A late reply, because I'm now only starting to read month overdue 
mailing lists mails (switching to Thunderbird 3.0 was a bit of a pain). 
I didn't see any solution to your post reported yet, so the following 
might interest you.

A similar problem has been reported in the past, see :

Ping might tell you if that problem has been fixed since then, but since 
it's AFAIK mostly related to the drawing programs it's possible you're 
facing the same problem. See the last link for the solution that worked 
for me, and an example screenshot of the problem at

I definitely remember seeing that same problem on a Wacom tablets 
demonstration booth in 2005, and they were running Windows XP (and 
probably Corel Paint, I can't remember since I didn't stay long after 
noticing they couldn't be bothereed to set their stuff properly). So the 
problem might not be directly related to the Linuxwacom drivers (else 
Ping would have seen it already, nor especially a combination of 
hardware - since I was able to solve that on the same hardware - but 
more a drawing program configuration problem related to tilt. I haven't 
faced this problem personally since then, but I've seen the problem 
talked about during the years on different forums and on the linuxwacom 
mailing lists.
