The window might be retained in the damage list after
`xwl_screen_post_damage` in certain conditions. This means we need to
check if the window is already in the list to avoid adding the same
window twice which will lead to list corruption resulting in server freeze
in `xwl_screen_post_damage`.

(cherry picked from commit 711d491729)
Leasable displays do not have any actual associated Wayland output and
are not available to regular X11 clients and left entirely to the
application who requests the lease.
As these are not actually managed by the Wayland compositor and left
entirely to the "lessee" application, the viewporter protocol required
for the XRandR emulation is not usable on such devices.
We should therefore not advertise the XRandR emulated modes for those
leasable displays.
This also solves a problem with implementations of glXGetMscRateOML()
which is used notably by Chromium/Electron. Applications using this
which will begin lagging/stuttering exponentially over
time, trying to look up a non-existent mode with 0x0 as returned by
XF86VidModeGetModeLine() with XRandR emulation for such devices.

Commit 8a5f3ddb2 ("set tag on our surface") introduced the use of tags
to differentiate our own surfaces, and commit a1d14aa8c ("Clear the
"xwl-window" tag on unrealize") removed the tags before the surfaces are
actually destroyed.
Xwayland would then rely on these tags on the surface to decide whether
to ignore or to process the Wayland event in various places.
However, in doing so, it also checked for the tag on keyboard leave
events.
As a result, if the keyboard leave events is received after the X11
window is unrealized, keyboard_handle_leave() would not queue the
LeaveNotify events for the DIX to proceed, and the key repeat would
kick in and repeat the key event indefinitely.
To avoid the issue, process events regardless of the tag as before
in keyboard_handle_leave().

X11 and Wayland requests are unordered, causing a race in the X11 window

To mitigate that race, delay the wl_surface destruction by 1 second,
so that the compositor has time to establish the association before the

WL_SURFACE_ID X11 property set.
This is only a mitigation though, a more robust solution requires a

(cherry picked from commit e37f18ee97)
Because of the design of most Wayland compositors, where the compositor
is both a Wayland server and an X11 window manager, any X11 client
issuing a server grab (i.e. XGrabServer()) can possibly hang the whole
desktop when Xwayland is running rootless.
This can happen with e.g. ImageMagick's import command with mutter.
1. "import" is launched and issues an XServerGrab(),
2. Xwayland restricts access to that "import" X11 client alone,
3. mutter continues to process events until it needs to sync with
Xwayland (there's variability in time before the hang occurs),
4. When mutter does an XSync() (explicitly or implicitly through some
other Xlib call), it will stop waiting for Xwayland to reply,
5. Xwayland waits for the XServerGrab() to be released by import,
6. "import" waits for a user input to release the XServerGrab(),
7. mutter is stuck waiting on Xwayland and does not process input
events...
To prevent this, re-route the GrabServer/UngrabServer requests and
pretend the grab works but actually does nothing at all for all clients
but the X11 window manager (which can still issue X11 server grabs, at
its own risks).

When the pointer leaves an X11 window, and enters a Wayland native

generate the wrong crossing events to another X11 window instead.

compare the Wayland focused surface with the X11 window found in the
window tree.
Commit 59ad0e6a ("xwayland: Fix use after free of cursors") changed the
logic in sprite_check_lost_focus() to use IsParent() to compare the

The composite overlay window (COW) can be queried from any X11 client,

If a client tries to get the composite overlay window, the Xserver will
map the window and block all pointer events (the window being mapped and
on top of the stack).
To avoid that issue, unset the "mapped" state of the composite overlay
window once realized when Xwayland is running rootless.
Note: All Xservers are actually affected by this issue, but with most
regular X servers, the compositing manager will take care of dealing
with the composite overlay window, and an X11 client using
GetOverlayWindow() won't break pointer events for all X11 clients.
Wayland compositors however usually run Xwayland rootless and have no

Xwayland may open a fair amount of file descriptors for passing Wayland

As a result, Xwayland may hit the (soft) limit of file descriptors
leading to a Wayland protocol error and the termination of Xwayland.
To mitigate that risk, raise the limit to the maximum (hard) limit of
file descriptors (unless of course the limit was set explicitly from the

support for drm-lease-v1.
In order to not deadlock with the Wayland compositor if its response
to a lease request is delayed, the new interface in _rrScrPriv
introduced in the last commit is used, which makes it possible to
block the X11 client while a response is pending.
Leasing normal outputs is not yet supported, all connectors offered
for lease will be advertised as non-desktop.

Add a new interface to _rrScrPriv to make it possible for the server to
delay answering a lease request, at the cost of blocking the client. This
is needed for implementing drm-lease-v1, as the Wayland protocol has no
defined time table for responding to lease requests.

This was overlooked when converting the function to use libxcvt.
Bring back name initialization from old code.
This was causing a segfault in xf86LookupMode() if modes where
name is NULL are present the modePool list.

The compositor may send us wl_seat and its capabilities before sending
e.g. relative_pointer_manager or pointer_gesture interfaces. This would
result in devices being created in capabilities handler, but listeners
not, because the interfaces weren't available at the time. So we
manually attempt to setup listeners again.

The implementation is relatively straightforward because both wayland
and Xorg use libinput semantics for touchpad gestures.

Currently, when given the choice, Xwayland will pick the GBM backend
over the EGLstream backend if both are available, unless the command
line option “-eglstream” is specified.
The NVIDIA proprietary driver had no support for GBM until driver series
495, but starting with the driver series 495, both can be used.
But there are other requirements with the rest of the stack, typically
Mesa, egl-wayland, libglvnd as documented in the NVIDIA driver.
So if the NVIDIA driver series 495 gets installed, Xwayland will pick
the GBM backend even if EGLstream is available and may fail to render
properly.
To avoid that issue, prefer EGLstream if EGLstream and all the Wayland
interfaces are available, and fallback to GBM automatically unless
“-eglstream” was specified.
With this, the compositor, given the choice, can decide which actual
backend Xwayland would use by advertising (or not) the Wayland
"wl_eglstream_controller" interface.
This change has no impact on compositors which do not have support for
EGLstream in the first place.

Add (verbose) statements to trace the actual backend used with glamor.
That can be useful for debugging.
