I have the exact same problems as you with my XFX RS 480 4GB card, I tried latest drivers 16.12.2 as well as 16.12.1, same problem with both drivers.
Usually happens when I watch a stream on twitch. Havent happened when I was playing.
I also get those weird images followed up with a bluescreen Video_TDR_Failure.
Is this a driver issue or is something wrong with my card?
Still having these issues with Crimson Relive 17.1.1
