FLT_MIN is the smallest *positive* number above 0 that can be
represented as floating point number. If this is used to initialize the
maximum x/y coordinates of a rectangle, this will always be used if all
x/y coordinates of the rectangle are negative. This means that picking
at 0,0 will always be a hit for such rectangles.
Since mutter creates such a window for server side decorations on X11,
this window will always be picked at 0,0 preventing clicking/hovering
the activities button in gnome-shell at that coordinate.
Fixes https://gitlab.gnome.org/GNOME/mutter/issues/893
Using the same scale for the window as the
logical monitor only works correctly when having
the experimental 'scale-monitor-framebuffer'
feature enabled.
Without this experimental feature, the stream
will contain a black screen, where the actual
window only takes a small part of it.
Therefore, use a scale of 1 for the non-
experimental case.
Patch is based on commit 3fa6a92cc5.

At this point only the gl driver is at all aware of the difference
between core and compat contexts. COGL_PRIVATE_FEATURE_GL_FIXED is also
now quite misnamed, since we're using the GLSL pipeline even for pre-GL3
contexts. Remove the private feature and handle the few remaining
differences by checking the driver class inside the gl driver.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/973
There's quite a bit of CoglContext that properly belongs to the driver.
Add some hooks to allow the context to create/destroy such state. We
don't have driver-private storage in the CoglContext yet, though we
probably should.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/973
Podman can also be used to create the image. The only thing to keep in
mind with podman is to add --format docker, so that the image will be

'xwayland: Do not queue frame callbacks unconditionally' changed the
frame callback behavior of Xwayland surfaces so that they behave the
same way as other actor surfaces (e.g. xdg-shell ones), except for the
case when they are initially assigned.
Remove this special casing as well including the now incorrect comment,
so that the Xwayland surfaces behave the same as the others in this
regard also when assigning.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/964
The vfunc is not called when a surface commits its state, but when the
state is applied. Make this clearer by changing the name to
"apply_state" (and "pre_apply_state").
https://gitlab.gnome.org/GNOME/mutter/merge_requests/907
This changes how asynchronous window configuration works. Prior to this
commit, it worked by MetaWindowWayland remembering the last
configuration it sent, then when the Wayland client got back to it, it
tried to figure out whether it was a acknowledgment of the configuration
or not, and finish the move. This failed if the client had acknowledged
a configuration older than the last one sent, and it had hacks to
somewhat deal with wl_shell's lack of configuration serial numbers.
This commits scraps that and makes the MetaWindowWayland take ownership
of sent configurations, including generating serial numbers. The
wl_shell implementation is changed to emulate serial numbers (assuming
each commit acknowledges the last sent configure event). Each
configuration sent to the client is kept around until the client one. At
this point, the position used for that particular configuration is used
when applying the acknowledged state, meaning cases where we have
already sent a new configuration when the client acknowledges a previous
one, we'll still use the correct position for the window.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/907
In Wayland, window configuration is asynchronous. Window geometry is
constrained, the constrained geometry is sent to the client, and the
client will adapt its surface and acknowledge the configuration. When
acknowledged, we shouldn't reconstrain again, as that may invalidate the
constraint calculated for the configured size.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/907
Historically, wl_shell clients used to pretend the input region was
equivalent to the window geometry, so for "correctness" lets do that
here too. This makes wl_shell clients with drop shadow behave marginally
better than before.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/907
This moves the cached subsurface surface state into the generic
MetaWaylandSurface namespace. Eventually it'll be used by other surface
roles which as well aim to implement synhcronization.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/907
The name didn't communicate it was about surface state, and it somewhat
confusingly had the name "pending" in it, which could be confused with
the fact that while it's used to collect pending state, it's also used
to cache previously committed pending state.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/907
With the eventual aim of exposing the internals of MetaWaylandSurface
outside of meta-wayland-surface.c, make users of the pending state use a
helper to fetch it. While at it, rename the struct field to something
more descriptive.

The intention of meta_window_wayland_move_resize() is to finish a
move-resize requested previously, e.g. by a state change, or a
interactive resize. Make the function name carry this intention, by
renaming it to meta_window_wayland_finish_move_resize().
https://gitlab.gnome.org/GNOME/mutter/merge_requests/907
Presumably this function is supposed to be like
meta_kms_impl_simple_handle_page_flip_callback() but the condition in the
if-statement is inverted. Fix the inversion to make these two functions look
alike.
This is part 2 of 2 fixing a complete desktop freeze when drmModePageFlip()
fails with EINVAL and the fallback to drmModeSetCrtc() succeeds but the success
is not registered correctly as completed "flip". The freeze occurs under
wait_for_pending_flips() which calls down into meta_kms_impl_device_dispatch()
which ends up poll()'ing the DRM fd even though drmModeSetCrtc() will not
produce a DRM event, hence the poll() never returns. The freeze was observed
when hotplugging a DisplayLink dock for the first time on Ubuntu 19.10.
This patch makes meta_set_fallback_feedback_idle() actually end up calling into
notify_view_crtc_presented() which decrements
secondary_gpu_state->pending_flips so that wait_for_pending_flips() can finish.
CC stable: gnome-3-34
https://gitlab.gnome.org/GNOME/mutter/merge_requests/953
mode_set_fallback() schedules a call to mode_set_fallback_feedback_idle(), but
it is possible for Mutter to repaint before the idle callbacks are dispatched.
If that happens, mode_set_fallback_feedback_idle() does not get called before
Mutter enters wait_for_pending_flips(), leading to a deadlock.
Add the needed interfaces so that meta_kms_device_dispatch_sync() can flush all
the implementation idle callbacks before it checks if any "events" are
available. This prevents the deadlock by ensuring
mode_set_fallback_feedback_idle() does get called before potentially waiting
for actual DRM events.
Presumably this call would not be needed if the implementation was running in
its own thread, since it would eventually dispatch its idle callbacks before
going to sleep polling on the DRM fd. This call might even be unnecessary
overhead in that case, synchronizing with the implementation thread needlessly.
But the thread does not exist yet, so this is needed for now.

