Daniel, thanks for the suggestion!

This is quite possibly a duplicate of https://gitlab.freedesktop.org/drm/amd/-/issues/2352.

I'm evaluating the suggestion to add "amdgpu.dcdebugmask=0x10" to the kernel boot parameters. That parameter seems to disable PSR, see below.

➜ ~ sudo cat /sys/kernel/debug/dri/0/eDP-1/psr_state
0
➜ ~ sudo cat /sys/kernel/debug/dri/0/eDP-1/psr_capability
Sink support: yes [0x03]
Driver support: no [0xffffffff]

Kernel package: Ubuntu linux-oem-22.04c, current version 6.1.0-1008-oem.

I'll report back in a few days to see if this indeed fixes the flickering.
