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
