scan_visible_region() scans through each value of a uint8_t array and checks
whether that value is 255. Right now it always checks one value too much
though, resulting in a buffer overflow. Fix that by checking the array
bounds before actually accessing the array.
Found by running gnome-shell with address sanitizer and starting
GIMP.

Both GRAB_OP_KEYBOARD_MOVING and GRAB_OP_KEYBOARD_RESIZING_* are
defined as GRAB_OP_WINDOW_BASE with FLAG_KEYBOARD set, but the
latter have additional bits set to indicate the direction.
That is, the GRAB_OP_KEYBOARD_MOVING bitmask cannot be used to
differentiate between move- and resize operations. Instead,
check that no direction bits are set.

The unknown color space's only purpose is to signal that the current KMS
state has a unknown color space set. It is not one of the color spaces
that can be set. We already only try to set a color space if the default
color space is supported so we should use the default color space as a
fallback instead of the unknown color space.

With the move away from GTK3, and the indirect dependency on GTK4
grown in the GNOME Shell side, we've indirectly gotten a small sneaky
behavioral change: The GTK4 library will, right on dlopen, get
DESKTOP_AUTOSTART_ID for itself and delete it from the environment.
This happens before our own X11 session management code is
initialized, which confuses the hell out of it, into thinking
initialization is actually shutdown, gnome-session does not follow
along with this request, which leaves GNOME Shell into a confused
startup state where it never calls SmcSaveYourselfDone() and grinds
startup to a halt until gnome-session decides to move things forward.
In order to fix this, get the DESKTOP_AUTOSTART_ID before we lend
control to GNOME Shell bits and GTK4 is possibly initialized, and
feed it directly to our X11 session manager bits.

We might get told to restore the old monitor configuration by the
monitor configuration prompt, in case the user pressed "revert" or
equivalent. This might be in response to a button press, and those
happen during frame clock dispatch. If we would restore an old
configuration during dispatch, it means we would reconfigure the
monitors including their stage views while dispatching, which means we'd
destroy the frame clock while it's dispatching.
Doing that causes problems, as the frame clock isn't expecting to be
destroyed mid-function. Specifically,
We'd enter
clutter_frame_clock_dispatch (clutter-frame-clock.c:811)
frame_clock_source_dispatch (clutter-frame-clock.c:839)
g_main_dispatch (gmain.c:3454)

g_main_loop_run (gmain.c:4448)
meta_context_run_main_loop (meta-context.c:482)
main (main.c:663)
which would first call
_clutter_process_event (clutter-main.c:920)
_clutter_stage_process_queued_events (clutter-stage.c:757)
handle_frame_clock_before_frame (clutter-stage-view.c:1150)
which would emit e.g. a button event all the way to a button press
handler, which would e.g. deny the new configuration:
restore_previous_config (meta-monitor-manager.c:1931)
confirm_configuration (meta-monitor-manager.c:2866)
meta_monitor_manager_confirm_configuration (meta-monitor-manager.c:2880)
meta_plugin_complete_display_change (meta-plugin.c:172)
That would then regenerate the monitor configuration and stage view
layout, which would destroy the old stage view and frame clock.
meta_stage_native_rebuild_views (meta-stage-native.c:68)
meta_backend_native_update_screen_size (meta-backend-native.c:457)
meta_backend_sync_screen_size (meta-backend.c:266)

Normally, mutter implicitly allows a window being shown to take
focus. This is normally desired, except it steals input from
GNOME Shell self. Avoid focusing the just shown window in those
situations.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2878>
When a X11 application is started, typically what happens is:
- A startup notification token is created, with a _TIME%d suffix
- The application being spawned receives it through the environment
- (dbus piping, maybe)
- The application replies the startup notification token, and
fetches the timestamp from it
- The application makes a _NET_ACTIVE_WINDOW client message request
with this timestamp
- Mutter handles this client request and activates/focuses the window
Prevent this last step if windows are not interactable (e.g. there is
a compositor grab) and ignore the focus request. This specifically
applies to X11 clients requesting focus themselves, and unlike previous
approaches, doesn't try to prevent focus changes that do come through
interaction with Mutter/GNOME Shell.
This should only break if applications do not observe _NET_ACTIVE_WINDOW
and perform XSetInputFocus on themselves, but in that case the X11
keyboard focus is stolen from our hands already.

