Physical location of device) hook to
determine how is an USB device connected, with an anecdotal success
rate. Internal devices may be seen as external and vice-versa, there is
also an "unknown" value that is widely used.
- There may be non-USB keyboards, the old "AT Translated Set 2 Keyboard"
interface does not change on hotplugging.
- Libinput has an internal series of quirks to classify keyboards as
internal of external, also with an "unknown" value.
These heuristics are kinda hopeless to get right by our own hand. Drop
this external keyboard detection in the hope that there will be something
more deterministic to rely on in the future (e.g. the libinput quirks
made available to us directly or indirectly).

We're iterating inside the PipeWire loop when detecting PipeWire errors,

the objects, including the src and the associated PipeWire objects, but

In the native backend, the MetaRenderer manages the view by creating one
per CRTC, but until now the MetaStageX11 managed the view for the X11
backend. This caused some issues as it meant meta_renderer_get_views()
not returning anything, and that the view of the X11 screen not being a
MetaRendererView, while in the other backends, all views are.
Fix this by moving the view management responsibility to
MetaRendererX11Cm, and have MetaStageX11 only operate on it via
meta_renderer_x11_cm_*() API. The MetaRendererX11Cm takes care of making
sure the view is always added to the list in the renderer, and turning
X11 screen sizes into "layouts" etc.

It was removed in 3.34 as part of 6ed5d2e2. And we thought that was the

in 3.36 seems to suggest otherwise.
We don't know what or where the offending thread is, but since:
1. We used XInitThreads for years already prior to 3.34; and
2. Extensions or any change to mutter/gnome-shell could conceivably use
threads to make X calls, directly or indirectly,
it's probably a good idea to reintroduce XInitThreads. The failing assertion
in libx11 is also accompanied by a strong hint:

These phase callbacks are not intended to be inovked when something

Either onto a framebuffer, or into a CPU memory buffer. The latter will
use an former API and then copy the result to CPU memory. The former
allocates an offscreen framebuffer, sets up the relevant framebuffer
matrices and paints part of the stage defined by the passed rectangle.
This will be used by a RecordArea screen cast API. The former to paint
directly onto PipeWire handled dma-buf framebuffers, and the latter for
PipeWire handled shared memory buffers.

If there is a paint context available (i.e. for the phases that are

The redraw clip that's painted together with the damage region has to be
copied earlier than we do right now. That's because if
PAINT_DAMAGE_REGION is enabled, buffer age is disabled and thus
use_clipped_redraw is FALSE. That means the redraw_clip is updated and
set to the full view-rect. If we copy the queued_redraw_clip after that,
it's also going to be set to the full view-rect. So copy the redraw clip
a bit earlier to make sure we're actually passing the real redraw clip
to paint_damage_region().
Also keep the queued_redraw_clip around a bit longer so it can actually
be used by paint_damage_region() and isn't freed before that.
While at it, move paint_damage_region() from swap_framebuffer() into
clutter_stage_cogl_redraw_view() so we don't have to pass things to
swap_framebuffer() only for debugging.

When resizing an X11 window with client side decorations, the shadow is
clipped by the frame bounds so that we don't need to paint the shadow
under the opaque areas covered by the window and its frame.
When the X11 client uses the EMWH synchronization mechanism (like all
gtk-3 based clients), the actual window may not be updated so that the
actual window and it frame may be behind the expected window frame
bounds, which gives the impression of de-synchronized shadows.
To avoid the issue, keep a copy of the frame bounds as a cache and only
update it when the client is not frozen so that the clipping occurs on
the actual content.

If drmModePageFlip() or custom_page_flip_func fails, process_page_flip() was
forgetting to undo the ref taken for that call. This would leak page_flip_data.
The reference counting works like this:
- when created, ref count is 1
- when calling drmModePageFlip, ref count is increased to 2
- new: if flip failed, ref count is decreased back to 1
- if calling schedule_retry_page_flip(), it takes a ref internally
- if calling mode_set_fallback(), it takes a ref internally
- all return FALSE paths have an explicit unref
- return TRUE path has an explicit unref
This issue was found by code inspection and while debugging an unrelated issue
with debug prints sprinkled around. I am not aware of any end-user visible
issues being fixed by this, as the leak is small and probably very rare.

When testing a laptop with intel and DisplayLink devices, attempting to set the
DL output as the only active output resulted in GNOME/Wayland freezing. The
main event loop was running fine, but nothing on screen would get updated once
the DL output become the only one. This patch fixes that issue.
DisplayLink USB 3 devices use an out-of-tree kernel DRM driver called EVDI.
EVDI can sometimes fail drmModePageFlip(). For me, the flip fails reliably when
hotplugging the DL dock and when changing display configuration to DL only.
Mutter has a workaround for failing flips, it just calls drmModeSetCrtc() and
that succeeds.
What does not work reliably in the fallback path is Mutter keeping track of the
pageflip. Since drmModePageFlip() failed, there will not be a pageflip event
coming and instead Mutter queues a callback in its stead. When you have more
than one output, some other output repainting will attempt to swap buffers and
calls wait_for_pending_flips() which has the side-effect of dispatching any
queued flip callbacks. With multiple outputs, you don't get stuck (unless they
all fail the exact same way at the same time?). When you have only one output,
it cannot proceed to repaint and buffer swap because the pageflip is not marked
complete yet. Nothing dispatches the flip callback, leading to the freeze.
The flip callback is intended to be an idle callback, implemented with a
GSource. It is supposed to be called as soon as execution returns to the main
event loop. The setup of the GSource is incomplete, so it will never dispatch.
Fix the GSource setup by setting its ready-time to be always in the past. That
gets it dispatched on the next cycle of the main event loop. This is now the
default behavior for all sources created by meta_kms_add_source_in_impl().
Sources that need a delay continue to do that by overriding the ready-time
explicitly.
An alternative solution could have been to implement GSource prepare and check
callbacks returning TRUE. However, since meta_kms_add_source_in_impl() is used
by flip retry code as well, and that code needs a delay through the ready-time,
I was afraid I might break the flip retry code. Hence I decided to use
ready-time instead.

