OK, the fix is available for testing in ppa:vanvugt/compiz. But I highly recommend you also use ppa:vanvugt/unity because it contains a critical related performance fix.
In my testing (with both PPAs) this resolves all tearing in 24-30 FPS video, and almost all tearing in 60 FPS video. It's really getting close to the limit of how many pixels compiz can push around :) ppa:vanvugt/compiz | https://launchpad.net/~vanvugt/+archive/compiz compiz (1:0.9.6+bzr20110929-0ubuntu6vv5) oneiric; urgency=low * Significantly reduced tearing even more. This now resolves the tearing seen during HD video playback (LP: #755841) This also dramatically improves GL benchmark results for those who like to measure framerates with sync-to-vblank disabled. -- Daniel van Vugt <vanv...@gmail.com> Wed, 07 Dec 2011 17:54:09 +0800 ppa:vanvugt/unity | https://launchpad.net/~vanvugt/+archive/unity unity (4.24.0-0ubuntu2b1vv4) oneiric; urgency=low * Fix major performance regressions due to unnecessary UnityFBO binding (LP: #861061) (LP: #880707) UnityFBO was being bound even when not required. This caused major lag in glPaintOutput, which slowed down all rendering. This was seen in reduced framerates in apps (LP: #861061) and significantly worse screen tearing with Unity 4.x compared to 3.x (LP: #880707). -- Daniel van Vugt <vanv...@gmail.com> Sat, 03 Dec 2011 14:34:01 +0800 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/755841 Title: [sandybridge] Graphics tearing when playing video To manage notifications about this bug go to: https://bugs.launchpad.net/compiz-core/+bug/755841/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
