--- Comment #101 from Peter Hutterer <peter.hutterer at who-t.net> ---
For the record, the patches in Comment 99 change things around again. First
version was to disable the hysteresis after a series of events that looks like
the touchpad is reliable. That didn't work, because touchpads are terrible.

Second version (current in git master) changed to enable the hysteresis if
wobble is detected. That didn't work but it's unclear if that's a bug, patches
1-3 of the patchset may eliminate that issue. Nate, can you please test this?

Third version, i.e. comment #99 now simply doesn't touch the hysteresis and the
wobble detection merely warns the user that something is up. We then have to
add a device-specific hwdb entry to set the fuzz for the value the device needs
and libinput can pick it up on the next run. I'd rather avoid this because it's
reasonably insane, so it mostly depends on whether patches 1-3 are enough.