According to the XSetSelectionOwner libX11 documentation:
[...] If the owner window it has specified in the request is later
destroyed, the owner of the selection automatically reverts to None,
but the last-change time is not affected.
This is indeed visible through the selection_timestamp field in
XFixesSelectionNotify events.
Use this to check whether the selection time is recent-ish (thus
likely coming from an explicit XSetSelectionOwner request) and honor
the client intent by setting a "NULL" owner. If the selection time
is too old, it's definitely an indication of the owner client being
closed, the scenario where we do want the clipboard manager to take
over.
This fixes two usecases:
- X11 LibreOffice / WPS clear the selection each time before copying
its own content. Mutter's clipboard manager would see each of those
as a hint to take over, competing with the client over selection
ownership. This would simply no longer happen
- Password managers may want to clear the selection, which would be
frustrated by our clipboard manager.
There's a slight window of opportunity for the heuristics to fail

would miss the clipboard manager taking over.

Most visible with xwayland-on-demand, at the time of setting things up

Flushing the X11 selection output stream may happen synchronously or

(cherry picked from commit 1909977a67)
If a write_async() comes up while we are flushing on the background,
the task will be queued, but not deemed a reason on itself to keep
flushing (and finish the task) after a property delete event.
To fix this, do not ever queue up write_async tasks (this leaves
priv->pending_task only used for flush(), so the "flush to end"
behavior in the background is consistent). We only start a
background flush if there's reasons to do it, but the tasks are
immediately finished.
All data will still be ensured to be transfered on flush/close,
this makes the caller in this situation still able to reach to it.

When closing the lid of a laptop, we reconfigure all the monitors in order
to update the CRTCs and (if enabled) the global UI scaling factor.
To do this, we try first to reuse the current configuration for the usable
monitors, but if we have only monitor enabled and this one is on the laptop
lid we just end up creating a new configuration where the primary monitor is
the laptop one (as per find_primary_monitor() in MetaMonitorConfigManager),
but ignoring the user parameters.
In case the user selected a different resolution / scaling compared to the
default one, while the laptop lid is closed we might change the monitors
layout, causing applications to rescale or reposition.
To avoid this, when creating the monitors configuration from the current
current state, in case we have only one monitor available and that one is
the laptop panel, let's just reuse this configuration.

The CRTC level transform (not necessarily the hw transform) must be

The port to per CRTC views was incomplete; we still used the logical
monitor layout as the stage view layout, while still using one view per
CRTC.
This worked fine for most cases, e.g. regular monitors, tiled or
non-tiled, transformed or non-transformed. Where it broke, however, was
when a monitor consists of multiple CRTCs. We already have the layout a
CRTC corresponds to on the stage kept with the CRTC metadata, so use
this directly.
Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1170https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1199`
The CRTC level transform (i.e. not necessarily the one set on the
hardware) is what is relevant for calculating the layout the CRTC will
have on the stage, so only use the one that can be handled by the
hardware for the CRTC assignment.
This makes the CRTC layout valid for tiled monitors.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1199
Previously the tile coordinate was used to offset a CRTC scanout
coordinate within a larger framebuffer. Since 3.36 we're always
scanning out from (0, 0) as we always have one framebuffer per CRTC; we
instead use the tile coordinate to calculate the coordinate the tile has
in the stage view. Adapt calculation to fulfil this promise instead of
the old one.
This also corrects the tiled custom monitor test case.

On VT switch, the devices are removed, which means for Wayland disabling

(cherry picked from commit f0718c7d95)
With the introduction of "shallow" relayouts, we are now able to enter
allocation cycles not only at the stage but also deeper down the
hierarchy if we know an actors allocation isn't affected by its children
since the NO_LAYOUT flag is set.
Now that means when queuing relayouts it's possible that
`priv->needs_allocation` gets set to TRUE for some actors down the
hierarchy, but not for actors higher up in the hierarchy. An actor tree
where that happens could look like that:
stage -> container -> container2 (NO_LAYOUT) -> textActor
With that tree, if the "textActor" queues a relayout, "container2" will
be added to the relayout hashtable of the stage and the actors "stage"
and "container" will have `priv->needs_allocation` set to FALSE.
Now if another relayout on the stage actor is queued,
`clutter_stage_queue_actor_relayout()` currently removes all the other
hashtable entries in favour of the stage entry, (wrongly) assuming that
will allocate everything. It doesn't allocate everything because in the
example above "container" has `priv->needs_allocation` set to FALSE,
which makes clutter_actor_allocate() return early before allocating its
children, so in the end "container2" will never get a new allocation.
To fix this, stop flushing the relayout hashtable when queuing a
stage-relayout and still add new entries to the hashtable if a stage
relayout is already queued to make sure we still go through all the
previously queued "shallow" relayouts. That shouldn't hurt performance,
too, because as soon as an actor got allocated once, it doesn't need an
allocation anymore and should bail out in clutter_actor_allocate() as
long as it's absolute position didn't change.

Currently we check whether a window is alive everytime it's focused.
This means that an application that doesn't respond to the check-alive
event during startup always showing the "application froze" dialog,
without the user ever trying to interact with it.
An example where this tends to to happen is with games, and for this
particular scenario, it's purely an annoyance, as I never tried to
interact with the game window in the first place, so I don't care that
it's not responding - it's loading.
To avoid these unnecessary particular "app-is-frozen" popups, remove the
alive check from the focus function, and instead move it back to the
"meta_window_activate_full()" call. To also trigger it slightly more
often, also add it to the path that triggers the window focus when a
user actively clicks on the window.
This means that we currently check whether a window is alive on:
* Any time the window is activated. This means e.g. alt-tab or
selecting the window in the overview.
* The user clicks on the window.
Note that the second only works for an already focused window on
Wayland, as on X11, we don't refocus it. This particular case isn't
changed with this commit, as we didn't call meta_window_focus() to begin
with here.