This is the mask that lets us receive among other events the rather
important CreateNotify, that tells us about new winows. This has went by
rather unnoticed except for cases where multiple windows show up very
quickly directly after the frames client spawned, because the drag icon
surface cache eventually already did select that particular mask.
Make things more reliably by explicitly setting the mask for the events
we rely on to function.
This fixes flaky stacking tests that map multiple X11 windows in a row.

2d8fa26c8e ("core: Pass "frame action" grab operations as an

the "constrain_titlebar_visible" constraint.
The fact that it wasn't applied before was relied upon by some
extensions. While it should arguably exist a better API that for such
extensions to use that have a bit more predictable behavior, until that
is so, restore the old semantics.

Linear sampling can influence the value of surrounding pixels beyond
the scaled framebuffer extents calculated during stage view rendering,
resulting in flickering graphical artifacts due to unaccounted pixel
changes. This is exhibited in xfreerdp and wlfreerdp at 150% display
scaling.
Fix this by ensuring that all pixels that may be affected by linear
scaling is included in the framebuffer redraw clip by padding the actor
redraw clip.

The existence of the KMS property just means that we can send an

Allows to prepare KMS updates to set the color space and HDR Static
Metadata on the output.
For some reason we need ALLOW_MODESET on commits which change the HDR
Static Metadata InfoFrame on AMDGPU. There is no technical reason why
one needs to mode set to send an InfoFrame and the driver should just
manage without ALLOW_MODESET. Until this is resolved in the kernel we
just prepare KMS updates which might mode set.

This adds a new 'experimental-hdr' string property to the MonitorManager
which can be changed from looking glass.
Currently when the string equals 'on', HDR (PQ, Rec2020) will be enabled

transfer functions and color spaces as well as HDR metadata can be
added.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2879>
The color space and HDR metadata are eventually sent as metadata to the
display. The color space informs the display of the colorimetry of the
frames we produce, the HDR metadata informs the display of the transfer
function and additional mastering display colorimetry and luminance to
guide tone and gamut mapping.
The only color spaces we support right now are the default color space
and Rec bt.2020 which is typically used for HDR content. Other supported
color spaces can be added when needed.
The default color space corresponds to whatever colorimetry the display
has when no further changes are made to the calibration of the display.
The colorimetry is communicated to sources via EDID/DisplayID.

A Wayland client repeatedly requesting activation of its surface using
the xdg-activation protocol would make mutter constantly update the
cursor.
To avoid needlessly updating the cursor back and forth between busy and
default, add a timeout to delay the update.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2849>
When a client (either Wayland or X11) is started, the window activation
will update the cursor to the "busy" cursor.
Mutter will then set the X11 cursor on the X11 root window to match that
so that X11 applications which do not explicitly set a cursor inherit
from that default (busy) cursor.
Updating the X11 cursor too often can hammer the X11 connection and
cause a deadlock with Xwayland.
Reload the X11 cursor in a later handler to avoid that issue.

When an onscreen is "attached" it means it has an active CRTC and output
it interacts with, e.g. listens to configuration changes to update gamma
and privacy screen state.
MetaOutput and MetaCrtc are rather short lived objects meaning they are
disposed of and regenerated each time the compositor reloads monitor
resources, and while MetaOutput are indirectly kept alive due to the
MetaMonitor holding on to them during reloading, the same does not apply
to MetaCrtc, so to avoid trying to disconnect our signals from
disappeared outputs and CRTCs when we dispatch, hold our own references
to these objects.

As implemented in colord 1.4.6, cd_icc_load_handle() has three possible
results:
1. success, taking ownership of the profile;
2. failure because cmsGetProfileContextID returns NULL, *not* taking
ownership of the profile;
3. failure in cd_icc_load(), taking ownership of the profile.
The previous commit ensures that we are not in case 2.
In case 3 where cd_icc_load() fails, ownership was already given to
the colord CdIcc object, so it will be freed when the g_autoptr unrefs
the CdIcc, and we must not free it again: that would be a double-free,
potentially resulting in memory corruption.

