running ubuntu 13.04/kde 4.10 on my laptop (kernel 3.8/ ddx 2.21, ivybridge). kwin still tears at the top of the screen even with sna enabled and vsync on in kwin, but I assume thats just this bug: https://bugs.kde.org/show_bug.cgi?id=307965
So I tried disabling vsync in kwin and using the tearfree option which did remove all tearing, and seems to perform reasonably well for desktop usage and video playback (haven't tried anything else) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/755841 Title: [sandybridge] Graphics tearing when playing video Status in Compiz Core: Fix Released Status in Ubutter: Making Ubuntu buttery smooth: Fix Released Status in X.org xf86-video-intel: In Progress Status in “compiz” package in Ubuntu: Fix Released Status in “xserver-xorg-video-intel” package in Ubuntu: Fix Released Bug description: Binary package hint: xserver-xorg-video-intel Videos tear heavily.