When rendering on-stage, it might be necessary to push offscreen
framebuffers to the paint context by external consumers, such as
GNOME Shell effects.
Expose clutter_paint_context_push|pop_framebuffer().
https://gitlab.gnome.org/GNOME/mutter/merge_requests/955
This means CoglContext is now also introspected, although its
constructor and some getters are skipped to avoid having to expose even
more types. This makes it possible to create pipelines using Javascript.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
They have been deprecated for a long time, and all their uses in clutter
and mutter has been removed. This also removes some no longer needed
legacy state tracking, as they were only ever excercised in certain
circumstances when there was sources (pipelines or materials) on the now
removed source stack.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
This means cogl_set_source_color*() that switches to the opaque or
blending pipeline, or cogl_source_set_texture() which switches to the
texture pipeline.
Left is the opaque pipeline, as it is still used to compare other
pipelines to check whether they are opaque or not, and as the default
pipeline still pushed to the source stack during initialization.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
Change the warp modes test to sanity check CoglPrimitive based polygon
drawing instead of cogl_polygon(). This removes some checks, as
cogl_polygon() has explicitly documented special behaviour for automatic
wrap modes, which CoglPrimitive does not.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
Stop using API that uses the implicit Cogl framebuffer stack, (e.g.
cogl_push_matrix()) and replace usage by the corresponding API taking an
explicit framebuffer (e.g. cogl_framebuffer_push_matrix()).
For offscreens etc, the offscreen framebuffer is still pushed to and
popped from the Cogl framebuffer stack, so that paint nodes still draw
to the right framebuffer.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
While we still push and pop to the Cogl framebuffer stack, as so is
still needed to render the actors correctly, don't use the API using the
implicit framebuffer stack ourself in the offscreen effect code.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
Instead of using cogl_polygon(), which uses deprecated API, implement
polygon drawing using the CoglPrimitive API family. While the test might
have been used to explicitly test cogl_polygon() it could still be
useful to test the non-deprecated way of rendering polygons.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
Port tests to use API such as cogl_framebuffer_push_matrix() instead of
cogl_push_matrix() all over the Clutter tests, with one exception:
cogl_polygon(). It'll be ported over in a separate commit, as it is less
straight forward.
Implicitly set CoglMaterial properties are changed to explicitly created
and destructed CoglPipelines with the equivalent properties set.
cogl_push|pop_framebuffer() is replaced by explicitly passing the right
framebuffer, but tests still rely on cogl_get_draw_framebuffer() to get
the target framebuffer.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
clutter_paint_node_get_framebuffer() fell back on
cogl_get_draw_framebuffer() when the root node didn't have a custom
get_framebuffer vfunc. As this relies on deprecated implicit Cogl stack
API, it needs to go away, so handle this in the caller that knows more
about the context.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
Instead of using the intermediate stage state "active framebuffer" to
find the framebuffer a paint eventually targets, use the "base
framebuffer" of the paint context, as this more correctly corresponds to
the end point of a paint. It also means we can then later remove this
intermediate state from the stage.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
Instead of pushing and popping the Cogl framebuffer stack, use the
framebuffer passed around using the pick context. This removes usage of
the deprecated framebuffer stack when picking.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
Rendering off stage we never cull, and previously this was checked by
comparing the "active framebuffer" of the stage, to the current
framebuffer in the cogl stack. Replace this by checking whether the
current paint context is currently drawing on stage or not.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
Just as with painting, add a pick context that carries pick related
temporary state when doing actor picking. It is currently unused, and
will at least at first still carry around a framebuffer to deal track
view transforms etc.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
When painting, actors rely on semi global state tracked by the state to
get various things needed for painting, such as the current draw
framebuffer. Having state hidden in such ways can be very deceiving as
it's hard to follow changes spread out, and adding more and more state
that should be tracked during a paint gets annoying as they will not
change in isolation but one by one in their own places. To do this
better, introduce a paint context that is passed along in paint calls
that contains the necessary state needed during painting.
The paint context implements a framebuffer stack just as Cogl works,
which is currently needed for offscreen rendering used by clutter.
The same context is passed around for paint nodes, contents and effects
as well.
In this commit, the context is only introduced, but not used. It aims to
replace the Cogl framebuffer stack, and will allow actors to know what
view it is currently painted on.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
It's not always clear how the dma-buf functions work (e.g. where memory
is allocated) without actually going in-depth in the code. This just

Checking the leds is not really accurate, since some devices have mode
switch buttons without leds. Check in the button flags whether they are
mode switch buttons for any of ring/ring2/strip/strip2, and return the
appropriate group.

