Comment 32 for bug 395476

Found a workaround for this bug that has been around for an eternity.

- Go to Applications , ubuntu software center
- download Gnome MPlayer
- open Gnome Mplayer
- Go to : edit, preferences, set video output to ''x11''.
- Gnome Mplayer will be your one and only video player from now on.

This workaround doesnt seem to diminish performance.

For me, the bug seemed to appear when I downloaded ''MPlayer Plugin for Mozilla''
None of the other solutions worked permenantly without diminishing performance (video lag).

Good luck.
