Hi Eloy,

Thanks for the info.  I'm currently working on a more permanent fix in
Compiz in which I will "blacklist" known GPU's that are affected by
this.

There shouldn't be any performance penalty when running with X11 Sync
turned off.  What that is supposed to do is keep the GPU's rendering in
Sync w/ X11.  Many folks over time have been affected by issues where
the rendering is done out of sync resulting in weird artifacts on the
screen such as black borders and such.  See bug #269904 if you want more
details.
