After running Skyrim for about 30 mins or so straight, I start to get these occasional small blue squares that quickly flash on the screen, usually in a corner of the screen. I have an HD 7870. My GPU isn't overheating, as it typically hovers around 70 degrees C under load. I also ran DxDiag and it says no problems detected. I tried playing BF3 for a while to see if I had this issue in that game, but I didn't. This leads me to believe it's a Skyrim exclusive issue, though I could be wrong. Anyone else have this problem? I'm using the current AMD 12.6 drivers also.
