Title:
[i915] Noise-like lines of graphics corruption when moving windows in
Xorg sessions
Status in linux package in Ubuntu:
Triaged
Status in linux source package in Groovy:
Fix Released
Bug description:
== SRU Justification ==
[Impact]
Noise-like lines of graphics corruption when moving windows in Xorg
sessions.
[Fix]
Revert "UBUNTU: SAUCE: drm/i915: Synchronize active and retire
callbacks".
[Test]
Daniel van Vugt confirmed reverting the commit fixes the issue.
I can also reproduce the issue on one of my system, I can confirm it
fixes the issue too.
[Where problems could occur]
Race condition the commit solves may appear again.
The commit was reverted and replaced by an upstream fix, which is already
included in 5.8. So it should be rather safe here.
== Original Bug Report ==
I left my desktop (T480s thinkpad docked to ThinkVision P24h-10)
unattended for a while, and then got the error message and now have
funny lines on activity, e.g. red lines flashing on top of gnome-shell
bar when switching windows, or white blocks/lines around typing text.
This is the second or third time it happened, reboot fixes it until
the error pops up again.