It isn't immediately obvious that this is impossible, because there's some

(cherry picked from commit 37eda498f2)
Previously clutter timelines advanced according to `g_source_get_time`.
But that meant the spatial stepping of animations was visibly sensitive to
any irregularities in the main loop. It also represented a time older [1]
than the intended presentation time of each frame.
Now we instead use `master_clock_get_next_presentation_time`. This ensures
we get the smoothness of hardware vsync as well as being closer to the
actual presentation time.
This means, for example, backends like Xorg that move the hardware cursor
independently of repaints will have their animations more closely matching
the hardware cursor position. So the cursor appears to stick more closely
when dragging windows or on the lock screen etc.

Normally we bail out in `sync_actor_geometry()`. The comment there
states:
```
Normally we want freezing a window to also freeze its position; this allows
windows to atomically move and resize together, either under app control,
or because the user is resizing from the left/top. But on initial placement
we need to assign a position, since immediately after the window
is shown, the map effect will go into effect and prevent further geometry
updates.
```
The signal for the initial sync originates in `MetaWindow` though and predates
`xdg_toplevel_set_maximized`, which again calls `meta_window_force_placement`,
triggering the signal too early. As a result, Wayland clients that start up
maximized have a wrong map animation, starting in the top-left corner.
In order to fix this without changing big parts of the geometry logic and risking
regressions, force the initial sync again before mapping.

IBusInputContext/ClutterInputFocus/GtkIMContext all go for offset+len
for their ::delete-surrounding signals, with offset being a signed int
(neg. to delete towards left of selection, pos. to delete towards right
of selection) and len being an unsigned int from the offset (and
presumably, skipping the current selection).
The text-input protocols however pass in this event two unsigned integers,
one being the length of text to delete towards the left of the selection,
and another the length of text to delete towards the right of the selection.
To translate properly these semantics, positive offsets shouldn't account
for before_length, and negative offset+len shouldn't account for after_length.
The offset/length approach may of course represent deletions that are
detached from the current cursor/selection, we simply delete the whole range
from the cursor/selection positions then.

The input method can assign a negative value to

Fix a regression that got introduced with
c483b52d24 where we started passing the
redraw_clip to paint_stage() instead of creating a temporary view_region
for unclipped redraws: In case we detect an invalid buffer age, we fall
back to doing an unclipped redraw after we passed the first check
setting up may_use_clipped_redraw. That means we didn't reset the
redraw_clip to the view_rect, and we're now going to redraw the stage
using the original redraw clip even though we're swapping the full
framebuffer without damage.
To fix that, check for the buffer age before setting up the
fb_clip_region and the redraw_clip and set may_use_clipped_redraw to
FALSE if the buffer age is invalid, too. This ensures the redraw_clip is
always going to be correctly set to the view rect when we want to force
a full redraw.

Cogl shares some GL functions between the GLES and the big

their prototypes are in cogl-util-gl-private.h, they're actually
implemented inside cogl-driver-gl.c, which is strictly only
about the big GL driver.

The transactional KMS API has been modelled after atomic KMS. Atomic KMS
currently doesn't support forwarding cursor hotspot metadata, thus it
was left out of the transactional KMS API having the user set the simply
create a plane assigment with the cursor sprite assigned to a cursor
plane using regular coordinates.
This, however, proved to be inadequate for virtual machines using
"seamless mouse mode" where they rely on the cursor position to
correspond to the actual cursor position of the virtual machine, not the
cursor plane. In effect, this caused cursor positions to look "shifted".
Fix this by adding back the hotspot metadata, right now as a optional
field to the plane assignment. In the legacy KMS implementation, this is
translated into drmModeSetCursor2() just as before, while still falling
back to drmModeSetCursor() with the plane coordinates, if either there
was no hotspot set, or if drmModeSetCursor2() failed.
Eventually, the atomic KMS API will learn about hotspots, but when
adding our own atomic KMS backend to the transacitonal KMS API, we must
until then still fall back to legacy KMS for virtual machines.

When calculating the resource scale of a clone source, we might end up
in situations where we fail to do so, even though we're in a paint. A
real world example when this may happen if this happens:
* A client creates a toplevel window
* A client creates a modal dialog for said toplevel window
* Said client commits a buffer to the modal before the toplevel
If GNOME Shell is in overview mode, the window group is hidden, and the
toplevel window actor is hidden. When the clone tries to paint, it fails
to calculate the resource scale, as the parent of the parent (window
group) is not currently mapped. It would have succeeded if only the
clone source was unmapped, as it deals with the unmapped actor painting
by setting intermediate state while painting, but this does not work
when the *parent* of the source is unmapped as well.
Fix this by inheriting the unmapped clone paint even when calculating
the resource scale.
This also adds a test case that mimics the sequence of events otherwise
triggered by a client. We can't add a Wayland client to test this, where
we actually crash is in the offscreen redirect effect used by the window

For HiDPI pointer cursors backed by Wayland surfaces, the hotspot must
be placed using integers on the logical pixel grid. In practice what
this means is that if the client loads a cursor sprite with the buffer
scale 2, and it's hotspot is not dividable by 2, it will be rounded
down to an integer that can. E.g. a wl_surface with buffer scale 2 and a
cursor image with hotspot coordinate (7, 7) will have the coordinate
(3.5, 3.5) in surface coordinate space, and will in practice be rounded
down to (3, 3) as the hotspot position in wl_pointer only takes
integers.
To not potentially shift by 1 pixel on HiDPI monitors when switching
between wl_surface backend cursor sprites and built-in ones, make the
built in one emulate the restrictions put up by the Wayland protocol.
This also initializes the theme scale of the xcursor sprite instances to
1, as they may not have been set prior to being used, it'll only happen
in response to "prepare-at" signals being emitted prior to rendering.

would draw a texture scaled, as e.g. a 200x200 sized texture with buffer
scale 2 would have the size 100x100. When stage views were not scaled,
we'd apply a geometry scale meaning it'd end up as 200x200 anyway, thus
pass the check, but when stage views are scaled, it'd still be painted
as a 100x100 shaped texture on the stage, thus failing the
are-we-unscaled test.
Fix this by comparing the transformed paint size with the sampled size,
instead of the paint size again, when checking whether we are being
painted scaled or not. For example, when stage views are scaled, our
200x200 buffer with buffer scale 2, thus content size 100x100 will
transform to a 200x200 paint command, thus passing the test. For
non-scaled stage views, our 200x200 buffer with buffer scale 2 thus
content size 100x100 will also transform into a 200x200 paint command,
and will also pass the check, as the texture sample region is still
200x200.

