Was happening to me too. For me it's not %10-20 of the time, it's more like after about an hour of normal use then for a period of 5 minutes then it goes away until it comes back in another hour. I was thinking it might have been the differences in processor power, but I'm on a i7 920.
The CPU usage is 'weird' when it happens. According to htop the different processors get random highish (%50-80) cpu usage but it doesn't max any of them out and no process in the list is listed as using much (other than Xorg which is around %20). Also after it happens, when I try to playback using totem is throws up 5 error boxes about being 'disconnected' but then works fine if I quit and reopen it. I'll try and grab the actual error if it happens again. I'm thinking it might be pulse-audio or gstreamer related although maybe some media backend crashing is just a symptom of the problem. I have since reinstalled, not sure if this fixed it or not. Seems it might have improved it somewhat though. -- User interface stutters / laggy when mouse NOT moving https://bugs.launchpad.net/bugs/661327 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
