Updated from quantal-proposed on Intel sandybridge graphics, went to the youtube clip via guest account -> no tearing.
** Description changed: [Impact] Tearing on some drivers in some video applications. [Test Case] Use intel graphics and run http://www.youtube.com/watch?v=ZCPkOpMHB7g in - full screen mode. + full screen mode. No tearing should be spotted. On ati graphics same + test can be done by downloading the clip and using mplayer -vo x11 -fs + -zoom clip.mp4. [Regression Potential] None, restores current behavior for the specific applications as a driver/application workaround. --- Using "Unredirect Fullscreen Windows" can cause significant tearing in the fullscreen window being unredirected. This is an unavoidable consequence of "Unredirect Fullscreen Windows". Removing compiz from the equation and allowing windows to render directly to the screen means compiz has no control over the window and cannot prevent tearing any more. Workaround (1): CCSM > Composite > Unredirect Fullscreen Windows = OFF -or- Workaround (2): Check the settings of the application running fullscreen. It should have an option called something like "sync to vblank" which you can enable. If not, use a different app. ** Tags removed: verification-needed ** Tags added: verification-done -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1051802 Title: "Unredirect Fullscreen Windows" can cause significant tearing on fullscreen windows (especially playing video) To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1051802/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