While most of the code to compute a window's layer isn't explicitly
windowing backend specific, it is in practice: On wayland there are
no DESKTOP windows(*), docks(*) or groups.
Reflect that by introducing a calculate_layer() vfunc that computes
(and sets) a window's layer.
(*) they shall burn in hell, amen!
https://gitlab.gnome.org/GNOME/mutter/merge_requests/949
Most of the layer computation that the stack does actually depends
on the windowing backend, so we will move it to a vfunc.
However before we do that, split out the bit that will be shared.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/949
When a window that should be stacked above another one is placed in a lower
layer than the other window, we currently allow promoting it to the higher
layer when it has a "transient type". We should do the same when the window
is an actual transient of the other window.
This is particularly relevant for wayland windows, where types play a
much smaller role: Transient windows like non-modal dialogs (and since
commit 666bef7a, popup windows as well) currently end up underneath their
always-on-top parent.
https://gitlab.gnome.org/GNOME/mutter/issues/587
This was wrongly introduced in 75cffd0ec4. As the comment above explains, we
only want to queue redraws in response to surface/buffer damage.
This triggered a full redraw when using DMA buffers on Wayland as we currently
create a new texture on every buffer_attach(), breaking partial invalidation.
Fixes https://gitlab.gnome.org/GNOME/mutter/issues/947
There might be some inconsistent event for which we don't have a known
source device.
In the current state we don't handle them and we could crash when getting
the current device tool.
So, add an utility function that retrieves the source device for an event
that warns if no device is found, and use this for Motion, Key and Button
events.
In case we don't have a valid source in such case, just return early instead
of trying to generate invalid clutter events.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/823
Add an assert that we don't have a MetaWindow::monitor pointer that
points to an old MetaLogicalMonitor. After this, and the other
monitors-changed callbacks have been called, the old MetaLogicalMonitor
will be destoryed, thus if we didn't update the pointer here, we'll
point to freed memory, and will eventually crash later on.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/929
We do check the clip area as an optimization to know which input devices
might need updating state after a relayout (Assuming that if a device is
under a non-painted area, it's actor beneath didn't change).
Use the clip region for this, and drop the last usage of the clip region
bounds.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/867
This commit was split out from `cleanup: Use g_clear_signal_handler()
where possible` as it fixes an actual signal leak and should therefore
get backported to stable releases.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/940
This is inspired by 98892391d7 where the usage of
`g_signal_handler_disconnect()` without resetting the corresponding
handler id later resulted in a bug. Using `g_clear_signal_handler()`
makes sure we avoid similar bugs and is almost always the better
alternative. We use it for new code, let's clean up the old code to
also use it.
A further benefit is that it can get called even if the passed id is
0, allowing us to remove a lot of now unnessecary checks, and the fact
that `g_clear_signal_handler()` checks for the right type size, forcing us
to clean up all places where we used `guint` instead of `gulong`.
No functional changes intended here and all changes should be trivial,
thus bundled in one big commit.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/940
On wl_data_source destruction we used to indirectly unset the DnD selection
owner via the wl_resource destructor triggering the destruction of the
MetaWaylandDataSource, which would be caught through the weak ref set by
the MetaWaylandDragGrab.
This works as long as the grab is held, however we have a window between
the button being released and the drop site replying with
wl_data_offer.finish that the MetaWaylandDataSource is alive, but its
destruction wouldn't result in the call chain above to unsetting the DnD
source.
In other selection sources, we let the MetaWaylandDataDevice hold the
"ownership" of the MetaWaylandDataSource, and its weak ref functions unset
the respective MetaSelection owners. Do the same here, so the
MetaWaylandDataSource destruction is listened for all its lifetime.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/591
This is wrong for both clipboard and DnD, as the selection source
will still be able to focus another surface, and churn another
wl_offer.
We should just detach the data offer from the data source in this
case, and let the source live on. However, we should still check
that there is a source and an offer to finish DnD, do that when
handling the drop operation instead.
https://gitlab.gnome.org/GNOME/mutter/issues/591
Those were used to signal clipboard ownership around, but that got
replaced by MetaSelection and friends. These signals are no longer
listened on, so can be safely removed.
https://gitlab.gnome.org/GNOME/mutter/issues/591
The function create_texture() in test-wrap-modes.c takes a
TestUtilsTextureFlags. However a CoglTextureFlags is passed instead
in two calls. As the enums are identical this patch changes it to
use the TestUtils type.
The enum definitions:
typedef enum
{
COGL_TEXTURE_NONE = 0,
COGL_TEXTURE_NO_AUTO_MIPMAP = 1 << 0,
COGL_TEXTURE_NO_SLICING = 1 << 1,
COGL_TEXTURE_NO_ATLAS = 1 << 2
} CoglTextureFlags;
typedef enum
{
TEST_UTILS_TEXTURE_NONE = 0,
TEST_UTILS_TEXTURE_NO_AUTO_MIPMAP = 1 << 0,
TEST_UTILS_TEXTURE_NO_SLICING = 1 << 1,
TEST_UTILS_TEXTURE_NO_ATLAS = 1 << 2
} TestUtilsTextureFlags;
https://gitlab.gnome.org/GNOME/mutter/merge_requests/938
In _cogl_offscreen_gl_allocate we only want to perform certain actions if
COGL_OFFSCREEN_DISABLE_DEPTH_AND_STENCIL is not set in create_flags.
We perfrom this check with:
if (!offscreen->create_flags & COGL_OFFSCREEN_DISABLE_DEPTH_AND_STENCIL)
which is not correct as we negate the create_flags before the bitwise &.
It happens to work as intended though, as CoglOffscreenFlags only has one
element, and that element has the value 1. If the flag is not set then the
nagation of create_flags is true and the bitwise and with the element value
is true as well.
If any flag is set then the negation will give 0 and the bitwise & will be
false.
So while it works correctly it is fragile as either additional flags or a
change in the enum element value will break this check. This patch makes
things a bit more safe by adding parentheses to let the bitwise & happen
before the negation.
Definition of the enum:
typedef enum
{
COGL_OFFSCREEN_DISABLE_DEPTH_AND_STENCIL = 1
} CoglOffscreenFlags;

cogl_pipeline_get_front_face_winding() is supposed to return a CoglWinding. It
takes a CoglPipeline as argument and does the following input validation:
g_return_val_if_fail (cogl_is_pipeline (pipeline),
COGL_PIPELINE_CULL_FACE_MODE_NONE);
The returned COGL_PIPELINE_CULL_FACE_MODE_NONE is not a winding.
The function was added with this check 8 years ago in
5369b3c601
I do not see any of the two options in the CoglWinding as particularly good
choice for a return value on bad input, but let's go with
COGL_WINDING_CLOCKWISE as that is equivalent with the behavior for all
these years.

clutter_event_get_scroll_finish_flags() should return a ClutterScrollFinishFlags
but due to what looks like a bad copy/paste it instead returns a
ClutterScrollSource on asserts.
The definitions of the enums are these:
typedef enum
{
CLUTTER_SCROLL_SOURCE_UNKNOWN,
CLUTTER_SCROLL_SOURCE_WHEEL,
CLUTTER_SCROLL_SOURCE_FINGER,
CLUTTER_SCROLL_SOURCE_CONTINUOUS
} ClutterScrollSource;
typedef enum
{
CLUTTER_SCROLL_FINISHED_NONE = 0,
CLUTTER_SCROLL_FINISHED_HORIZONTAL = 1 << 0,
CLUTTER_SCROLL_FINISHED_VERTICAL = 1 << 1
} ClutterScrollFinishFlags;
The asserts would only return CLUTTER_SCROLL_SOURCE_UNKNOWN. This
is equal to CLUTTER_SCROLL_FINISHED_NONE which this patch uses
instead. Thus no functional change is intended. This only fixes a
compile warning.

It seems that sometimes these functions are called by Javascript in
GNOME Shell during tear down. This causes segfaults and crash reports,
but without any backtraces other than the entry and exit points into

We currently assume that the actor_animate() helper function returns
a timeline. However Clutter may skip implicit animations and simple
set properties directly, for example when the actor is hidden.
The returned timeline will be NULL in that case, and we abort when
using it as instance parameter to g_signal_connect().
Fix this by only setting up a completed handler when we are actually
animating, and complete the effect directly otherwise.

