Sometimes when I try to watch a Youtube video, my main screen seems to crash and end up looking like this. http://imgur.com/YFmRHSQ It only happens to the main one and it only happens when I try to watch Youtube videos. It also doesn't happen every time. I'm using an R9 280X and my card is not running hot. It never happens when running games, even the most graphically-intensive ones. I'm using Chrome so it should keep Flash up to date. I can't find anyone else who has had this problem using Google and I thought someone here might be able to help.
