I get the same black flash screen at times, usually when looking at system settings and file explorer etc..
I think it is something to with either the AMD drivers or Win 11..
Before upgrading to the latest Recommended drivers, I didn't get the flashes..
This is in the driver notes:
- Brief display corruption may occur when switching between video and game windows on some AMD Graphics Products, such as the Radeon™ RX 6700 XT.
I don't get this happen, but makes me think that it is related somehow..