The actor is already in surface coordinate space, so we should not scale

Java applications might use override-redirect windows as parent windows for
top-level windows, although this is not following the standard [1].
In such case, the first non-override-redirect child window that is created
was marked as being on_all_workspaces since the call to
should_be_on_all_workspaces() returns TRUE for its parent, and this even
though the on_all_workspaces_requested bit is unset.
When a further child of this window was added, it was set as not having a
workspace and not being on_all_workspaces, since the call to
should_be_on_all_workspaces() for its parent would return FALSE (unless if
it is in a different monitor, and the multiple-monitors workspaces are
disabled).
Since per commit 09bab98b we don't recompute the workspace if the
on_all_workspaces bit is unset, we could end up in a case where a window can
be nor in all the workspaces or in a specific workspace.
So let's just ignore the transient_for bit for a window if that points to an
override-redirect, using the x11 root window instead.
Add a stacking test to verify this scenario (was failing before of this
commit).

Once we set the transient_for, we look for parent MetaWindow, so instead

Override-redirect windows have no workspace by default, and can't be parent

We're expected by MetaWaylandSurface to always pick the frame callbacks
out from the pending state when committing (applying) so that no frame
callbacks are unaccounted for. We failed to do this if our actor for
some reason (e.g. associated window was unmanaged) was destroyed. To
handle this situation better, store away the frame callbacks until we
some later point in time need to pass them on forward.

As noted in <cogl-texture-2d-gl.h> (now also removed), this is for
allowing external GL callers to promote one of their textures to a
CoglTexture. We aren't doing that and don't want to start.

For stable branches, we currently only check out the correct shell
branch for merge requests. For the regular pipeline, our code to
determine the current mutter branch fails because CI runs on a
temporary "pipeline/12345" branch that doesn't exist for gnome-shell.
Switching to the correct gitlab environment variable fixes that.

We ask XLib the next request serial number before performing other actions
triggered by meta_x11_display_set_input_focus_internal() that doesn't use
the request serial anyways. So, just request it before updating the focus
window as that's the operation that needs it.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/909
When using DesktopIcons extension and clicking in an icon, gnome-shell
starts an infinite loop caused by the first focus change that may trigger
on X11 a focus in/out event that leads to stage activation/deactivation
which never ends.
This happens because as part of meta_x11_display_set_input_focus_xwindow()
to focus the X11 stage window, we unset the display focus, but this also
causes to request the X11 display to unset the focus since we convolute by
calling meta_x11_display_set_input_focus() with no window, that leads to
focusing the no_focus_window and then a focus-in / focus-out dance that the
shell amplifies in order to give back the focus to the stage.
In order to fix this, mimic what meta_display_set_input_focus() does, but
without updating the X11 display, and so without implicitly calling
meta_x11_display_set_input_focus(), stopping the said convolution and
properly focusing the requested xwindow.
Also ensure that we're not doing this when using an older timestamp, since
this check isn't performed anymore.

This function is already checking for the focus surface client
matching the requestor. The type check was slightly bogus though
as it'd be an screwup in our code, make it an assert instead.
Also, move the check for the client having the focus into the
upper call, so this and wl_data_device.set_selection code can
get more in line.

`meta_surface_actor_is_obscured` implies that the actor got successfully culled
out and nothing of it will get painted. This includes that there are no clones,
no effects etc. In this cases we don't want to send frame callbacks, thus avoiding
unnecessary client work.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/918
When setting the root node as child of a clip or transform node, we add a
new reference to it, without removing the one that we've previously added
when getting it from the actor node (and that won't ever be unset by the
auto-pointer since the root_node is re-associated).
So, once we add the root node as child and re-define it, unref it.

Create the intermediate shadow framebuffer for use exclusively when a
shadowfb is required.
Keep the previous offscreen framebuffer is as an intermediate
framebuffer for transformations only.
This way, we can apply transformations between in-memory framebuffers
prior to blit the result to screen, and achieve acceptable performance
even with software rendering on discrete GPU.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/877
Previously, we would use a single offscreen framebuffer for both
transformations and when a shadow framebuffer should be used, but that
can be dreadfully slow when using software rendering with a discrete GPU
due to bandwidth limitations.
Keep the offscreen framebuffer for transformations only and add another
intermediate shadow framebuffer used as a copy of the onscreen
framebuffer.

A compositor is notably opaque (usually has nothing to be painted on!).
gnome-shell sets this hint, but there's no reason why we wouldn't want
it by default.
Also, the color buffer being cleared messes with stencil clips, as the
clear operation by definition ignores the stencil buffer. We want to
use these more extensively in the future, so just drop this API.

This is a workaround for X11 games which use randr to change the resolution
in combination with NET_WM_STATE_FULLSCREEN when going fullscreen.
Newer versions of Xwayland support the randr part of this by supporting randr
resolution change emulation in combination with using WPviewport to scale the
app's window (at the emulated resolution) to fill the entire monitor.
Apps using randr in combination with NET_WM_STATE_FULLSCREEN expect the
fullscreen window to have the size of the emulated randr resolution since
when running on regular Xorg the resolution will actually be changed and
after that going fullscreen through NET_WM_STATE_FULLSCREEN will size
the window to be equal to the new resolution.
We need to emulate this behavior for these games to work correctly.
Xwayland's emulated resolution is a per X11 client setting and Xwayland
will set a special _XWAYLAND_RANDR_EMU_MONITOR_RECTS property on the
toplevel windows of a client (and only those of that client), which has
changed the (emulated) resolution through a randr call.
This commit checks for that property and if it is set adjusts the fullscreen
monitor rect for this window to match the emulated resolution.
Here is a step-by-step of such an app going fullscreen:
1. App changes monitor resolution with randr.
2. Xwayland sets the _XWAYLAND_RANDR_EMU_MONITOR_RECTS property on all the
apps current and future windows. This property contains the origin of the
monitor for which the emulated resolution is set and the emulated
resolution.
3. App sets _NET_WM_FULLSCREEN.
4. We check the property and adjust the app's fullscreen size to match
the emulated resolution.
5. Xwayland sees a Window at monitor origin fully covering the emulated
monitor resolution. Xwayland sets a viewport making the emulated
resolution sized window cover the full actual monitor resolution.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/739
Add an adjust_fullscreen_monitor_rect virtual method to MetaWindowClass
and call this from setup_constraint_info() if the window is fullscreen.
This allows MetaWindowClass to adjust the monitor-rectangle used to size
the window when going fullscreen, which will be used in further commits
for a workaround related to fullscreen games under Xwayland.

