Public bug reported:

After upgrading to Karmic recently,  I found serious image tearing
during video playback. The tearings mostly occur at the upper part of
the screen, especially when there is a horizontally moving object in the
video. Perhaps there was also video tearing when I was using Jaunty, but
not obvious enough. I've tried to set "Sync to VBlank" in nvidia-
settings and compiz config settings manager, and also the correct
refresh rate in compiz, but none helped. I included a screenshot to show
the tearing problem. Note that I only see the tearings marked with red
in video playback, the tearings marked with blue only appears in
screenshots.

When metacity is used instead of compiz, the tearings are still there.
And I tried nvidia drivers 173,185,190, the results are the same. Later
I found by disabling composite in xorg.conf, the tearing is gone. But
then I won't be able to use compiz. So I think the problem lies in
composite extension of nvidia driver.
