Judging by the timestamps you get regular jitter/wobble but then there's a
pause of ~100ms, just above the timeout that causes libinput to disable the
hysteresis on this device.
We need some smarter approach, i.e. something that analyses the motion for
wobbles and then disables/enables it based on that.