We want to avoid using too high scales too easily, which started to
happen 2f1dd049bf ("monitor-manager: Rework default scale factor
selection"). Instead of using the closest non-fractional scale, which
effectively is what we'd do, only round upwards if we're closer than
0.25 (25%).
Since there are some wiggle room for scales to make the logical
resolution on the integer pixel grid, make sure to compensate. This
compensation is done by adding an extra 0.2 to scale difference.
For example the following fractional scales will get these corresponding
integer scales:
* 1.25 -> 1.0
* 1.5 -> 1.0
* 1.75 -> 2.0
* 2.0 -> 2.0

In order to make things more and more asynchronus and to each time we
paint be an isolated event, that can be potentially be applied
individually or together with other updates, make it so that each time
we draw, we use the transient MetaFrameNative (ClutterFrame) instance to
carry a KMS update for us.
For this to work, we also need to restructure how we apply mode sets.
Previously we'd amend the same KMS update each frame during mode set,
then after the last CRTC was composited, we'd apply the update that
contained updates for all CRTC.
Now each CRTC has its own KMS update, and instead we put them in a per
device table, and whenever we finished painting, we'll merge the new
update into any existing one, and then finally once all CRTCs have been
composited, we'll apply an update that contains all the mode sets for all
relevant CRTCs on a device.

Instead of using the "discarded" page flip callback when the
"discarding" happened during actual immediate processing, communicate
the same via the KMS update feedback.
The "discarded" page flip callback is instead used only for when a

on shutdown, while in the simple backend, this also happens when a
asynchronous retry sequence eventually is abandoned.
This allows further improvements making KMS handling fully async.

We test direct client buffer scanout using a TEST_ONLY commit on atomic,
and with various conditions in non-atomic, but if we end up failing to
actually commit despite this, handle the fallout asynchronously. What
this means is that we'll reschedule a new frame immediately.
For this to work, the same scanout buffer needs to be avoided for the
same CRTC. This is done by using the newly added signal on the
CoglScanout object to let the MetaWaylandBuffer object mark the current
buffer as non-working for the onsrceen that it failed on. This allows to
re-try buffers on the same onscreen when new ones are attached.
This queues a full damage, since we consumed the qeued redraw rect. The
redraw rect wasn't lost - it was accumulated to make sure the whole
primary plane was redrawed according to the damage region, whenever we
would end up no longer doing direct scanout, but this accumulation only
works when we're not intentionally stopping to scanout. For now, lets
just damage the whole view, it's just an graceful fallback in response
to an unexpected error anyway.

This is intended to be used only for plane assignment, and CRTC like

Surfaces belonging to a screen-casted window should always be considered
visible even if they are not visible on any stage view - be it because
they are on a different workspace, minimized or occluded.
Doing this in an optimal fashion is highly complex right now -
interdependent with (and somewhat similar to) ClutterClones. Thus treat
stream-casted surfaces similar to those with clones, with the small
difference that even a fully invisible surface still gets a primary view
- the fastest one. This ensures that clients never refresh too slow for a
screen-cast, at the cost of sometimes refreshing too fast.
The later only happens on certain multi-monitor setups and should thus be
acceptable.

There is an increasing number of cases where we want the frame callback

After !2489, the active workspace's MRU list is now used to pick
the next focus window instead of the stack order.
This list is currently only updated on focus, which can lead to
surprising behavior when closing a window after activating its
ShellApp in the shell.
That is because raising a window (as part of shell_app_activate())
will only change the stacking order, so when closing the active
app window, the focus will switch to whatever had focus before the
app was activated, not the app's next window.
In order to allow gnome-shell to address this, add a new
raise_and_make_recent() method that also adjust the MRU order.

