Jittery mouse

Playing Cube 2 the other day, I noticed when I move the screen seemed unsmooth; jittery and unpleasant. Immediately suspecting my ATI GPU, I tweaked a load of graphical settings. Nothing.

Then I noticed that when I move using the keyboard only, no problem at all. Any movement of the mouse causes jittery, slightly jerky rotation of the camera.

Any ideas on how I could smooth it out? It is an old microsoft optical mouse I guess, might get a new one.

I might take a stab at writing my own, I've messed with the engine before.

I'm on Ubuntu Linux 9.10 with 2GB of ram and a 512MB ATI Radeon HD4670

I have the same problem since I checked out the updated the SVN branch today.
Before I didn't have this problem.
The problem dissapears when I disable shaders. My laptop isn't very good at fillrate or shader heavy games, but there has been a noticable performance hit in the latest SVN revisions for me.

Geforce 8800 laptop mobile thingy...
Drivers are 2 months old or so.

Tried that, even the lowest settings till suffer from it.

Only happens when I move the mouse. Are there any X11 options or Linux software I could use to smooth out the input?

if there is a problem and u want it fixed, you have to find the specific svn revision which caused the breakage.

Just a fyi,

For me these issues were fixed since I last checked out the SVN branch yesterday.

Could it perhaps have something to do with the mouse sampling rate?
I've had a similair problem with UT2004 once that I solved by upping the mouse sampling rate and lowering the sensitivity.
