This sounds like a bandwidth management issue, which I know Linux
doesn't do as well as Windows (on Intel graphics either).
Firstly you seem to have the wrong (old) kernel still installed. It
should be version 5.19 so please try fixing that with:
sudo apt install linux-generic
or
sudo apt install linux-generic-hwe-22.04
and reboot.
If the problem persists after that then please run:
journalctl -b0 > journal.txt
lspci -k > lspci.txt
and attach the resulting text files here.

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.

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