If I plug my 175 hz screen and a second 60 hz screen I often get a freeze and then a black screen, after the black screen I get a message that the AMD drivers crashed and all my applications with Hardware Acceleration crash. The crashes happen even without any app with software acceleration open. If I only have one screen plugged the drivers never crash.
GPU: 7900 XT
CPU: Ryzen 7 3800X
None of my screens have freeSync or anything like that active.
