Currently, we use cairo_region_t despite it being a thing wrapper around pixman_region_32
In order to push for a cairo-less and wayland only build in the future, replace
cairo_region_t with a thin wrapper that is almost a copy of the upstream cairo implementation

The test and dist CI jobs run wrap the meson calls in dbus-runner to
avoid setting up dbus servers and mocking services for every test but
the dbus-runner invocation from meson test didn't actually skip all the
setup.
This nested mocking also doesn't work because the system bus is assumed
to be the host system bus and not a mocked one.

Make CoglBuffer an abstract class and inherit the various Cogl*Buffer types from it.
As none of the subclasses is overriding the vtable functions, they were not turned into
vfuncs but plain function pointers in CoglBuffer.

- Make Texture a parent GObject class and move the vtable funcs as vfuncs
instead of an interface as we would like to have dispose free the TextureLoader.
- Make the various texture sub-types inherit from it.
- Make all the sub-types constructors return a CoglTexture instead of their respective
specific type. As most of the times, the used functions accept a CoglTexture,
like all the GTK widgets constructors returning GtkWidget.
- Fix up the basics of gi-docgen for all these types.
- Remove CoglPrimitiveTexture as it is useless: It is just a texture underhood.
- Remove CoglMetaTexture: for the exact same reason as above.
- Switch various memory management functions to use g_ variant instead of the cogl_ one
Note we would still want to get rid of the _cogl_texture_init which is something

There are existing extensions that implement desktop icons as
a combination of a GTK program and a small extension to make
the wayland window behave as if it was of type DESKTOP on X11.
That's quite painful, as it requires reimplementing WM behavior
that is already implemented in mutter itself (stacking, stickiness,
skip-taskbar, ...), as well as modifying gnome-shell to consider
the window in addition to "real" DESKTOP windows (workspace-switch
animations, ctrl-alt-tab, ...).
In addition to that, other extensions may also have special handling
of DESKTOP windows, and their code cannot easily be monkey-patched
to handle "alternative" desktop icons.
This whole game of whack-a-mole can easily be avoided by allowing
desktop-icons extensions to mark their desktop windows as DESKTOP,
so do just that.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3305>

When running headless, only the invalid modifiers are advertised.
That breaks with the NVIDIA proprietary driver which then rejects the
buffers created with the invalid modifier, and that kills Xwayland,
meaning that running Xwayland on top of a mutter based compositor
headless is not possible.
The reason the modifiers are not sent is because AddFb2 is not supported
when running headless.
Other compositors (weston, wlroots) would still send the modifiers even
without AddFb2, and Xwayland works fine on those compositors when
running headless.
Remove the requirement for AddFb2 to send the modifiers, so that
Xwayland can work fine on top of mutter headless with the NVIDIA
proprietary driver.

`clutter_actor_destroy()` queues a stage update. Under certain

with the stage update triggered by the following
`clutter_virtual_input_device_notify_button()`, occasionally resulting in
`wait_stage_updated()` to return before the

This notably became more common since

Certain kernel drivers can take an unreasonably long time to

At the moment if a thread is made real-time there's no going back,
it stays real-time for the duration of its life.
That's suboptimal because real-time threads are expected by RTKit to
have an rlimit on their CPU time and certain GPU drivers in the kernel
can exceed that CPU time during certain operations like DPMS off.
This commit adds two new ref counted functions:
meta_thread_{un,}inhibit_realtime_in_impl
that allow turning a thread real-time or normally scheduled. At the same
time, this commit stores the RTKit proxy as private data on the thread
so that it can be reused by the above apis.

If we queued a mode set, but didn't end up compositing all frames, we'll
have pending mode sets in a hash table waiting to be applied. If we
before all monitors again try to reconfigure things we should drop the

We already do this when we're doing so when generating views, but when
just unsetting modes, we didn't, so fix that.

We had a function called "reset_modes()" on MetaRendererNative, but what
it expected to do was to unset all modes on all CRTCs. Despite this, it
had code to unset modes on unconfigured CRTCs, probably because it was

Make this a bit easier to follow by renaming the function
"unset_modes()" and fold the function doing the unsetting into the
function itself.

Intel has started to advertise big gamma LUT sizes on some hardware
because the hardware supports segmented LUTs. This means they have a lot
more precision at certain segments then others. The uAPI can't expose
this functionality meaningfully so they chose to expose a huge number of
TAPs to sample from to their segmented LUT.
This increase in uAPI LUT size resulted in stack overflows because we
allocated the LUT on the stack. This commit moves it to the heap
instead.

1. Centralize stride calculation in one function.
2. For dmabufs query the stride instead of assuming a certain value.
3. For system memory buffers use the pixel format to calculate the
stride.
4. Stop negotiating `SPA_PARAM_BUFFERS_size` and
`SPA_PARAM_BUFFERS_stride`.
2. fixes an actual bug where we reported wrong max buffer sizes,
resulting in crashes in Gstreamer when doing area screencasts on AMD
GPUs.
The reasoning for 4. is that the values were possibly wrong for
dmabufs as the negotiation happens before we create any buffers.
Further more neither Mutter nor the common consumers required it.
The later either ignore the values (OBS), always accept (gstpipewiresrc)
them or calculate the exact same possibly wrong values (libwebrtc).

