When a configuration has a fractional scale, but we're using a physical
monitor layout, we can't use the scale, but if we do, we end up with
wierd issues down the line. Just discard the config if we run into this.
Eventually we probably want to store the layout mode in the
configuration so we can handle more seamless switching between physical
and logical layout mode, but first do this.

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.

These objects already have a pointer to the ClutterSeat that has a

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
value was stored in 8bit, 10bit or 16bit doesn't matter - the driver

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.

Commit 3bfcb6d1 fixed the check for tiling via keybindings, but
ignored a subtle edge case when tiling with the pointer: The
monitor used for tiling is the monitor with the pointer, which
is not necessarily the one that contains the largest part of the
window.
That is, the correct monitor to check against depends on the
context where the function is called. We can either figure
it out automatically via the current window drag, or make it
a parameter.
The latter is clearer, because the callers already decide which
monitor to use for tiling anyway.

These snippets are retrieved anew every time a window is resized. But
callers never modify them, they're effectively read-only so cache them

This is required to convince the pipeline hash that each reuse of the

`CoglPipelineSnippetList` only does shallow comparisons and there's no

GInitable initialization is failable, currently, it may fail before error
traps are initialized, but error traps would be invariably deinitialized on
finalize() of the failed object. This results in an assert hit, on top of the
original failure to initialize the backend.
The libX11 error handlers are a pure client-side construct, and not a server
request, they just need XInitThreads() called to set up the library-side locks

Use work area from the monitor that the window is currently on to

Window tiling is disabled for monitors with portrait orientation, but
the work area we use to detect portrait orientation is taken from the

This works fine for edge tiling using the mouse, but this is broken when
using keybindings for window tiling because your mouse pointer could be
on a different monitor that has horizontal orientation.

The _NET_WM protocol, written before the birth of XInput 2.x, does have
no notion of different input devices whatsoever. Anyways, in a X11 session
it is safe to assume this refers about the Virtual Core Pointer since
every input device by default drives it (incl. touchscreens through the
"pointer emulating sequence", and styli).
This assumption falls apart in a Wayland session with non-pointer input,
since we do actually distinguish between all the distinct pointer devices
and touchpoints, and do not let them emulate mouse input.
We do need to specify a device/sequence there to drive the window
move/resize operation. The _NET_WM_MOVERESIZE message just gives us the
x/y root coordinates the resize was started from, so work from there
into guessing what is the most likely device/sequence that did trigger
the request on the client side.
Conversely, on Wayland we do not need to check for possible race
conditions in the pressed button states since we have larger guarantees
about not missing these events if we checked for the button modifier
mask beforehand, so make that race condition check specific to the
X11 sessions.

When we call get_grab_info() to get the sequence, device and coordinates for

MetaWaylandPointer, assuming that it's set to the core pointer.
In the case where there is no pointer device present on the seat (so no
mouse nor touchpad), the wayland pointer remains disabled though, and
pointer->device is NULL.
This means touch window dragging on hardware without pointer devices
present is broken (because MetaWindowDrag assumes that there's a valid
device passed in meta_window_drag_begin()). Fix it by taking the core
pointer directly from ClutterSeat instead of going the extra detour through
MetaWaylandPointer.

Sometimes it makes no sense to have a shared pointer device, for example
when they have no set region occupying the global stage coordinate
space. This applies to for example window screen cast based pointer
device regions - they are always local to the window, and have no
position.
We do need shared absolute devices in some cases though, primarily
multi-head remote desktop, where it must be possible to keep a button
reliably pressed when crossing monitors that have their own
corresponding regions.
To handle this, outsource all this policy to the one who drives the
emulated input devices. Remote desktop sessions where the screen casts
correspond to specific monitors (physical or virtual), we need to make
sure they map to the stage coordinate space, while for window screencast
or area screencasts, we create standalone absolute pointer devices with
a single region each.

Under strange timings, the GTK frames client may implicitly queue
relayouts that end up disagreeing with the latest frame size as
given by Mutter, this results in GTK calling XResizeWindow, and
Mutter plain out ignoring the resulting XConfigureRequestEvent
received.
This however makes GTK think there's pending resize operations,
so at the next resize it will freeze the window, until enough
resizes happened to thaw it again. This is seen as temporary
loss of frame-sync ness (e.g. frozen frame, and other weird
behavior).
In order to make GTK happy and balanced, reply to this
XConfigureRequest, even if just to ignore it in a more polite
way (we simply re-apply the size Mutter thinks the frame should
have, not GTK), this results in the right amount of
ConfigureNotify received on the frames client side, and the
surface to be thawed more timely, while enforcing the size as
managed by Mutter.

