I have the same problem. One easy way to spot this is to watch the credit roll-up at the end of movie, you will easily notice the stuttering. Personally I have a core i3 graphics with intel open source driver.
Here is one way to avoid this stuttering while keeping Compiz on (works for me) : 1- Open CompizConfig 2- Enter OpenGL menu 3- Disable sync Vblank 4- Close CompizConfig 5- Open a video Is this workaround working for you guys? -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/780007 Title: [Natty] Stuttering video playback To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/780007/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
