Thank you for your bug report. I believe that this happens due to the wacom lines in /etc/X11/xorg.conf when using the nvidia binary driver (and for whatever reason only shows up under KDE).
robert-hopt: Could you back up your /etc/X11/xorg.conf file and remove the Section "InputDevice" areas that contain Drive "wacom" and see if there is any difference?