This changes how state is tracked by introducing an explicit state. We
need this since we use asynchronous calls to the out of process
component that handles actual inhibitation, including idleness.
This means if inhibitations changes rapidly, we might end up with an
incorrect state if we e.g. try to uninhibit while we're currently trying
to inhibit.
This is done by adding a state variable that accounts for the pending
state, as well as the active state, with a function that looks at the
current conditions to derive what state we should be in, and what state
we are in, to decide what the next action should be.
For example, if we're trying to inhibit, but now wants to uninhibit,
we'll wait for the inhibit call to complete, recheck what we want, which

This fixes the following
1. Minimize window; minimize animation starts
2. Do something that immediately destroys the animated actor (e.g. terminate)
3. This triggered the timeline of the animation to emit a "stopped"
signal while all transitions of the actor were destroyed
Previously we'd implicitly animate the scale again (set_scale(..)) which
created a new transition The hash table iterator didn't like this and
abort():ed

The 'suspend state' is meant to track whether a window is likely to be
visible any time soon. The hueristics for this are as follows:
* If a window is hidden, it will enter the 'hidden' state.
* If a window is visible, and unobscured, it will enter the 'active'
state.
* If a window is visible, but obscured by another window, it will enter
the 'hidden' state.
* If there is a mapped clone of a window, it will enter the 'active'
state.
* If the window has been in the 'hidden' state for 3 seconds, it will
enter the 'suspended' state.
This will eventually be communicated to Wayland clients so that they can
change their behaviour to e.g. save power.

Previously it transformed a physical CRTC coordinate to a logical desktop
coordinate. But current and future users of the function all require
conversion from logical coordinates to physical coordinates. We would have
had to always invert the transform parameter which is a waste of time when
we can instead just invert the function behaviour.
We also simplify the parameters to show both the point coordinate and the
area dimensions are potentially transformed.

When creating a new stream, check if the preferred format is
different from the default (COGL_PIXEL_FORMAT_BGRX_8888). If
it is, then also include it in the list of potential formats
for the stream.
COGL_PIXEL_FORMAT_BGRX_8888 is still passed around as it's
both the default, and the fallback for when things go wrong.
When creating buffers, use the negotiated SPA format instead
of a hardcoded value. We leave it to PipeWire to figure out
what's the best format, since clients may not support the
preferred format of the stream.
Due to how chaotic things got, this commit also cleans up
the create_pipewire_stream() to use an auxiliary array of
SPA formats, which is then iterated on in order to generate
the format pods.

In future commits, we will want to create DMA-BUFs with pixel
formats other than COGL_PIXEL_FORMAT_BGRX_8888. In preparation
for that, let's start passing a new pixel format parameter to
this function, and the corresponding winsys vfunc.
All callers of this function pass COGL_PIXEL_FORMAT_BGRX_8888
for now. Next commits will change that.

Freeing the window opaque region rather than the frame one when was
leaking the frame opaque region and wrongly setting the window opaque
region to NULL.

This is something the compositor could now track by itself, instead of
being pushed through events. It also makes more sense to do this directly
when the grabbing conditions change, as opposed to the next event.

Except for the tests that launches `mutter`, use a custom shell
implementation. It's roughly a copy of default.c with some cleanups on
top. A custom shell allows for a bit more freedom when doing testy
things.

This splits culling into two different phases to move unobscured region
culling to pre-paint to fix#2680. This is needed as direct scanout
skips the paint phase altogether, but the pre-paint phase always runs as
it's used for selecting the direct scanout surface.

With the ClutterEvent subtype structs sealed, this remains the only useful
struct type that is now usable on the Javascript side. Make all
ClutterActorClass event vmethods use ClutterEvent, and update all users
to this change.

In test situations we sometimes do not create a libinput context, so
our check on dispose to see if we need closing the input thread is off
if META_SEAT_NATIVE_FLAG_NO_LIBINPUT was provided.
Check the input thread existing instead, since that is the thing we
want to undo here.
