I've been playing since beta, and for some reason I'm getting glitches from time to time (the whole screen turns to one random colour with a LOT of perfectly spaced vertical lines) which lasts for like a tenth of a second. After half an hour to four hours though, the entire screen freezes up with the same glitch, my PC becomes unresponsive but any sound playing will continue and I can still talk to people on skype/TS. I'm running a R9 280x + 7970 GHz crossfire, and when I disable this I can play for longer before the freeze occurs, but no amount of reinstalling of game or drivers (or beta drivers for that matter) has fixed this. I've also got an i7 3770K if that matters at all, and all hardware are running stock, no overclocking.
Pls halp
