[Bug 1896091] Re: [i915] graphic corruption following orkqueue: PF_MEMALLOC task 131(kswapd0) is flushing !WQ_MEM_RECLAIM events_unbound:active_work [i915]

Oh, drmtip exists too, I thought you said drmnext which was stuck on
09-18 (and I tested 09-15 which was more stable but not perfect). I'm
currently just running the 5.9.1 mainline kernel for testing purposes,
which so far (2 days in seems stable), but might just break later today,
who knows.

Title:
[i915] graphic corruption following orkqueue: PF_MEMALLOC task
131(kswapd0) is flushing !WQ_MEM_RECLAIM events_unbound:active_work
[i915]

Status in linux package in Ubuntu:
Confirmed
Status in mutter package in Ubuntu:
Incomplete

Bug description:
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.
