I just started "git gui", when the notebook froze for a few seconds. Afterwards, I could access most running applications, but chrome only rendered the tab bar, and plasmashell would not start again.
I had only just updated the KDE libraries from 5.44.0 to 5.45.0 when this happened. Not sure if this is related.
[ 6202.821326] [drm] GPU HANG: ecode 4:0:0xefdcfff7, in chrome , reason: Hang on rcs0, action: reset
[ 6202.821327] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[ 6202.821328] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[ 6202.821329] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[ 6202.821329] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

Hello. Could you please provide more information about your software?
glxinfo -B with mesa version would be great. Right now there are about 5 tickets about GPU hangs in kde plasmashell on different distributives, so maybe it is one issue...
Please let me know if you need more information.
