This is only a very partial work-around though, only applicable to video, and only if played through a player supporting vaapi or gl output. - How do I tell my flash game to render with vaapi? - How do I tell firefox's html-5 video renderer to use gl? - How do I tell my window manager to render with either gl or vaapi (yet keeping compositing disabled)? (i.e. I'd like tear-free windows movements, too) There are more use-cases for basic v-sync support other than just being able to watch a simple video! In other news, I just noticed something: for some reason my video's were tearing even when using the vaapi and gl outputs just now. This was with kernel-3.4+drm-intel-next-2012-05-20. Toggling the resolution with xrandr fixed it. I don't know how or why it stopped working, but now if/when this happens you should at least be able to fix it without a reboot. -- 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
