[Bug 327428] Re: mouse pointer no longer has 1 pixel precision

To reproduce:
Start Gimp and create a new document.
Move the mouse cursor slowly horizontally and watch the column number change. The column number skips every 3rd or 4th pixel . i.e. 9,11,12,14,15,16,18,19,21. The cursor appears a bit jumpy due to the discontinuities.

If xserver-xorg-input-synaptics is uninstalled such that the mouse
driver handles the touchpad, the cursor does not exhibit this behavior,
moving smooth as silk and able to move to every pixel.

Behaves this way in many versions of xserver-xorg-input-synaptics
including all Jaunty versions and the latest.(corresponding to git tag
xf86-input-synaptics-1.1.0)

Running  2.6.29-02062904-generic 64 bit kernel on Jaunty.
