Title:
Intel GPU lockups and graphical glitches in KDE
Status in linux package in Ubuntu:
Confirmed
Bug description:
After a recent package update (at this point, I believe it was a
kernel package upgrade) I began experiencing Intel GPU hangs and
graphical glitches, such as blinking or corrupt textures in the panels
and windows. In dmesg I can see messages like these:
[ 24.825956] i915 0000:00:02.0: [drm] GPU HANG: ecode 7:1:86d2bff9, in
plasmashell [1625]
[ 24.826005] i915 0000:00:02.0: [drm] Resetting chip for stopped heartbeat
on rcs0
[ 24.927993] i915 0000:00:02.0: [drm] plasmashell[1625] context reset due
to GPU hang
