evemu-record output
My touchpad, with libinput enabled, feels too sensitive in a way that even a
slight movement of my finger affects cursor position. That makes touchpad
extremely uncomfortable to use because when I move my finger a cursor makes
annoying jumpy movements in the process which makes precise cursor movements
almost unachievable.
* Down below you can see one part of `libinput-debug-events` output. I was
moving my finger diagonally up and right, but you can see that libinput detects
negative x acceleration. I believe in this moment there is a significant cursor
jump.

I've also added evemu-record output as attachment in case that helps at all.
* OS: Arch Linux
* libinput: 1.3.2
* `touchpad-edge-detector` results:
Touchpad ETPS/2 Elantech Touchpad on /dev/input/event16
Move one finger around the touchpad to detect the actual edges

Touchpad sends: x [0..3260], y [0..2282]</pre>
