Sporadic flickering glitches on Ryzen 6850U, Radeon 680M

Brief summary of the problem:

A while after booting, i get flickering artifacts, mostly on the left side of the screen. They occur approximately every 20-60 seconds, and only last for some fractions of a second. They look similar to the artifacts show in the attached video in #2192, but are not that regular, and sometimes span a larger area of the screen.

I have not found a good way to trigger them by a specific action, but they seem to occur more often when e.g. switching tabs in Firefox or hovering over the file tree in vs-code until a tooltip appears. But this could also be coincidence, as they also appear when watching videos with mpv in fullscreen.

Switching between Xorg and Wayland does not make a difference, and i also tried switching from KDE to xfce.

However, while kernel versions 6.0, 6.1 and even 6.2.rc2 show the glitches, it seems that version 5.19.13 is not affected, I have not seen a single glitch with it.

Screenshots/video files

Since the glitches are not easily triggerable i was not able to take a video of them yet.

Log files (for system lockups / game freezes / crashes)

I can't see any driver/gpu related errors in the logs.
