I'm getting flickering/glitching on the desktop in Windows 10 on driver 19.11.1 - also had the problem on the previous (non-beta) drivers.
Everything is fine when in games, it's just when using things like Firefox, Spotify etc.
At first I thought it might be a problem with my undervolt on the GPU, however it does the same at the default settings.
I also have two monitors - one at 144hz and one at 60hz. The problem persits even if I set both screens to 144hz.
2700X, Gigabyte Gaming 7 WifFi X470, Radeon VII.
Any solutions, I read elsewhere that this a known issue? It's very very annoying!
