Title:
  [amdgpu] Gnome locks up with artifacts on screen

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  With this hardware configuration this issue has been a problem only
  when suspending or resuming from suspend under 20.04. Having decided
  to upgrade through 20.10 to 21.04 to see if things improve enough to
  help me identify which package to report a bug against things have
  become significantly worse.

  With 20.04 it was an occasional occurrence found when returning to the
  computer. Either it was stuck in the suspend process with a blank
  screen or one with artefacts on, or it would start the resume and then
  lock.

  On the upgrade to 21.04 (I didn't stop on 20.10 for more than enough
  time to tidy up and upgrade again), the system seemed improved
  initially - including notably improved boot times (no idea if that is
  related). After a bit of checking things out I went to enable the PPAs
  that had been disabled (Teamviewer, Nextcloud, Anydesk and Chrome -
  all of which have been installed after the problems were initially
  noted). When the window to authenticate popped up the screen filled
  with artefacts and I had to reset. After several attempts to reboot
  into a working desktop variously booting to artefacts, or getting
  artefacts immediately after logging in (usually when opening and
  maximising a terminal to capture the logs for later) I managed to
  change from Wayland to X.Org and logged in successfully with no
  problems for the rest of the day (including a Jitsi meeting lasting
  about 4 hours or more). The next day (today) suspend and resume is
  causing problems as before, boot has slowed down again (again, no idea
  if this is related).

  Compared to 20.04 there are more frequent locks (it had reached one
  every other day, but now it is more frequent - 4 today so far).

  Key things I have noted:

  - it is significantly worse under Wayland (to the point of being unusable)
  - it usually happens during the suspend / resume, but not always
  - when using the desktop it will always related to moving or resizing a window
  - leaving the PC powered off for a few minutes helps to get a reliable reboot 
(as in, if you reboot too quickly you get artefacts immediately after logging 
in)