This reverts commit 4918893326.
This commit prevented cogl_stage_cogl_redraw_view() from skipping
swap buffers entirely if the invalidation region ended up empty.
This meant we were actually swapping buffers when we didn't need to.
The source of the glitches was fixed more properly, so this just adds
extra work.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/898
Unknown since when, we started deferring the eglMakeCurrent for the
current framebuffer till we started painting on it, which means we
are preparing for rendering a view without guarantees that the
framebuffer we will paint to is the current drawing surface for the
EGL context.
A fairly common case where that assumption will break is multimonitor
set ups, in this case we will be preparing to paint to a view while
the current draw surface is that of the previously rendered view's.
Mesa will in this case return EGL_BAD_SURFACE when querying the buffer
age, since the surface is not yet the current draw surface. This
makes us give up on buffer age checks, and paint the whole view. Since
the problem repeats when painting the next view, we are effectively
doing full-screen redraws on all monitors.
Since cogl usually works implicitly, and querying the buffer age is
meaningless if you're not meant to paint on a surface, make the surface
the current draw surface implicitly before querying the buffer age.
This brings us glorious partial invalidations back when several views
had to be repainted.

In order to avoid log spamming, just warn once it starts to happen, not

Say you're using intel gen3, you poor soul. Your big-GL maxes out at 1.5
unless you use dirty tricks, but you do have GLES2. We try to fall back
to GLES in this case, but we only ever say eglBindAPI(EGL_OPENGL_API).
So when we go to do CreateContext, even though we think we've requested
GLES 2.0, the driver will compare that "2.0" against the maximum big-GL
version, and things will fail.
Fix this by binding EGL_OPENGL_ES_API before trying a GLES context.
https://gitlab.gnome.org/GNOME/mutter/issues/635
In find_onscreen_for_xid() we want to loop over the framebuffers
and skip any that is not onscreen.
The code today does this by negating the framebuffer type variable
and skipping if that equals COGL_FRAMEBUFFER_TYPE_ONSCREEN. This
actually works as the enum used will function as a boolean:
typedef enum _CoglFramebufferType {
COGL_FRAMEBUFFER_TYPE_ONSCREEN,
COGL_FRAMEBUFFER_TYPE_OFFSCREEN
} CoglFramebufferType;
But it is a bit weird logic and fragile if more types are added.
(not that I can think of any different type...)
To simplify this, and to silence a warning in clang this patch just
changes it to a != test.

This allows xdg_popup.grab() to work with styli. Without this check

Closes: https://gitlab.gnome.org/GNOME/mutter/issues/886
When a touch sequence was rejected, the emulated pointer events would be
replayed with old timestamps. This caused issues with grabs as they
would be ignored due to being too old. This was mitigated by making sure
device event timestamps never travelled back in time by tampering with
any event that had a timestamp seemingly in the past.
This failed when the most recent timestamp that had been received were
much older than the timestamp of the new event. This could for example
happen when a session was left not interacted with for 40+ days or so;
when interacted with again, as any new timestamp would according to
XSERVER_TIME_IS_BEFORE() still be in the past compared to the "most
recent" one. The effect is that we'd always use the `latest_evtime` for
all new device events without ever updating it.
The end result of this was that passive grabs would become active when
interacted with, but would then newer be released, as the timestamps to
XIAllowEvents() would out of date, resulting in the desktop effectively
freezing, as the Shell would have an active pointer grab.
To avoid the situation where we get stuck with an old `latest_evtime`
timestamp, limit the tampering with device event timestamp to 1) only
pointer events, and 2) only during the replay sequence. The second part
is implemented by sending an asynchronous message via the X server after
rejecting a touch sequence, only potentially tampering with the device
event timestamps until the reply. This should avoid the stuck timestamp
as in those situations, we'll always have a relatively up to date
`latest_evtime` meaning XSERVER_TIME_IS_BEFORE() will not get confused.

Make ClutterActor paint using ClutterTransformNode, ClutterClip
node, and ClutterActorNode. Essencially, the actor node is a
replacement for clutter_actor_continue_paint().
An interesting aspect of this commit is that the order of the
operations is reversed to be preserved.
Before being able to remove the dummy node hack, we'll need to
make ClutterEffects compatible with paint nodes first -- and
naturally, that's enough content for its own merge request.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/872
ClutterActorNode is a paint node that runs the 'paint'
function of an actor. It is a useful helper node to be
used during the transition to paint nodes.
The role of ClutterActorNode will change over time. For
now, it is just a call to clutter_actor_continue_paint(),
which also paints the effects. When ClutterEffect is
ported to paint nodes, ClutterActorNode will morph to
only notify the actor about the painting, and will become
a private node to Clutter.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/872
In a similar vein to commit 8fd55fef85. This notably failed when setting
the focus on the stage (eg. to redirect key events to Clutter actors).
Deeper in MetaDisplay focus updating machinery, it would check
meta_stage_is_focused() which would still return FALSE at the time it's
called.
This would not typically have side effects, but our "App does not respond"
dialogs see the focus change under their feet, so they try to bring
themselves to focus again. This results in a feedback loop.
Changing the order results in later checks on the X11 POV of the focus
being correct, so focus is not mistakenly stolen from the close dialog,
and it actually succeeds in keeping the key focus.

This is a _little_ strange, as we still fill in the vtable slot for
glRenderbufferStorageMultisampleIMG, and can in principle still call it.
But that feature was weird to begin with as we were only checking for

It might be the case that handling an event induces the stream to
trigger completion, hence removing itself from the list. In that
case we would operate on the no longer valid list element to fetch
the next one.
Keep a pointer to the next element beforehand, so we can tiptoe
over streams that did remove themselves.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/869
The streams were only detached from MetaX11Display (and its event handling)
on completion. This is too much to expect, and those might be in some
circumstances replaced while operating.
Make those streams detach themselves on dispose(), so we don't trip into
freed memory later on when trying to dispatch unrelated X11 selection events.

Instead of doing a roundtrip to the X server before setting it, rely on

Midscene tracking was used at a time that some Cogl users
could call random OpenGL API without going through Cogl.
That is not allowed anymore, and certainly not done by
Mutter and GNOME Shell.
Remove midscene tracking from CoglFramebuffer.

