[Dwayne Litzenberger <dlitz@xxxxxxxxx>]

Public bug reported:

When using a touchscreen, xserver generates incorrect RawMotion events
when some of the axis values have not changed since the last event.

This is for evdev with absolute positioning.

The bug is *not* present in the Debian xserver-xorg-core (2:1.7.7-13)
package.

[I will edit this bug with more information shortly -- dlitz 2011-11-01]
