Hello I have never seen any kind of visual artifacts prior to crashing. Screen just goes blank for a second, comes back and goes out again. Kernel stacktrace in journalctl however looks quite similar to the one pasted in Arch thread. I have installed deb version of firefox and will test if for several days.

It usually happens 2-3 times and then it stays black. Video seems to be running in background (i still hear audio) during screen resets, however I mouse and keyboard are unresponsible. Alt-sysrq-o successfully shuts down the machine. I am using KWin (current git version). The bug does not happen every time, but about once a day. It never happened on 24.04 with 6.8 kernel. Attached is journalctl --system output showing kernel errors related amdgpu/VCN problems.
