When I have a youtube video playing in one tab, and I'm looking at another tab and bringing up a notepad text file or Spider Solitaire, the youtube video will imprint itself over the upper left corner of my screen and won't go away unless I refresh the desktop (solves it for a few seconds) or move the youtube tab away from the actively playing video. It doesn't happen with every video. Here's two where it affects me. http://www.youtube.com/watch?v=zBQVsJbM6e8 http://www.youtube.com/watch?v=Ui0WU0QcE3M Does anyone know what's causing this?
