Public bug reported:
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.