CoglJournal tracks a few OpenGL states so that they can
be batch-applied if necessary. It also has a nice property
of allowing purely CPU-based glReadPixels() when the scene
is composed of simple rectangles.
However, the current journal implementation leaves various
other GL states out, such as dithering and the viewport.
In Clutter, that causes the journal to be flushed when
picking, touching the GPU when we didn't really need to.
Track the viewport of the framebuffer in the journal so that
we can avoid flushing the journal so often.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/402
CoglFramebuffer checks the passed buffer bits in order to
detect when the fast path (that uses the journal) should
be used.
However, it also modifies one of the buffer bits that is
checked for the fast path, meaning we never actually hit
the fast path on cogl_framebuffer_cleaf4f().
Check the depth and color buffer bits before modifying them.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/402
Previously picking was done on an int (x,y) to address a particular pixel.
While `int` was the minimum precision required, it was also an unnecessary
type conversion.
The callers (input events mainly) all provide float coordinates and the
internal picking calculations also have always used floats. So it was
inconsistent and unnecessary to drop to integer precision in between those.
ABI break: This changes the parameter types for public function
`clutter_stage_get_actor_at_pos`, but its documentation is already
sufficiently vague to not need changing.

This is an extremely straightforward and minimalistic port of
CoglVector APIs to the corresponding Graphene APIs.

As the first step into removing Cogl types that are covered by
Graphene, remove CoglEuler and replace it by graphene_euler_t.
This is a mostly straightforward replacement, except that the
naming conventions changed a bit. Cogl uses "heading" for the
Y axis, "pitch" for the X axis, and "roll" for the Z axis, and
graphene uses the axis themselves. That means the 1st and 2nd
arguments need to be swapped.
Also adapt the matrix stack to store a graphene_euler_t in the
rotation node -- that simplifies the code a bit as well.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/458
Mutter requires Clutter, which requires Cogl. That means
Clutter requires all Cogl dependencies, and Mutter requires
all Clutter dependencies as well.
However, currently, Clutter does not pull in its dependencies,
which means we need to link against Cogl manually.
Add Clutter dependencies to declare_dependency() so that the
graphene dependency only needs to be declared once, for Cogl,
and pulled together.

As we will start adding support for more pixel formats, we will need to
define a notion of planes. This commit doesn't make any functional
change, but starts adding the idea of pixel formats and how they (at
this point only theoretically) can have multple planes.

plane pixel formats, this commit also adds assertions and if-checks to
make sure we don't accidentally try something that doesn't make sense.

When clutter actors with key focus are destroyed we emit ::key-focus-out on
them just after their destruction. This is against our assumption that no
signal should be emitted after "::destroy" (see GNOME/mutter!769 [1]), and
in fact could cause the shell to do actions that we won't ever stop on
destroy callback.
To avoid this to happen, use a private function to set its key-state (so we
can avoid looking for the stage) and emit ::key-focus-in/out events and use
this value in both clutter_actor_has_key_focus(),
clutter_actor_grab_key_focus() and on unmap and destruction to unset the
stage key focus before we emit the ::destroy signal.
As result of this, we can now avoid to unset the key focus on actor
destruction in the stage.

We were just looking at DnD actions which might still be unset at that
point. Instead of doing these heuristics, store the selection type on
the data offer.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/845
Requesting a selection with a NULL data source means "unset the clipboard",
but internally we use an unset clipboard as the indication that the
clipboard manager should take over.
Moreover, this unset request may go unheard if the current owner is someone
else than the MetaWaylandDataDevice.
Instead, set a dummy data source with no mimetypes nor data, this both
prevents the clipboard manager from taking over and ensures the selection
is replaced with it.
The MetaSelectionSourceMemory was also added some checks to allow for this
dummy mode.

Instead of taking resource and send/cancel funcs, take a

If we did a mode set, the gamma may have been changed by the kernel, and
if we didn't also update the gamma in the same transaction, we have no
way to predict the current gamma ramp state. In this case, read the
gamma state directly from KMS.
This should be relatively harmless regarding the race conditions the
state prediction was meant to solve, as the worst case is we get none or
out of date gamma ramps; and since this is for when gamma ramps are not
updated at mode setting time, we'd get intermediate gamma state to begin
with, so it's not worse than what we currently do anyway.

we'll be queued already, but with more correct damage. Without we simply
need to make sure we flush the callbacks if any area of surface is not
occluded.

For the most part, a MetaWindow is expected to live roughly as long as
the associated wl_surface, give or take asynchronous API discrepancies.
The exception to this rule is handling of reparenting when decorating or
undecorating a window, when a MetaWindow on X11 is made to survive the
unmap/map cycle. The fact that this didn't hold on Wayland caused
various issues, such as a feedback loop where the X11 window kept being
remapped. By making the MetaWindow lifetime for Xwayland windows being
the same as they are on plain X11, we remove the different semantics
here, which seem to lower the risk of hitting the race condition causing
the feedback loop mentioned above.
What this commit do is separate MetaWindow lifetime handling between
native Wayland windows and Xwayland windows. Wayland windows are handled
just as they were, i.e. unmanaged together as part of the wl_surface
destruction; while during the Xwayland wl_surface destruction, the
MetaWindow <-> MetaWaylandSurface association is simply broken.

ClutterActor took a reference in its transition 'stopped' handler,
aiming to keep the transition alive during signal emission even if it
was removed during. This is, however, already taken care of by
ClutterTimeline, by always taking a reference during its 'stopped'
signal emission, so no need to add another one.
This also has the bonus of making reference ownership simpler, as well
as avoidance of double free if an actor was destroyed before a
transition has finished.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/828
We get implicit, thus auto-removed, transitions, then manage them
manually by stopping them and emitting "completed" signals. This doesn't
work since they are removed and freed when stopped. To be able to emit
the "completed" signal, hold a reference while stopping, so that we
still can emit the signal as before.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/828
Implicit transitions had a referenced taken while emitting the
completion signals, but said reference would only be released if it was
had remove-on-complete set to TRUE.
Change this to instead remove the 'is_implicit' state and mark all
implicit transitions as remove-on-complete. This fixes a
ClutterPropertyTransition leak in gnome-shell triggered by e.g. showing
/ hiding menus.

