Public bug reported:

Binary package hint: xorg

Over time, my mouse pointer becomes more and more erratic and
unresponsive.  It never becomes unusable, but it gets jerky and hard to
use.  If I run 'top', I can watch Xorg CPU usage spike in direct
correlation to how much I move the mouse around (and the mouse
performance gets worse while I'm doing this).  If I wave the mouse
pointer around a lot, CPU will reliably hit 100%, and the pointer will
be far behind my physical gestures with the mouse (and will continue to
move for a while after I stop moving the mouse).  CPU climbs back down
after I stop moving the mouse.

When I first log in, everything is fine.  This problem gets worse the
longer I stay in the same X Session.  I haven't tried logging out back
to GDM and logging back in; if you need me to I can try that.

Switching between windows / desktops is also increasingly sluggish.

This is all on  Ubuntu lucid (development branch).

I don't know if this is related to any of these bugs:
