This way, I see no tearing.
I have no tearing on GL in fullscreen. I do, however, have tearing for very simple GL code in windowed mode (fill window black, flip, fill screen white, flip - tearing is painfully obvious), mplayer -vo gl in both windowed and fullscreen mode (since its "fullscreen" is actually a screen-covering window and doesn't trigger the same mechanism), and mplayer -vo xv in all modes. This is with all compositing turned off *and* using a window manager that doesn't support in anyway, by the way. vaapi might possibly work, but mplayer doesn't support it. (I know about the mplayer-vaapi patch; it hasn't worked with modern mplayer(2) code for some time, sorry.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
