This appears to be the result of xwl_cursor_confined_to() and
xwl_screen_get_default_seat(). While not against protocol, mutter ends
up sending xdg_output before wl_seat. xwl_screen_get_default_seat()
makes the naïve assumption that we always have a valid seat, we end up
returning a pointer to the empty list itself instead of an actual seat
and causing ourselves to segfault.
So, actually return NULL in xwl_screen_get_default_seat() if the seat
list is empty, and skip any pointer confinement processing in
xwl_cursor_confined_to() when we don't have a seat setup yet.

This is a rare occurrence of a crash in Xwayland for which I don't have

The backtrace looks as follow:

#1 abort () from /usr/lib64/libc.so.6
#2 OsAbort () at utils.c:1361

#11 WaitForSomething () at WaitFor.c:219

The crash is caused by dereferencing “xwl_pixmap->buffer” in
xwl_glamor_pixmap_get_wl_buffer() because “xwl_pixmap” is NULL.
Reason for this is because the corresponding pixmap is from the root
window and xwayland is rootless by default.
This can happen if the window was mapped, redirected, damaged and
unredirected immediately, before the damage is processed by Xwayland.
Make sure to remove the dirty window from the damage list on unrealize
to prevent this from happening.

The xdg-output protocol aims at describing outputs in way which is
more in line with the concept of an output on desktop oriented systems.
For now it just features the position and logical size which describe
the output position and size in the global compositor space.
This is however much useful for Xwayland to advertise the output size
and position to X11 clients which need this to configure their surfaces
in the global compositor space as the compositor may apply a different
scale from what is advertised by the output scaling property (to achieve
fractional scaling, for example).

If an X11 app draws a little here, some there, and a tiny bit in the

However, we cannot blindly send an arbitrary number of damage
rectangles, because there is a risk of overflowing the Wayland

The install rule of Xorg.wrap is currently a dependency of the
install-data target instead of the install-exec target. The build also
uses install-exec-hook to change the ownership and set the SUID bit on
the Xorg.wrap binary. The problem is that install-exec-hook is only
ordered respective to the install-exec target, the rules of install-data
may or may not have been executed.
If install-exec-hook runs before the Xorg.wrap binary is in place,
a message similar to the following will be present in the build log:
chown: cannot access '/pkgdir/usr/lib/xorg-server/Xorg.wrap': No such file or directory
make[6]: [Makefile:1151: install-exec-hook] Error 1 (ignored)
All that needs to be done is to change the name of the program variable
to contain 'exec' for the install rule to depend on the install-exec
target.
Excerpt from the Automake manual, chapter 12.2 The Two Parts of Install:
"Any variable using a user-defined directory prefix with ‘exec’ in the
name (e.g., myexecbin_PROGRAMS) is installed by install-exec. All other
user-defined prefixes are installed by install-data."

#define SISCHECKOSSSE /* Automatic check OS for SSE; requires SigIll facility */

Which means it has never worked in any modular server release.
A less gross way to do this is to check for SSE support with getauxval()

only if the context is already indirect.
However, that's a statement about Mesa's libGL (and anything else that
inherited that bit of the SGI SI more or less intact). Nothing prevents
a mischeivous client from issuing that request of a direct context, and
