Having the same problem even after the 17.7.1 drivers. I also tried the AMD Clean Uninstall Utility; everything went clean for about and hour until the error appeared again. The only solution I've found is setting the game to DX9 and locking it at 30 frames. This seems to keep it stable but with the loss of frames the game feels sluggish. Playing at DX9 with 60fps or Unlimited causes my screen to go black for a few moments and the game refreshing back in.
