The only mouse pointer problem I've experienced in F13 is that the mouse 
pointer goes playing hide and seek ( bug 537065 ) on only one of my 
monitors.
from time to time.

However I know of a touchpad on one old German laptop ( I think it was 
branded Medion or something ) that experiences weird behaviour similar 
to what you describe and couple of interesting intel based graphics 
twirks which I unfortunately dont have in my possession or unlimited 
access too to file bugs to get those things FIXED or at least look at.
