[Bug 661327] Re: User interface stutters / laggy when mouse NOT moving

 

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.