A user may have configured an output to be panning, e.g. using xrandr
--output <output> --mode <mode> --panning <size>. Respect this by making
the logical monitor use the panning size, instead of the mode. This
makes e.g. makes the background cover the whole panning size, and panels
etc will cover the whole top of the panned area, instead of just the top
left part covering the monitor if having panned to (0, 0).
No support is added to configuring panning, i.e. a panned monitor
configuration cannot be stored in monitors.xml.

Just like libmutter-clutter, and libmutter, mark exported symbols with
an COGL_EXPORT macro. This removes the .map and .map.in files previously
used, containing a list of semi private symbols. This symbol was out of
date, i.e. pointed to non-existing symbols, and was also replaced with
COGL_EXPORT macros.
unit_test_* symbols are exported by the help of the unit test defining
macro. test_* symbols are no longer supported as it proved unnecessary.

This is so that cogl-trace.h can start using things from cogl-macros.h,

no practical reason why we shouldn't just include cogl-trace.h via
cogl.h as we do with everything else.

The upper layers (OSDs basically) want to know the monitor that a
tablet is currently assigned to, not the monitor just as configured
through settings.
This broke proper OSD positioning for display-attached tablets since
commit 87858a4e01, as the MetaInputMapper kicks in precisely when
there is no configured monitor for the given device.
Consulting both about the assigned output will make OSDs pop up
again in the right place.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/971
We used to inhibit all pad actions while the OSD is shown, but one we
would actually want to handle are mode switches while the OSD is open.
So it has an opportunity to catch up to the mode switch.
This lets MetaInputSettings reflect the mode switch (eg. when querying
action labels), so the OSD has an opportunity to update the current
actions.

Commit cda9579034 fixed a corner case when setting the initial workspace
state of transient windows, but it still missed a case:
should_be_on_all_workspaces() returns whether the window should be on all
workspaces according to its properties/placement, but it doesn't take
transient relations into account.
That means in case of nested transients, we can still fail the assert:
1. on-all-workspaces toplevel
2. should_be_on_all_workspaces() is TRUE for the first transient's parent,
as the window from (1) has on_all_workspaces_requested == TRUE
3. should_be_on_all_workspaces() is FALSE for the second transient's
parent, as the window from (2) is only on-all-workspace because
of its parent
We can fix this by either using the state from the root ancestor
instead of the direct transient parent, or by using the parent's
on_all_workspaces_state.
The latter is simpler, so go with that.

This class sits between ClutterInputDevice and the backend implementations,
it will be the despositary of features we need across both backends, but
don't need to offer through Clutter's API.
As a first thing to have there, add a getter for a WacomDevice. This is
something scattered across and somewhat inconsistent (eg. different places
of the code create wacom devices for different device types). Just make it
here for all devices, so users can pick.

Most people just see a harmless warning when applying this setting to
all touchpads (which this patch fixes). But tap[-and-drag] is supposed
to remain enabled for display-less Wacom tablets, despite configuration

Fix this by using the mapping function, so the setting is forced on for
wacom devices. This happens on a per-device basis, so the warning is
gone too.

This fixes a case that was overlooked in
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1036 - when we
have a geometry scale > 1 and Wayland subsurfaces that have an offset
to their parent surface (which is often the case when the toplevel surface
includes decoration/shadows etc.), we have to add extra offset to their
opaque regions so they match their 'visible' location.
This is necessary as `meta_cullable_cull_out_children` moves the coordinate
system during culling, but does not know about geometry scale.
Also, remove the redundant check for `window_actor` - we only hit this code
path if a `window_actor` culls out its children.

Some tablets like the Cintiq 24HDT have several mode switch buttons
per group. Those are meant to jump straight to a given mode, however
we just handle cycling across modes (as most other tablets have a
single mode switch button per group).
So spice up the mode switch handling so we handle multiple mode
switch buttons, assigning each of them a mode. If the device only
has one mode switch button, we do the old-fashioned cycling.

When a page flip fails with a certain error code, we've treated this as
a hint that page flipping is broken and we should try to use mode
setting instead.
On some drivers, it seems that this error is also reported when there
was no mode set, which means we'll have no cached mode set to use in the
fallback. The lack of prior mode set tends to happen when we hit a race
when the DRM objects change before we have the time to process a hotplug
event.
Handle the lack a missing mode set in the flip fallback path, with the
assumption that we'll get a hotplug event that'll fix things up for us
eventually.

We send configure events for state changes e.g. for `appears-focused`,
etc. What we don't want to do is to do this for popup windows, as in
Wayland don't care about this state.
When the focus mode was configured to "sloppy focus" we'd get
`appears-focused` state changes for the popup window only by moving the
mouse cursor around, and while a popup may care about focus, it does not
care about related appearance, as there is no such state in xdg_popup.
What these state changes instead resulted in was absolute window
configuration events, intended for toplevel (xdg_toplevel) windows. In
the end this caused the popup to be positioned aginst at (0, 0) of the
parent window, as the assumptions when the configuration of the popup
was acknowledged is that it had received a relative position window
configuration.
Fix this by simply ignoring any state changes of the window if it is a
popup, meaning we won't send any configuration events intended for
toplevels for state changes. Currently we don't have any way to know
this other than checking whether it has a placement rule. Cleaning up
MetaWindow creation is left to be dealt with another day.

