It's hard to describe what is going on and I didn't think to take a picture of it when it happen. But I believe it's somehow linked to when I launch Marvel Heroes (Steam) since both times it happen that game was open. But my second monitor became a collage, of I think it was only the first display, scattered all about. I tried to screen cap it but the screen capture showed what SHOULD have been there. This happen to me twice so far and I had to log out or restart each time it happen, closing all programs did nothing.
If it happens again I'll take a picture of it and submit it to this thread.
