Public bug reported:

Binary package hint: xserver-xorg-video-intel

I just upgraded from Kubuntu 9.10 via 10.04 and 10.10 to 11.04-dev.
Since 10.10 the mouse sometimes "stutters" while moving, freezing for a
few hundred milliseconds. Similar behaviour has been reported for
Maverick before (#595764, #599068, #662946, #658747), however in these
cases it seems to have been limited to i8xx GPUs while I use an i945...
Additionally, I could not find reports of this problem re-occuring (or
still occuring) in Natty, so I'm reporting it here.

The mouse stuttering / short freezes are much better than with Maverick,
where even the sound was affected, but it's still pretty noticeable and
annoying / distracting.

Using "top", I noticed a kernel thread called "kworker" being listed
among the top-5 processes in the process list refresh following such a
"mouse stuttering".

I'm not sure if any further information is neede, I'm happy to provide
whatever I can to help resolve this problem.
