evemu-record on Fedora 24 (libinput 1.3.3)

Reopening, as two-finger scrolling is still jumpy on Fedora 24 (even if one
finger moves are OK). One thing I noticed is that while scrolling up, when the
top finger reaches the top of the touchpad, the view suddenly scrolls down.
Looks like when the top finger is no longer detected, the driver thinks it has
moved to the position of the one at the bottom. See the attached evemu-record
log, in which I just move my two fingers up until that jump happens.

This is with libinput 1.3.3-2.
