I think this is the crash being reported in impish live sessions but the core files keep getting truncated so it's hard to tell. See also bug 1940532.

It seems to be any gnome-shell Xorg session hitting this crash on exit... but for most people a Xorg session will only ever be used in the live image.

Still affects libX11 in Live session (build 20210929), which I am currently testing.

Same thing:

segfault at 0 ip 00007f-------77f sp 00007ff--------0 error 4 in libX11.so.6.4.0[7f-------000+8c000]

Can attach detailed logs if required.

Yes the function at the top of the stack is in libX11, but libX11 has nothing to do with the root cause of the crash which is just gnome-shell.

no longer affects:

mutter (Ubuntu)

Not all gnome-shell crashes are this one, and in fact there are zero reports of this one (so far) after 40.5-1ubuntu1 in https://errors.ubuntu.com/problem/11d90a7db51d11df7d99a6ef6e5aa31eb678d273

Please open a new bug for each crash file using the ubuntu-bug command.