Dropping the grab has the side effect that the pointer will be re-picked,
and it might find another surface with a pointer constraint. If that were
the case, the focus change would try to add the pointer constraint before
the now old focus surface released its own.
Just invert these operations, so the constraint is unset before the repick
that might enable another pointer constraint.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/779
Just like sync_focus_surface() does, we shouldn't set a focus surface while
the pointer is hidden, so the illusion that there is none remains.

We can't just update the state of the connector and CRTC from KMS since
it might contain too new updates, e.g. from a from a future hot plug. In
order to not add ad-hoc hot plug detection everywhere, predict the state
changes by looking inside the MetaKmsUpdate object, and let the hot-plug
state changes happen after the actual hot-plug event.
This fixes issues where connectors were discovered as disconnected while
doing a mode-set, meaning assumptions about the connectedness of
monitors elsewhere were broken until the hot plug event was processed.

Instead of storing the result of meta_prop_get_latin1_string() into
a temporary string value, g_strdup-ing that temp value storing the
g_strdup result into window->sm_client_id and then g_free-ing the
temporary string, we can pass window->sm_client_id as the place where
meta_prop_get_latin1_string() stores its result, since the result
from meta_prop_get_latin1_string() is itself a g_strdup-ed string,
so there is no need to g_strdup it again.
Note this drops the check to only issue the
"Window %s sets SM_CLIENT_ID on itself ..." warning once. This check is
not necessary as update_sm_hints() is only called once at window
creation time and is never called again.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/786
Use g_strdup instead of malloc + strcpy, this also gets rid of a bunch
of error checking which is no longer necessary, also adjust the free
path accordingly.
Note that there was a malloc + XFree mismatch in the removed error-handling.

latin1_string_from_results and utf8_string_from_results use g_strndup,
so the returned string should be freed with g_free, rather then with
free or XFree. This fixes all free-s of buffers returned by these 2
functions to properly use g_free.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/786
Use g_new0 instead of calloc for motif_hints_from_results and adjust
its callers to use g_free.

g_free pair.

The final version of the function was changed to allow points that are
touching the edge of a quadrilateral to be counted as "inside". Update

In `clutter_stage_view_blit_offscreen()`, the given clipping rectangle
is in “view” coordinates whereas we intend to copy the whole actual
framebuffer, meaning that we cannot use the clipping rectangle.
Use the actual framebuffer size, starting at (0, 0) instead.
That fixes the issue with partial repainting with shadow framebuffer
when fractional scaling is enabled.

Clutter actors might emit property changes in dispose, while unparenting.
However we assume that the ::destroy signal is the last one we emit for an
actor, and that starting from this moment the object is not valid anymore,
and so we don't expect any signal emission from it.
To avoid this, freeze the object notifications on an actor during its
disposition, just before the ::destroy signal emission.
Update the actor-destroy test to verify this behavior.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/769
Clutter actors unset their parent on dispose, after emitting the ::destroy
signal, however this could cause ::parent-set signal emission. Since we
assume that after the destruction has been completed the actor isn't valid
anymore, and that during the destroy phase we do all the signal / source
disconnections, this might create unwanted behaviors, as in the signal
callbacks we always assume that the actor isn't in disposed yet.
To avoid this, don't emit ::parent-set signal if the actor is being
destroyed.
Update the actor-destroy test to verify this behavior.

Mutter issues a synchronous grab on the pointer for unfocused client
windows to be able to catch the button events first and raise/focus
client windows accordingly.
When there is a synchronous grab in effect, all events are queued until
the grabbing client releases the event queue as it processes the events.
Mutter does release the events in its event handler function but does so
only if it is able to find the window matching the event. If the window
is a shell widget, that matching may fail and therefore Mutter will not
release the events, hence causing a freeze in pointer events delivery.
To avoid the issue, make sure we sync the pointer events in case we
can't find a matching window.

It was not the lack of forcing the shadow fb that caused slowness, but
rather due to the method the shadow fb content was copied onto the
scanout fb. With 'clutter: Use cogl_blit_framebuffer() for shadow FB'
we'll use a path that shouldn't be slow when copying onto the scanout
fb.
Also 437f6b3d59 accidentally enabled
shadow fb when using hw accelerated contexts, due to the cap being set
to 1 in majority of drivers. While the kernel documentation for the
related field says "hint to userspace to prefer shadow-fb rendering",
the name of the hint when exposed to userspace is
DRM_CAP_DUMB_PREFER_SHADOW, thus should only be taken into consideration
for dumb buffers, not rendering in general.
This reverts commit 437f6b3d59.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/818
The commit 'renderer/native: Use shadow fb on software GL if preferred'
attempted to force using a shadow fb when using llvmpipe in order to
speed up blending, but instead only did so when llvmpipe AND the drm
device explicityl asked for it.
Now instead always force it for llvmpipe and other software rendering
backends, and otherwise just query the drm device (i.e.
DRM_CAP_DUMB_PREFER_SHADOW).

If there is no transformation, use `cogl_blit_framebuffer()` as a

Since the recent clutter-content work, legacy scaling (in contrast
to the new stage-view-scaling) only applies to surfaces that belong
to a window. This broke scaling of DnD surfaces.
As a workaround, apply the same scaling on DnD-surface-actors until
we use stage-view-scaling by default and can remove this again.
Also: small corrections of geometry calculation
https://gitlab.gnome.org/GNOME/mutter/merge_requests/780
This allows us to implement more sophisticated logic for the different
cases. For DnD surfaces, use the geometry scale of the monitor where
the pointer is, instead of incorrectly assuming '1' as it was before.

The meta_display_update_focus_window() call has indirect dependencies
on the X11 focus window, in order to determine the correct focus window
on the Wayland side (i.e. may turn out NULL with certain X windows).
In order to have the right x11_display->focus_xwindow there, we should
perform first the focus update on the X11 display.
Fixes focusing of Java applications, as those don't seem to go through
_NET_ACTIVE_WINDOW.

