This isn't too surprising. XGL doesn't currently sync screen updates to vertical redraws so it is quite possible that you might get tearing if things aren't being redrawn extremely quickly. Another alternative explanation is that there is a bug within the nvidia binary drivers but either way I don't think this is going to be a high priority bug...

James M:
Does setting __GL_SYNC_TO_VBLANK as described in the link you gave help?

Setting to needsinfo pending reporter's reply.

Thank you for your bug report. As generic compiz as now been uploaded to Feisty (compiz-quinn is now known as beryl), we need to see if your bug is still present. If you can test the version of compiz in feisty (1:0.3.3-0ubuntu2~git2006112 or later) and tell us if you bug still exists, please do. Please make certain you are using Ubuntu's Xorg as well. We also require the make of your video card, to help debug driver issues. If you are using a newer ATI card (x1000 series or newer), please indicate so. To get this information, please attach /var/log/Xorg.0.log
