wow, that is quite unusual. The touchpad's range is actually smaller than the
range it announces, usually it's the other way round.
Find the file 60-evdev.hwdb on your system and follow the instructions at the
top to save this hunk as local hwdb entry. Then restart and check if the
behaviour improves. If the hwdb entry applies correctly, evemu-describe should
show the new axis ranges.

EVDEV_ABS_01=1114:4764:67
EVDEV_ABS_35=1270:5659:49
