** Description changed: == 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. - However it was to solve the issue on 5.4, and the race could already be - solved on 5.8. + 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.
