Oh no, you seem to have installed graphics packages from the 'oibaf'
PPA. That PPA is known to cause bugs like this and is unsupported.
Please remove the PPA from your system completely, and then report a new
bug if the flickering persists.

Bug description:
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.
