Please tell me this is a driver thing. Glitches in 3D apps on my editing workstation, starting right after the Radeon Adrenalin Graphics Driver update:

the card isn't new but it's never shown anything like this before... temperatures look normal. I've tried a different cable and the artifacts are the same. I'd like to know what to test before I convince myself it's dead. I also do some photo work on the editing workstation, so I really need to know whether I can trust what I see on screen right now. im about to throw this thing out the window lol