With detach meaning having the onscreen stop listening on configuration
changes on the corresponding backing mode setting objects. We need to do
this as there is a time between rebuilding the views, and that the new
mode sets are called, where the old onscreen is kept alive, but the
stage view is gone. At this point in time, if privacy screen or gamma
configuration changes, e.g. by the night light temperature changing, the
onscreen would attempt to schedule an update on the now gone stage view.
This commit also renames the "keep onscreen alive" to "detached

For the coordinates of pointers or stylii, we translate the ones we store
using the viewport matrix already. For touch events otoh, we store coords
untranslated and translate them later only for event emission.
Let's be consistent here and store the coordinates of touch events
translated, just like we do for pointer events.
This fixes touch window dragging on rotated monitors. MetaWindowDrag calls
clutter_seat_query_state(), which uses those stored coordinates. So in case
of a touch sequence the coords returned by query_state() would be
untranslated.

In the case where we early-out from meta_window_drag_begin(), the
effective_drag_window might not be set yet. In this case, we might finalize
the object before effective_drag_window is set, leading to a NULL pointer
when accessing window->display in hide_tile_preview().
To avoid that crash, add a check whether the window is set already. If no
window is set, we can just skip hiding the preview anyway.

Streams are generally recoverable by the client and errors may happen
e.g. on negotiation failures. Right now we close the stream and
corresponding session, which is neither necessary nor expected by
clients.
Just disable the stream instead and let clients handle things as they
seem fit. This allows clients to e.g. try several Gstreamer pipelines
with limited caps on a single stream.

Doing it in dispose means the backend is actively tearing down itself,
meaning various components might or might not be there, depending on how
the tearing down is implemented. Make things a bit more robust by doing

Reading upon the history of this code branch (commits 6891ce95dc
and 7a4c808e43 are most relevant), it seems this code is meant to
synchronize Mutter focus state taking the Xserver state as true.
That is, if Mutter tried to change the focus but something truncated
that action, Mutter focus will be changed to be in sync with the
Xserver again.
This sounds backwards in a Wayland session. Mutter focus should be
the canonical source, and not second-guessed from the current Xserver
focus window. These race conditions might still apply between X11
clients, so make these paths only apply in that case.
An example of this breaking can be reproduced with a Spotify and
Firefox window, moving the focus from the first to the second by
going to the GNOME Shell overview in between, and clicking the
Firefox window from there. The Firefox window will be raised, but
refuse to take focus.
It's unclear what made this an issue recently, perhaps commit
0e6395d932 since the now possibly ignored XI_FocusIn/Out events
affect this accounting of the Xserver focused window. Anyhow it
sounds better to ignore these paths for Wayland/native altogether.

The intention when the offset request was added to protocol was
that the attach request in a new enough protocol version should
require dx/dy to be zero, but ignore them otherwise.
The current code checks for 0, but then overwrites the existing
dx/dy with it, which renders an earlier wl_surface_offset() call
ineffective.

This protocol is intended to let special clients create transient-for
relationships between X11 and Wayland windows. The client that needs
this is xdg-desktop-portal-gnome, which will create e.g. file chooser
Wayland dialogs that should be mapped on top of X11 windows.

When modal dialogs are attached, and we set the parent/transient-for
after setting the modal type, the attachedness isn't updated. This is
(apparently) not the case for X11 windows, as they go through a
unmanage/manage dance avoiding the issue.

The script is a list of newline separated command lines that are sent to
the client one by one as if one would have used e.g.

The service channel D-Bus interface aims to be a "back door" for
services that needs special casing in Mutter, e.g. have custom private
protocols only meant to be used by that particular service.
There are currently no special casing implemented; only the basic
service channel infrastructure is added. There is a single method on the
interface, that is meant to eventually be used by
xdg-desktop-portal-gnome to open a Wayland connection with a private
protocol needed for the portal backend's rather special window
management needs.
The service channel Wayland client works by allowing one instance of
each "type", where each time needs to be defined to work in parallel. If
a new service client connects, the old one will be disconnected.
MetaWaylandClient's are used to manage the service clients, and are
assigned the service client type.

One can add a wl_global filter to a wl_display instance, which can be
used to decide what clients should see what globals. This has so far
been used to limit a Xwayland specific protocol extension to only
Xwayland. In order to expand the logic about what globals are filtered
to what clients, introduce a filter manager and port the Xwayland
specific protocol filter to this new manager.
Tests are added, using a new dummy protocol, to ensure that filtering is
working as expected.