With the addition of the locate-pointer special keybinding (defaults to
the [Control] key), we have now two separate special modifier keys which
can be triggered separately, one for the locate-pointer action and
another one for overlay.
When processing those special modifier keys, mutter must ensure that the
key was pressed alone, being a modifier, the key could otherwise be part
of another key combo.
As result, if both special modifiers keys are pressed simultaneously,
mutter will try to trigger the function for the second key being
pressed, and since those special modifier keys have no default handler
function set, that will crash mutter.
Check if the handler has a function associated and treat the keybinding
as not found if no handler function is set, as with the special modifier
keys.
https://gitlab.gnome.org/GNOME/mutter/issues/823
The `process_event()` would check for a existing keybinding handler and
abort if there is none, however the test is done after the handler had
been accessed, hence defeating the purpose of the check.
Move the check to verify there is an existing keybinding handler before
actually using it.

There were multiple bugs present after the ClutterContent transition.
Refactor `get_image` to:

- make the offscreen path take size arguments, so we can
easily change the assumption in get_image
- fix some clipping bugs on the way

Delayed clutter timelines might be removed while they are still in the
process of being executed, but if they are not playing yet their delay
timeout won't be stopped, causing them to be executed anyway, leading to a
potential crash.
In fact if something else keeps a reference on the timelines (i.e. gjs), the
dispose vfunc delay cancellation won't take effect, causing the timelines to
be started and added to the master clock.
To avoid this, expose clutter_timeline_cancel_delay() function and call it
if a timeline is not playing but has a delay set.
Fixes https://gitlab.gnome.org/GNOME/mutter/issues/815https://gitlab.gnome.org/GNOME/mutter/merge_requests/805
If a timeline is delayed and we request to stop or pause it, we are emitting
the "::paused" signal on it, however this has never been started, and so
nothing has really be paused.
So, just try to cancel the delay on pause and return if not playing.
No code in mutter or gnome-shell is affected by this, so it is safe to
change.

Some drivers expose EGL_EXT_image_dma_buf_import_modifiers so you can

Clutter stage used to compute the initial projection using a fixed z
translation which wasn't matching the one we computed in
calculate_z_translation().
This caused to have a wrong initial projection on startup which was then
correctly recomputed only at the first paint.
However, since this calculation doesn't depend on view, but only on viewport
size, perspective's fovy and z_near we can safely do this at startup and
only when any of those parameters change.
Then we can move the computation out _clutter_stage_maybe_setup_viewport()
since the cogl framebuffer viewport sizes aren't affecting this.

GCC's manpage says that this flag does the following:
Do not store floating-point variables in registers, and inhibit other
options that might change whether a floating-point value is taken from
a register or memory.
This option prevents undesirable excess precision on machines such as
the 68000 where the floating registers (of the 68881) keep more
precision than a "double" is supposed to have. Similarly for the x86
architecture. For most programs, the excess precision does only good,
but a few programs rely on the precise definition of IEEE floating
point.
We rely on this behaviour in our fork of clutter. When performing
floating point computations on x86, we are getting the wrong results
because of this architecture's use of the CPU's extended (x87, non-IEEE
confirming) precision by default. If we enable `-ffloat-store` here,
then we'll get the same results everywhere by storing into variables
instead of registers. This does not remove the need to be correct when
handling floats, but it does mean we don't need to be more correct than
the IEEE spec requires.

Instead of open coding the X11 focus management in display.c, expose
it as a single function with similar arguments to its MetaDisplay

MetaDisplay and MetaX11Display focus windows are slightly decoupled,

We have a "setup" phase, used internally to initialize early the x11
side of things like the stack tracker, and an "opened" phase where
other upper parts may hook up to. This latter phase is delayed during
initialization so the upper parts have a change to connect to on
plugin creation.

When starting standalone mutter and running using the native backend, we
always fall back on using the us pc105 keyboard layout. This can be very
frustrating if one is used to using some other keyboard layout, such as
dvorak, causing keyboard fumbling everytime when doing something with
standalone mutter.
Avoid this involuntary fumbling by having the default plugin query
localed what layout the user has actually configured the machine to
operate using. It doesn't add any keymap selection user interface, so
it'll always use the first one it encounters.

The commit f2f4af0d50 missed one situation
where mutter does things differently, i.e. changes what surface actor is
associated with a given window actor: reparenting a Xwayland window when
changing whether it is decorated.
To summarize, there are three types of window actors:
X11 window actors - directly tied to the backing X11 window. The
corresponding surface actor is directly owned by the window actor and
will never change.
Wayland window actors - gets its surface actor from MetaWaylandSurface
at construction. A single MetaWaylandSurface may create and destroy
multiple window actors over time, but a single window actor will never
change surface actor.
Xwayland window actors - a mix between the above two types; the window
corresponds to the X11 window, and so does the window actor, but the
surface itself comes from the MetaWaylandSurface.
Normally when a X11 window is unmapped, the corresponding MetaWindow is
unmanaged. With Xwayland, this happens indirectly via the destruction of
the wl_surface. The exception to this is windows that are reparented
during changing their decoration state - in this case on plain X11, the
MetaWindow stays alive. With Xwayland however, there is a race
condition; since the MetaWindow is tied to the wl_surface, if we receive
the new surface ID atom before the destruction of the old wl_surface,
we'll try to associate the existing MetaWindow and MetaWindowActor with
the new wl_surface, hitting the assert. If the surface destruction
arrives first, the MetaWindow and MetaWindowActor will be disposed, and
the we wouldn't hit the assert.
To handle this race gracefully, reinstate handling of replacing the
surface actor of an existing window actor, to handle this race, as it
was handled before.
Eventually, it should be reconsidered whether the MetaWindow lifetime is
tied to the wl_surface or if it should be changed to be consistent with
plain X11, as this re-exposes another bug where the X11 client and
mutter will enter a feedback loop where the window is repeatedly
remapped. See https://gitlab.freedesktop.org/xorg/xserver/issues/740.

When using xdg-output v3 or later, the Wayland compositor does not send

When starting a DnD operation, mutter would remove keyboard focus from
the client, only to restore it on the data offer destroy.
However, if the DnD fail, the keyboard focus is not restored, leaving
the user unable to type in the focused window, even after clicking in
the window.
That issue would show only on first attempt, as further DnD attempts
would destroy the previous data offer which would also restore the
keyboard focus.
Make sure we restore the keyboard focus on drag end as well.
https://gitlab.gnome.org/GNOME/mutter/issues/747
On drag start, `data_device_start_drag()` issues a keyboard grab, which
in turn will unset the current input focus.
There is not need to unset the input focus in `data_device_start_drag()`
as this is redone in `meta_wayland_keyboard_start_grab()`
