Comment 3 for bug 218322

I am posting to say that the same has just started to happen on my system.
I just noticed it today, although my last major update was about a week ago, when I also installed the new banshee-1 player.
The problem appears as stated above, on either banshee-1 (which I was using when I noticed it) totem, and vlc.
I have metacity composite enabled. Cannot deal with compiz. I have the dreaded Sis card.
If I disable compiz, then everything works fine.
This problem doesn't seem to affect Mplayer though, which displays videos sharply whether composite is enabled or not.
Is there a difference in the way mplayer draws video vs totem/vlc/banshee-1?

Attached, fine my lspci
