Same with UXA and vlc with glx output. No compositor here. I can clearly see tearing when I connect the laptop to an external monitor to watch movies. I think there's two bugs being discussed here. One is that compositors that don't unredirect fullscreen windows may give you tearing. Another is that even without using a compositor, and even if you render using OpenGL, you can still get tearing. -- 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
