Bug Description
Lenovo Yoga 11S touchpad is jittery. The cursor moves a little even when I try to keep my finger still.
This is noticeable after hysteresis has turned off, but libinput hysteresis was definitely not helping since it made the touchpad unusably numb and unresponsive.
The same jitter happens with the synaptics driver if I turn off hysteresis there. Although synaptics with hysteresis provides a nice experience... seems to be a dramatically lower hysteresis threshold.

I think libinput 1.11.0 or 1.10.3 will contain the fix.