If the CRTCs the cursor is visible on do not share a common scale
and transform, we can't use the cursor hardware plane as we only have one.
We therefore fall back to software / gl cursor.
The check for that currently happens after we tried to upload the cursor image
to the hardware plane though.
This is made worse by the fact that in the scaling step, where we scale the
cursor image to the desired size, until now we expected a valid common scale -
otherwise scaling the image by an uninitialized float.
Make sure we bail out early during the scale/upload step if we don't have common
scales and transforms - to avoid that bug and save some unnecessary work.

Make sure it is only the special modifier (hardcoded to 1 currently)
which is being pressed (not counting locked modifiers) before notifying
that the special modifier is pressed, as we are interested in it being
pressed alone and not in combination with other modifier keys.
This helps in two ways:
- Pressing alt, then ctrl, then releasing both won't trigger the locate
pointer action.
- Pressing alt, then ctrl, then down/up to switch workspace won't interpret
the last up/down keypress as an additional key on top of the special ctrl
modifier, thus won't be forwarded down to the focused client in the last
second.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/812https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1014
If you first press a key that triggers the "special modifier key" paths
(ctrl, super), and then press another key that doesn't match (yet?) any
keybindings (eg. ctrl+alt, super+x), the second key press goes twice
through process_event(), once in the processing of this so far special
combination and another while we let the event through.
In order to keep things consistent, handle it differently depending on
whether we are a wayland compositor or not. For X11, consider the event
handled after the call to process_event() in process_special_modifier_key().
For Wayland, as XIAllowEvents is not the mechanism that allows clients see
the key event, we can just fall through the regular paths, without this
special handling.

For X11 clients running on Wayland, the actual texture is set by
Xwayland.
The shape, input and opaque regions, however are driven by X11
properties meaning that those may come at a different time than the
actual update of the content.
This results in black areas being visible at times on resize with
Xwayland clients.
To make sure we update all the regions at the same time the buffer is
updated, update the shape, input and opaque regions when the texture is
committed from when the Xwayland surface state is synchronized.
That fixes the remaining black areas being sometimes visible when
resizing client-side decorations windows on Xwayland.

For X11 clients running on Xwayland, the opaque, input and shape regions

those regions when needed.

Commit 7dbb4bc3 cached the client area when the client was frozen.
This is not sufficient though, because the buffer size might still be
lagging waiting for the buffer from Xwayland to be committed.
So instead of caching the client size from the expected size, deduce the
client area rectangle from the surface size, like we did for the frame
bounds in commit 1ce933e2.

Listen for GPU hotplug events to initialize their cursor support.
This fixes one reason for why DisplayLink devices may not be using a hardware

For every stream src, we created and attached a GSource. Upon stream
src destruction, we g_source_destroy():ed the GSource. What
g_source_destroy() does, hawever, is not really "destroy" it but only
detaches it from the main context removing the reference the context had
added for it via g_source_attach(). This caused the GSource to leak,
although in a detached state, as the reference taken on creation was
still held.
Fix this by also removing our own reference to it when finalizing.

If we don't force the placement, we enter the constrain machinery with
the position (0, 0), meaning we always get the "current work area" setup

"window->calc_placement" to TRUE while move-resizing, causing the
move-resize to first calculate the initial position.

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.

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

configuration while there is an active resize grab.

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.

If a opaque region is explicitly set we should not consider the surface

We need the stencil buffer to consist of binary values of 0 and 1

When using a region clip and something has a rectangle clip pushed, a
special drawing method for ClutterTexts (emit_vertex_buffer_geometry()
in cogl-pango-display-list.c) starts to fail and clipping issues with
long texts (because emit_vertex_buffer_geometry() is only used for texts
longer than 25 characters) start to appear. This specifically happened
in Looking Glass, where the StViewport of the ScrollView sets a
rectangle clips and the texts are usually longer than 25 characters.
This is caused by the changing of the perspective and modelview matrix
when drawing to the stencil buffer and started happening when
region-clipping was introduced with commit 8598b654. Even though the
changing of the matrices was done before that, too, the issue probably
didn't happen because `rect->can_be_scissor` was TRUE and no stencil
buffer clipping was used at all.
To fix this, temporarily save the old matrices, then set the new ones
and restore the old ones when we're done drawing to the stencil buffer.

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.

Even though cogl_framebuffer_flush() was supposed to be enough,

This is a winsys-specific API that allows exporting a DMA buffer fd.

In future patches, we'll create additional CoglFramebuffers that
will be shared via DMA-Buf with PipeWire. When recording frames,
we'll blit the current onscreen framebuffer into the shared one.
However, that presents a problem: cogl_framebuffer_blit() mimics
glBlitFramebuffer() semantics, and doesn't do an implicit flush
of the GPU command stream. As a consequence, clients may receive
unblitted or incomplete framebuffers.
We could use cogl_framebuffer_finish() to ensure the commands were
submitted to the GPU, but it is too harsh -- it blocks the CPU
completely until the commands are finished!
Add cogl_framebuffer_flush(), which ensures the command stream is
submitted to the GPU without blocking the CPU. Even though we don't
use the framebuffer specifically, it may be useful in the future
for e.g. a potential Vulkan backend to have access to the framebuffer.

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
right after creation (to let input devices be known), so those device
additions would trigger the touch-mode checks.
Creating it in advance results in checks being correctly performed, although
redundantly.

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.

This adds a new frameclock tracing mark for a single cycle of the frame
clock. Doing so allows Sysprof to potentially do more with the information
that happens during the frameclock. For example, we can now find
allocations that happen while the frame clock is advancing.

The stage window handled the redraw clip in a global manner; this would
interfere if we want to paint views individually as it'd mean
intersecting views (i.e. mirrored monitors) would loose the redraw clip
once the first view was painted. It also is awkward to have a global
state for something that is built up before redrawing, and only really
valid during paint, due to buffer damage history.
This commits removes all redraw clip management from the stage window,
moving it all into the stage views. When a redraw clip is added to the
stage, every affected view will get the same redraw clip added to it,
and eventually when painted, the stage window (ClutterStageCogl) will
retrieve the redraw clip for each view as it repaints them.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1042
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).

