At least once a day if I play a video, on a web page or a video player everything freezes in gnome shell, after the video has played for a few seconds.
The sound carries on, if I switch to another terminal and
pkill -HUP gnome-shell
Then switch back, everything is unfrozen and I can see the video - the whole time the sound from the video never stops.
I've reproduced the bug using chromium and firefox to play videos remotely, vlc and totem to play videos locally.
On Ubuntnu 13.04
