[Bug 757294] [NEW] YouTube full-screen freezes the screen, forcing hard reboot

[Mads Peter Rommedahl]

Public bug reported:

Binary package hint: firefox

I often play YouTube videos in full-screen, but sometimes when going
full-screen in Natty, at some point, the video kind of gets "stuck" on
the screen. It continues to play fine to the end, but pressing Escape
doesn't exit out of the full-screen, and by pressing other buttons I can
sometimes see flashes of some of the windows that are in the background
- but I can't exit out of the damn full-screen video and am forced to do
a hard reboot.

This doesn't happen every time I go full-screen in a video though. But
in the last two days, it has happened twice. Last time was with
http://www.youtube.com/watch?v=saStFjCBQE0&feature=relmfu

I have previously had issues with my graphics card (an ATI Radeon 5700)
on the Natty beta, so it's possible that it may be related to the
graphics drivers. But for now I'm assigning it to firefox since that's
the app it's happening in.

I've attached some Apport stuff about Firefox just in case.