This API creates a "client" then later sets up a wl_client and returns a

On X11, the stage itself is backed by an XWindow, and moving the
input focus elsewhere will bypass any Clutter-level grabs.
This effectively allows newly opened windows to steal the focus
from gnome-shell itself, which is clearly undesirable. To prevent
that, only allow moving the X11 focus to a Window when no grab is
in place, just like commit 50e89e376 did for the stage focus.
But particularly the updating of x11_display->focus_xwindow is not
prevented. Since it's more consistent to the MetaDisplay/MetaX11Display
dual focus tracking and across Wayland/X11 backends, ensure the X11
input focus is actually set on the last focus Window after the
grabs are gone and windows became interactable again.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2832>
This patch unfortunately results in situations where it is intended
that the focus change happens while a grab is present (e.g. Alt+tab
popup), resulting in confused focus state.

different level.

Windows that are decorated may get configure requests before
the frames client created a corresponding frame window and Mutter
reparented the window.
Since the configure request results in the buffer size being
used to update the window size and the window does not have a
buffer yet, these requests could mistakenly result in the client
window being given a minimal size.
In these situations, do not use the buffer size but the given
size. The window still has to undergo frame creation and
reparenting before being shown for the first time.

This used to be implicitly done by popups using a META_GRAB_OP_WAYLAND_POPUP

the keyboard focus.

surface is looked up from the focused MetaWindow.

On one hand, this used to be handled generically in all the paths that
changed the MetaWaylandPointer focus surface, induced by user interaction
or not.
On the other hand, just listening for crossing events is not sufficient
since those also do happen programmatically. We must only listen to
crossing events that have a physical source device, meaning this was
created through user interaction.

Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2828>
On Wayland sessions, this handling is unnecessary and even prone
to confusion (e.g. crossing serials are only ignored in X11-exclusive
paths, so this handling competes directly with that in MetaWaylandPointer).
Avoid it entirely there, so MetaWaylandPointer can figure out
sloppy/mouse mode focus for all Wayland/Xwayland surfaces.

In GTK this is only used for GTK clipboard/DnD selections, and
finding out whether there is a compositing manager in charge.
In Mutter, we manage our own clipboard/DnD selections, and don't
perform any rendering through GTK in the Mutter process.
So there's no special reason to let these events go through GTK,
and (related to xwayland-on-demand?) there may be race conditions
in the handling of the second feature.
There's a chance this race condition may be in Mutter, but it
does not sound worth to chase this race condition when we can
let GTK ignore these events. And it does not make sense to "fix"
gtk3 for this Mutter-only condition, when we intend to eventually
avoid it.
So, take the easy path and ignore these events.

bind_output() creates output interface resource, but does not
set implementation for it when wayland_output->monitor is NULL.
However, when the wayland library is running wl_closure_invoke(),
it expects the implementation to be non-NULL, and if not, it just
segfaults mutter by NULL pointer dereference.
This commit tries to address this issue by setting an implementation
when wayland_output->monitor is NULL. This could help prevent crash

The previous logic tried to keep the position of the top left corner of
the window relative to the top left corner of the monitor. This allowed
the window to move out of the target monitor. This change keeps the
proportions of the distance between the window and the monitor borders
instead if possible. Otherwise it keeps the relative position of the
center of the window clamped to [0,1] to make sure the window lands on
the right output.
This also slightly changes what monitor is considered to be on: the
monitor which contains the center of the window and, if the center is on
no monitor, the monitor wich overlaps the most with the window.

While completely untested, at least this makes it work "in theory"
again. Before it'd listen to signals on the stage, but have an incorrect
type signature to handle the test paint procedures, meaning it'd
probably crash or cause memory corruptions.
What was needed was a signal which in the callback the test could call
some cogl functions to paint on the framebuffer. While there is no such
signal on the stage, and the ClutterActor::paint signal (which they
probably used in the past) is long gone, lets add a "test actor" that is
just a wrapper that adds that paint signal with a paint context.
The tests that need it are changed to add this actor to the stage, and
to listen to the paint signal on the actor instead of incorrectly
listening on stage signals.
