Comment 58 for bug 224475

Actually, the laptop I had tested on as well had it freeze as well. The audio will continue on as normal but the current video frame will freeze. As soon as you exit fullscreen it will go back to normal. I figured it was just because I was using the dumpy 64 bit version so I didn't mention the fact. It does this with compiz. If I use metacity then all functions well (though the screen flickers a little bit).

 But it does adjust the volume fullscreen!
