--- Comment #2 from Peter Hutterer <peter.hutterer at who-t.net> ---
ok, so replaying this with evemu shows the jumpy movement. it almost behaves
like it's only running at a couple of frames per second.

First a question though: what are the phys. dimensions of the touchpad. Is the
vertical resolution really wrong?

>From a quick manual skim of the event recording it looks like events still come
at the normal sampling rate (80Hz) but the average movement is somewhere around
50 device-units (i.e. almost a mm). So the sensor resolution must be pretty
awful.

Hans, do you know of any kernel tweaks that may be missing here or do we need
to work around this in libinput somehow?
