Testing a new NVIDIA card with the NVIDIA driver 280, I think I can reproduce this bug now. It starts off smooth but if I drag windows around for a little while, it becomes jerky. The jerkiness often doesn't go away, but sometimes does if I leave everything idle for a while. Even with the workaround for bug 763005 applied the jerkiness stays.
Now for the good news: This bug appears to be fixed when I install my compiz fix for bug 880707. Awesome :) The bad news: The fix for bug 880707 is undergoing a minor redesign by the compiz team so I can't make it public until that's done. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/888039 Title: Gradual degradation in desktop performance.
