Windows 11 background flickering in/through game

This is a strange one that I’ve never encountered before. My Windows 11 background is flickering through the game. Does anyone know what’s going on?

It’s not happening all the time, it’s happening once in a while and it lasts for less then a seccond, maybe 0.2-0.4 seconds or something like that.

EDIT: Graphic card driver and Windows are both up to date.