Add a helper that scales and clamps a region, aimed to be used when
transforming between framebuffer coordinate space and view coordinate
spaces.
This helps readability by moving out the verbose for loops that deals
with the individual rects of a region to the helper, making the logic
where it's used much simpler.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1042
The 'have_clip' variable has repeatedly confused me to meaning that
there is a clip. What it actually means is that the effective clip
covers the whole view; the 'redraw_clip == NULL' meaning full redraw is
an important implementation detail for the context, and makes the
intention of the variable unclear; especially since we will after a
couple of blocks will *always* have a clip, just that it covers the
whole view.
Rename the variable to 'is_full_redraw' and negate the meaning, aiming
to make things a lot more clear.

When calculating the fallback framebuffer clip region, which should be
the region in framebuffer coordinates, we didn't scale the view layout
with the view framebuffer scale, meaning for any other scale than 1,
we'd draw a too small region of the view. Fix this by just using the
size of the framebuffer directly, avoiding any scale dependent
calculation all together.

We'll expect a swap event if any of the view paints resulted in a swap;

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.

This only needs to be initialized once but is in the hot path of creating
new paint nodes (for which we create many). Instead, do this as part of

When calculating regions, a lot of temporary allocations are created. For
the array of rects (which is often a short number of them) we can use
stack allocations up to 1 page (256 cairo_rectangle_int_t). For building
a region of rectangles, cairo and pixman are much faster if you have all
of the rectangles up front or else it mallocs quite a bit of temporary
memory.
If we re-use the cairo_rectangle_int_t array we've already allocated (and
preferably on the stack), we can delay the creation of regions until after
the tight loop.
Additionally, it requires fewer allocations to union two cairo_region_t
than to incrementally union the rectangles into the region.

g_signal_emit_by_name() is used to emit signals on ClutterContainer when

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.

Add API to ClutterSeat that allows inhibiting the unsetting of the

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.

Which offscreens actor rendering only in cases where it hasn't changed for

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
pings to the window, instead we should just wait for that answer or

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
error that should never happen, so check every timestamp before sending
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.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/891
Increase the number of checks whether a window is still responsive and
ping windows on every call to `meta_window_focus()` instead of
`meta_window_activate_full()`. This ensures the window is also pinged in
case normal interaction like clicks on the window happen and a close
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

So instead of trying to compute the scale factor by which the given
clipping bounds need to be adjusted, simply clip the resulting image
based on the given bounds to make sure we never overflow the destination
buffer.

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
even after `xdg_surface.get_toplevel` is invoked.

Modify create_for_builtin_display_rotation to lookup the
MetaLogicalMonitorConfig for the panel in the logical_monitor_configs
list instead of only working when there is only 1 monitor.
The goal of this change is to honor accelerometer value changes when there is
more than 1 monitor.
Note, since create_for_builtin_display_rotation is also used for handling the
"rotate-monitor" hotkey and this commit modifies the common path of
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.

When creating a new config because of a monitor being (un)plugged or

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

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.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/1025
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

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

e9fbbd5853 changed meta_backend_get_idle_monitor() to use

If an actor sets flag `CLUTTER_ACTOR_NO_LAYOUT` then that means it
is (or should be) unaffected by `queue_relayout` calls in its children.
So we can avoid propagating `queue_relayout` all the way up to the stage
and avoid a full stage relayout each time.
But those children whose parent has `CLUTTER_ACTOR_NO_LAYOUT` still need
to be allocated at some point. So we do it at the same point where it
happened before. Only we now queue a *shallow* relayout so the `allocate`
run on the next frame doesn't need to descend the whole actor tree anymore.
Only a subtree and hopefully very small.
For free-floating and top-level actors this provides a measurable
performance benefit. According to Google Profiler, calls to
`_clutter_stage_maybe_relayout` are now so cheap that they no longer show
up in performance profiles.

The meta_seat_native_constrain_pointer() function receives the current
pointer position, and the new pointer position as in/out parameters.
We were however calculating the new coordinates based on the last pointer
position if there was no pointer constrain in place.
Fortunately to us, this didn't use to happen often/ever, as a pointer
constrain function is set on MetaBackend initialization. This behavior
did also exist previously in MetaDeviceManagerNative.

The backend being initialized triggers a pointer warp (and motion event)
where we want to observe the callbacks put in place. So ensure we set

Just go ATM through backend checks, and looking up directly the
native event data, pretty much like the rest of the places do that...
Eventually would be nice to have this information in ClutterEvent,
but let's not have it clutter the MetaBackend class.

This is unlikely to happen, and unlikely to be right (eg. we don't translate
input event coordinates, since those are not in display coordinate space, we
don't offer any feedback for those either).
This can simply be dropped, we listen to XIAllMasterDevices, which suffices
for what we want to do.

When a Wayland window is mapped or unmapped, the Wayland compositor is
expected to send the coorespoindign `wl_pointer` enter/leave events to
the affected clients.
To do so, mutter calls `meta_wayland_compositor_repick()` which
eventually calls `meta_wayland_pointer_repick()` and
`repick_for_event()`.
If pointer input device has not been updated yet, the old clutter actor
is picked and no enter/leave event is emitted.
Make sure we update the pointer input device prior to do the repick to
get the actual `ClutterActor` under the pointer.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/1016https://gitlab.gnome.org/GNOME/mutter/merge_requests/1026
The private function `_clutter_input_device_update()` is not currently
exported.
This function calls `_clutter_input_device_set_actor()` which updates
the `ClutterActor` under the pointer, so making that function available
outside of Clutter will allow to make sure the pointer device actor is
updated prior to do picking.
Also, now that the functions is exported to the upper layers, drop the
underscore suffix from the function name.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1026
As we now call `meta_wayland_compositor_repick()` when the effects are
complete for Wayland surfaces, we can safely remove the Wayland specific
code to do the same from `meta_window_show()`.

When mapping/unmapping windows, an animation may be played which can
change the actual actor size and location, hence defeating picking if
done too early.
Make sure we repick when the affects are completed, once the actor is
sized and placed.

