This seem to only affect a virtualbox fedora 41 workstation guest that I use for testing. I did update on a couple other physical hosts with amdgpu and they seem fine.
If I revert to a previous snapshot that is on the previous mesa 24.2.8-1 all is fine.
Thank you for the information, I didn’t think to search for “black screen” on the forums. I’ll poke around in the mesa issues tracker and see if something as been reported.
Just an FYI, I have created an issue with mesa #12447, with the backtrace from the gnome-shell core. There are a few similar issues that are still open, so this may be a duplicate of one of those.
