Also, when the laptop enters sleep mode after being inactive for a while the screen flashes the same way, even on the desktop after i log in. This can be fixed by changing the screen's refresh rate from 120hz to 48hz and then back to 120hz.

When i reach the desktop the flashing stops. Still, having the screen flickering on the log in screen is very annoying. As far as i can tell, the laptop doesn't have any further screen issues. Thanks in advance!
