Public bug reported:

Binary package hint: xorg

When I attach a second screen to my Thinkpad T61 and activate TwinView
using the "Nvidia X Server Settings", the my touchpad becomes more
sensitive to horizontal movements and less sensitive to vertical
movements.

To demonstrate this, I cut a circular hole in a piece of paper and put
it ontop of the touchpad. Using Gimp, I followed the circular boundary
using the brush. The result is attached. Without TwinView (black), I
almost get a circular shape. However, the aspect ratio for my attempt
with TwinView (red) is clearly not 1.
