Since upgrading to Fedora 41, I’ve noticed that on my main machine with an amdgpu-based video card (Radeon RX 6650XT) that gnome-shell crashes upon locking my screen with the following error in dmesg:
[Thu Dec 19 15:35:27 2024] gnome-shell[2748]: segfault at 555349765229 ip 00007fe654e54bf9 sp 00007ffdbbeb9b60 error 4 in libgio-2.0.so.0.8200.2[24bf9,7fe654e30000+11d000] likely on CPU 8 (core 16, socket 0)

I did not have these problems under Fedora 40, and my other machine that I upgraded (a small Intel N100 NUC with i915 graphics) does not have these problems coming out of screen lock.
This same problem was also found in a Debian message thread: https://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg2003938.html
I have the MUTTER_DEBUG_KMS_THREAD_TYPE=user workaround in /etc/environment as well as mcbp=0 being passed to the amdgpu driver.
Anyone else have this same problem? If you got past it, how? Or is this indeed a bona fide bug in gnome-shell?
