Comment 41 for bug 151674

The CompizConfig solution works great in 10.4. I set [X] Sync to VBlank, and Refresh Rate=60 Hz in ccsm, and the problem goes away. It even persists across reboots. (I have run with compiz disabled for a long time, because of some compatibility issue, but this is enough to make me switch it on for video playback.)

I did not find this bug when I was frantically troubleshooting this issue a few months ago. I think the solution should be put on a wiki page as a temporary measure, to make it easier to find. I don't have time to put it there now, maybe later.

Thanks for the fix, it made my day!
