I noticed the same bug in mutter 40, then tried to bisect it and found
the same in mutter 3.36. So yeah this appears to be a new kernel (or
Mesa) bug. It doesn't seem to happen much if at all if you run gnome-
shell. Only in mutter for me.
** Bug watch added:
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.

Please test latest drm-tip kernel:

If the issue is not fixed upstream, please file an upstream bug at intel
graphics:

Thanks for the video. Corruption of that type is usually a kernel
problem only. I can't imagine any way in which mutter can cause that
one...
Please try some older/newer kernels.

I use Xorg, and almost exclusively see it on my external monitor. After
locking the screen and having it locked for a while. Saw it once on the
internal one in a week, but like daily on external.

... so if mutter 3.38.1 does not resolve the problem, I would be
interested to see the corruption in action. Probably with a video.

Also adding a gnome-shell task. This happens on 5.8.0-21-generic from
proposed too, and restarting gnome-shell stops the corruptions, so it's
possible this is a gnome issue.

The corruption also happens in build
5.9.0-050900rc4drmintelnext20200915-generic but the error in dmesg does
not, and it's less, it only happens on window management actions (switch
window
Surprisingly with that, restarting gnome-shell actually fixes the issue
(it did not with normal kernel).

Attached dmesg from journalctl. To the best of my knowledge, this is all
that's missing, as apport now has no raw dmesg access anymore and missed
to upload the dmesg.

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
That said, hmm, it took an hour or so after the backtrace for it to
cause visual distortion or I misremember, or it gets worse over time.
