Screen recording of the problem

SUMMARY

On my primary monitor (AOC CU34V5CW/BK connected with USB-C, to a Lenovo AMD4700U laptop running Fedora 38 with KDE) after some time since system restart visual artefacts are starting to show. This is visible as very fast flickering of parts of the screen (only where there are no windows shown). As soon as a window is covering the desktop, the flickering is gone, when the window is hidden (for instance minimized) the flickering comes back. 

STEPS TO REPRODUCE
1. I can't find a specific step to reproduce, this starts happening randomly after a period of activity (1+ hour since restart)

OBSERVED RESULT
Flickering parts of the screen

EXPECTED RESULT
No flicker
