Public bug reported:
alienware aw3423dwf flickers when set to 165hz. Doesn't at 100hz. Works
fine under windows. GPU is Radeon 6950XT. If I change refresh rate down
to 100hz it's fine.
Happened on 22.04 LTS, and the amdgpu ppa made games not work, so I
upgraded to 22.10 instead.
Description: Ubuntu 22.10
Release: 22.10
I expect the display not to flicker at 165hz. monitor doesn't lose sync,
it's just like a few pixel wide bar that runs the width of the screen
that shows up randomly for a fraction of a second. Happens when just
using the desktop environment, not sure if it happens when playing a
game.

99% sure I should be under X11, not wayland.