With EI support wired to XTEST, and oeffis being enabled in Xwayland
means that XTEST will always go through the XDG portal.
While this the intended behavior for the general use case of Xwayland
running rootless on a desktop compositor, that breaks when Xwayland is
running on a nested compositor, because the portal is for the entire
session and not limited to the nested Wayland compositor.
Enable XDG portal support in Xwayland only when we managed to connect
to the GNOME session manager, which means we are running in a full
desktop session, and not in any form of nested mode.
This is determined by simply using the status returned by set_gnome_env()
which will fail if not connected to a GNOME Session manager.

There's two aspects from its documentation
(https://xkbcommon.org/doc/current/group__state.html#gae56031a8c1d48e7802da32f5f39f5738)
affecting us here:
1. "This function is similar to xkb_state_key_get_syms(), but intended for
users which cannot or do not want to handle the case where multiple
keysyms are returned (in which case this function is preferred)."
We are indeed in that field, and have been for a long time.
2. "This function performs Capitalization Keysym Transformations."
This is unlike the xkb_key_get_syms() function that we use, and
convenient here for parity with X11 since it behaves exactly that
way.
Fixes cases where the keysym for some keys is not properly capitalized
when caps lock is toggled, due to the output of capslock+key being
different from shift+key. An example of this is 'é' in french(azerty)
layout (bound to the '2' key). Even though shift+2 outputs '2',
capslock+é should output 'É'.

This is similar, but reserved for the crossing events induced by the

Focus follows mouse is meant to avoid focusing windows that happened
to pop up under the pointer, e.g. due to mapping, workspace changes,
etc... On X11, this has been done since ancient times through a
moderately complex synchronization mechanism, so mutter would know
to ignore crossing events caused on those situations.
This mechanism is much prior to XInput 2 though, where we may know
this in a more straightforward way: If the sourceid of the crossing
event is a logical pointer (i.e. equals deviceid), the crossing event
was triggered logically, and not through user input.
Perform this simpler check, and drop the existing mechanism to
ignore logically induced crossing events.

The virtual stream source with CURSOR_MODE_EMBEDDED uses
META_STAGE_WATCH_AFTER_PAINT as the callback for recording its frame. In
this stage of the paint though, there is no ClutterPaintContext anymore
(there only is a paint context during the paint, not afterwards).
The callback (actors_painted()) tries to get the redraw clip from the paint
context, and we end up with a NULL pointer crash.
We actually do still have a redraw clip at this point, so because everyone
uses the paint context to get the redraw clip anyway, just pass the redraw
clip to the stage watches directly.

After an event has been handled such that it bypasses both Clutter and
Wayland, e.g. when handling a keybinding, bypass_clutter would get
unset in the presence of a wayland grab. This means that the event is
handled both as a keybinding and by Clutter.
In the case of switcher popups in gnome-shell in the presence of a gtk4
autohide popover this meant that instead of selecting the next element,
it would select the one after that. If there are only two elements, as
is common with input sources, this would mean going back to the current
one, preventing switching them with a single press of the keybinding.

When a device is added, libei does not allow adding additional regions
for that particular device, as it is already advertised to the EI
client.
As a result, mutter currently effectively only adds the first region to
a device, but not the others.
This makes input in multi monitor sessions only possible on one monitor,
as the EI client cannot look up the other regions, since they were not
advertised to it.
Fix this situation by not adding and resuming the device, when a shared
device is used.
Instead, for shared devices, always add all regions first, and then
after that, add and resume the device.

Avoid passing the MetaSeatImpl, since it may be potentially null at

These objects already have a pointer to the ClutterSeat that has a
pointer to the MetaSeatImpl in its native implementation. This data

It's the 10 bit equivalent to NV12 and uses the same layout as P016, i.e.
16 bit components with the lowest 6 bits set to 0 (padding), allowing us
to use 16 bit "subformats".
Thus adding support is quite trivial as we can reuse the NV12 shader.
The format is widely supported in decoding and display hardware (on Intel
since Kaby Lake), as well as modern codecs (AV1, VP9, HEVC) and has
visible quality advantages over NV12.
Note that the additional colors are lost if composited to a 8 bit RGB
framebuffer. Switching between direct scanout and compositing can thus
cause quality differences. This is no new phenomena, however, as the
same is the case already for e.g. GL clients using 10 bit formats -
including video players.
Also note that P012 and P016 could trivially added as well - it's not
done here as they are uncommen and thus hard to test.

These shaders can be used for similar formats with other component
sizes since the values are represented as floats. So whether the source

Realizing a cursor will assume view related state objects are valid so
they can mark them as dirty. This assumption broke when there were a
scale changed that happened with multiple CRTCs, as we'd create view
object by view object as we realized the texture. Realizing the texture
would trigger a signal that had the handler assuming the validity of all
view objects, but if we only had gotten to the first, the second view
would not be there yet, thus we'd be doing a NULL pointer dereference.
Creating the view objects first, then handling the updating avoids this
problem by making the already done assumption valid on hotplugs.
The test case added tests exactly this series of events, and uses a
virtual monitor as a cheap trick to make the KMS CRTC based view the
first one, and an arbitrary view the second that previously had its view
object initialized too late.