When building the frame mask, the current reported frame size may not
match when is actually on screen if the buffer has not been updated
yet.
So instead of getting the frame size from the meta window, deduce it
from the texture size.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1009
Currently, `meta_frame_get_mask()` and `meta_ui_frame_get_mask()` will
return the frame mask applied to the current frame size, by querying the
frame themselves.
To be able to get the frame mask at an arbitrary size, change the API to
take a rectangle representing the size at which the frame mask should be
rendered.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1009
With Xwayland, the shape region is recomputed and reapplied even when
the actor is frozen to prevent the black shadows effect.
However, while recomputing the shape region, the current client size is
taken into account, rather than the size when the client was frozen,
which is ahead of the actual client size using the NET_WM_SYNC protocol.
Keep the current client area and to reuse them when the X11 window actor
is frozen for rebuilding the client mask texture.

Right now the CONTENT_SIZE request mode for a ClutterActor is only
respected by `clutter_actor_get_preferred_size()`, but not by
`get_preferred_width()` and `get_preferred_height()`. Those simply try
to ask the layout manager and will return [0, 0] for actors without
children. So be consistent and also return the content size in those two
functions.

In XDND, we just get a hint on XdndPosition about what's the action

ClutterActors width and height can be reset to automatically use the
preferred (calculated) value by setting the width or height to -1, so

"width" and "height" GObject properties.

Where possible, try to export the buffer rendered by the primary GPU as a
dmabuf and import it to the secondary GPU and turn it into a DRM FB for
scanout. If this works, we get a zero-copy path to secondary GPU outputs.
This is especially useful on virtual drivers like EVDI (used for DisplayLink
devices) which are not picky at all about what kind of FBs they can handle.
The zero-copy path is prioritised after the secondary GPU copy path, which
should avoid regressions for existing working systems. Attempting zero-copy
would have the risk of being less performant than doing the copy on the
secondary GPU. This does not affect the DisplayLink use case, because there is
no GPU in a DisplayLink device.
The zero-copy path is prioritised before the primary GPU and CPU copy paths. It
will be tried on the first frame of an output and the copy path is executed
too. If zero-copy fails, the result from the copy path will take over on that
frame. Furthermore, zero-copy will not be attemped again on that output. If
zero-copy succeeds, the copy path is de-initialized.
Zero-copy is assumed to be always preferable over the primary GPU and CPU copy
paths. Whether this is universally true remains to be seen.
This patch has one unhandled failure mode: if zero-copy path first succeeds and
then fails later, there is no fallback and the output is left frozen or black.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/810
With all the three paths this is quite a handful of code, and it was mostly
duplicated in two places. A follow-up patch would need to introduce a third
copy of it. Therefore move the code into a helper function.
There are two behavioral changes:
- The format error now prints the string code as well, because it is easy to
read.
- The g_debug() in init_dumb_fb() is removed. Did not seem useful.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/810
There will be another place where I need to release the dumb buffers but not
destroy the whole secondary_gpu_state, so extract this bit of code into a
helper.
The checks of fb_id are dropped as redundant with the check already in in
release_dumb_fb ().
https://gitlab.gnome.org/GNOME/mutter/merge_requests/810
release_dumb_fb () checks 'map' to see if anything needs freeing. Other places
are checking fb_id instead. The checks maybe redundant, but let's reset all
fields here while at it, so that all the checks work as expected.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/810
Simplify the bo freeing functions by not checking what the copy mode is. This
matches what swap_secondary_drm_fb () already does. g_clear_object () is safe
to call even if the value is already NULL.
The copy mode does not change mid-operation. If it did, this change would
ensure we still clean up everything. So this is more future-proof too.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/810
To mirror what happens in meta_onscreen_native_swap_buffers_with_damage(), warn
here too if next_fb is not NULL. This makes it clear to the reader of what the
expectations are inside this function.
Ensuring next_fb is NULL as the first thing in the function will make all error
paths equal: no longer some failures reset next_fb while others don't. Removing
such special cases should reduce surprises.

Just pass it in to the vertex shader like in GLES, it's one less thing
to vary between drivers. mutter is, shall we say, not a heavy user of
point primitives, so any performance impact (it might be measurable, who
knows) is not an issue. Again, the feature flag remains to be cleaned up
in a future commit.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/995
We're always running through the GLSL pipeline so the fixed-function
alpha test is never invoked. This change does not yet remove the
alpha-test feture bit from the context because this bit of uniform
handling is going to be simplified in a future commit.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/995
If we end up trying to do a mode set on a DRM state that has already
changed behind our back without us yet having seen the hotplug event we
may fail with `EINVAL`. Since the renderer layer doesn't handle mode set
failure, it'll still try to page flip later on, which will then also
fail. When failing, it'll try to look up the cached mode set in order to
retry the mode set later on, as is needed to handle other error
conditions. However, if the mode set prior to the page flip failed, we
won't cache the mode set, and the page flip error handling code will get
confused.
Instead of asserting that a page flip always has a valid cached mode set
ready to look up, handle it being missing more gracefully by failing to
mode set. It is expected that things will correct themself as there
should be a hotplug event waiting around the the corner, to reconfigure
the monitor configuration setting new modes.

On Xwayland, freezing actor updates on sync requests means the
server-side frame and shadows repaint will be frozen as well, which
causes the shadow to show black at times when resizing X11 clients
which support NET_WM_SYNC.
Using freeze/thaw commits prevents the content from changing, yet the
shape window still needs to be updated when frozen otherwise the
difference in shape induced by the on-going resize operation will show
as well, even if the toplevel window has its commits frozen.

Closes: https://gitlab.gnome.org/GNOME/mutter/issues/858
To address the black shadows that sometimes show during resize with
Xwayland, we need to update the window shape regardless of the frozen
status of the window actor.
However, plain Xorg does not need this, as resized windows do not clear
to black, so add a new vfunc to window/x11 to indicate whether or not
the backing windowing system (either plain X11 or Xwayland) would
require the shape to be always updated.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/942
Currently, the window actor freeze/thaw implementation sets the frozen
state of the surface actor using `meta_surface_actor_set_frozen()`.
If we want to expand that behavior to also freeze/thaw commits for X11
windows running on Xwayland, we need to have a specific vfunc to abstract
that in the window actor specific implementation.

