I suspect the cause for this is more the natural shape of your finger.
as you press down, the contact surface increases, and the hotspot you
get is somewhere in the middle. as you release, the contact surface
changes and you get the jump. I can see this here and it's related to
how hard you press before releasing. the harder, the bigger the jump.
there isn't really anything you can tune in the settings for this
particular behaviour. the hysteresis options will help a bit, but
hinder some smaller movement. really what we need here is some
pressure-based smoothening, to prevent cursor jumps if the pressure
changes.
I now increased the pressure threshold. Just for the archives, I am
using the following settings:
Option "FingerHigh" "55"
Option "FingerLow" "50"
This is high enough to stabilize the mouse position on the end of mouse
movements significantly. The downside is that I am missing an
occassional click here when I tap to lightly.

Thanks, that's great. If this patch is added, will we still need to
manually set a dead area on the buttons? Or is there a possibility to
change the default config files so that if there are clickpad buttons,
those are automatically marked as "dead area"?
Cheers,
Markus
