Today I installed my new R9 390 (1015 core clock version), my specs are 4770k, GA‑Z87X‑UD4H, 16gb ram. The issue I'm having is when I shut off a game or alt/tab out of the game I get a flash of color, mostly purple. Running 1080p. Reminds me of back in the day when you would switch input between a VCR and TV. I had the new Crimson drivers installed, but that stuff is making FO4 run badly. So I backed down to the last CCC beta drivers. It doesn't do it every time and it almost acts like the faster I alt tab, the less likely I will see this. The card I removed today is a Vapor X 7970 Ghz and I never had this issue with that card. Is this the way the 390 or XFX cards, or is this a card problem?