To make sure the frame is painted before the commits are thawed, freeze
the commits when invalidating the GDK window, only to thaw to it after
the actual frame draw is performed or the frame is destroyed.

Make sure we freeze commits before resizing the window as this will
clear the frame to black.
Set the "thaw on paint" flag so that the post paint for window actor X11
can then thaw the freeze initiated prior to the resize and keep the
freeze/thaw balanced.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/942
To be able to thaw commits following a resize that might have frozen
commits, to keep freezes and thaws even, we need a way to tell whether
a repaint should also thaw commits.
Add a flag to `MetaWindowX11` and the appropriate functions to set and
query it.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/942
Xwayland may post damages for an X11 window as soon as the frame
callback is triggered, while the X11 window manager/compositor has not
yet finished updating the windows.
If Xwayland becomes compliant enough to not permit updates after the
buffer has been committed (see [1]), then the partial redraw of the X11
window at the time it was posted will show on screen.
To avoid that issue, the X11 window manager can use the X11 property
`_XWAYLAND_ALLOW_COMMITS` to control when Xwayland should be allowed to
post the pending damages.
Add `freeze_commits()` and `thaw_commits()` methods to `MetaWindowX11`
which are a no-op on plain X11, but sets `_XWAYLAND_ALLOW_COMMITS` on
the toplevel X11 windows running on Xwayland.

At the moment we only disarm the watchdog timer set up for SYNC counter
requests if we're in the middle of a resize operation.
It's possible that the resize operation finished prematurely by the user
letting go of the mouse before the client responded. If that happens, when the
client finally updates mutter will erroneously still have the watchdog timer
engaged from before until it times out, leading to resizes for the next second
or so to not get processed, and the client to get blacklisted from future sync
requests.

This avoids using bogus geometric values from an unmapped actor to
determine whether an actor is on a logical monitor or not. This would

Without 'wayland/surface-actor: Reset and sync subsurface state when
resetting' this test would fail.
This also adds a simple framework for testing lower level Wayland
semantics.
In contrast to the test-client and test-driver framework, which uses
gtk and tests mostly window management related things, this framework is
aimed to run Wayland clients made to test a particular protocol flow,
thus will likely consist of manual lower level Wayland mechanics.
A private protocol is added in order to help out clients do things they
cannot do by themself. The protocol currently only consists of a request
meant to be used for getting a callback when the actor of a given
surface is eventually destroyed. This is different from the wl_surface
being destroyed due to window destroy animations taking an arbitrary
amount of time. It'll be used by the first test added in the next
commit.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/961
As with most other state that ends up being pushed to the actor and the
associated shaped texture, also push the texture and the corresponding
metadata from the actor surface. This fixes an issue when a toplevel
surface was reset, where before the subsurface content was not properly
re-initialized, as content state synchronization only happened on
commit, not when asked to synchronize.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/961
A actor surface may be reset by an xdg_toplevel if a NULL buffer is
attached. This should reset the actor state of the toplevel to an empty
state, while unmapping the previous actor. Subsurfaces, however, should
stay intact, including their relationship to the toplevel. They should
also not be yanked away from the actor of the actor surface prior to it
resetting, so that a window-destroy animation can include the subsurface
actor.
This fixes a potential crash when a subsurface tries to commit to its
wl_surface after the destroy animation of the toplevel has finished, as
the actor would at that point have been destroyed and cleared from the
actor surface struct, causing a segmentation fault.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/961
Similar to wl_list_foreach(), add
META_WAYLAND_SURFACE_FOREACH_SUBSURFACE() that iterates over all the
subsurfaces of a surface, without the caller needing to care about
implementation details, such as leaf nodes vs non-leaf nodes.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/961
While it's not very relevant now, as we would rarely create it anyway
since the buffer nor texture never changes for a surface, it will be in
the future, as the actor state (including its content,
MetaShapedTexture) will be synchronized by the MetaWaylandActorSurface
at a later point in time, and not by MetaWaylandSurface, at state
application time.

The method `relative_motion_across_outputs` is used to adjust the
distance/delta of a mouse movement across multiple monitors to take the
different scale factors of those monitors into account. This works by
getting the adjacent monitors that the movement-line/vector intersects
with and adjusting the final position (or end point of the
movement-line) by multiplying the parts of the line spanning across
different monitors with the scale factors of those monitors.
In the end of this calculation, we always want to set the new end
coordinates of the relative motion to the new end coordinates of the
adjusted movement-line. We currently only do that if all adjacent
monitors the line is crossing actually exist, because only then we end
up inside the "We reached the dest logical monitor" else-block and set
`x` and `y` to the correct values. Fix that and make sure the returned
values are also correct in case an adjacent monitor doesn't exist by
adding separate `target_x` and `target_y` variables which we update during
each pass of the while loop so we're always prepared for the while loop
exiting before the destination monitor was found.
Thanks to Axel Kittenberger for reporting the initial bug and tracking
the issue down to `relative_motion_across_outputs`.

Some ClutterOffscreenEffect subclasses, such as ClutterBrightnessContrastEffect,
early-return FALSE in pre-paint before chaining up. It's an important optimization
that avoids creating or updating the offscreen framebuffer.
However, if an offscreen framebuffer already exists by the time pre-paint fails,
it will be used *without* repaint the actor over it. That causes an old picture
of the actor to be displayed.
Fix that by always clearing the offscreen framebuffer when pre-paint fails.

When changing the 'enabled' property and disabling the offscreen effect,
it doesn't make sense to preserve the offscreen framebuffer. It's not
drawing, after all.
Furthermore, because ClutterOffscreenEffect only checks if the offscreen
framebuffer exists to decide whether or not to redraw, keeping the fbo
alive is a waste of resources.
Clear the offscreen framebuffer when the effect is disabled or enabled.

From `meta_cullable_cull_out`:
```
Actors that may have fully opaque parts should also subtract out a region
