Comment 18 for bug 151674

Hi,

@ Gaspard : Curiously, compiz is not the problem for me,

- turn off compiz via [Visual Effects] in [Appearance Preferences]
- reboot PC (or restart X)
- videos/graphics _still_ show screen-tearing

In my case, Compiz doesn't seem to be the cause. The only way I could get rid of
the tearing was to disable my 2nd monitor in [xorg.conf] (see my previous posts).

Everyone seems to point the finger at Compiz. I think its something to do with X.
However, nobody else has confirmed or replicated my 2-monitor problem scenario.

Also, this screen-tearing is not limited to just videos. It happens in graphics
applications as well. I do a lot of OpenGL programming for my assignments, and
anything drawn in the GL-context window screen-tears as well. Even when I'm
rendering some simple triangles and with [Sync to vblank] turned on.

Hope this helps.
