Recording of the problem (starts somewhere around E: 11.8)

libinput loses track and completely stops responding during two-finger
scrolling.

If I'm scrolling with the tips of two fingers, sometimes my fingers stick and
skip, raising from the glass briefly. They definitely leave the touchpad for a
split second. But when I put them back down, I get zero response to my
scrolling. I have to stop trying, raise both fingers again and lower them again
to get any response at all.

This doesn't seem to be a touch size threshold problem since I was able to
reproduce it even with 2:1.
