The speed is now fixed indeed, but scrolling is now subject to the
same "dirty mouse" bug. See the "badscroll.rec" file in the attached
archive. It contains two scoll gestures - one down, and one up. The
driver has picked up only the beginning of the up-scroll (i.e. the
chromium window was not scrolled as far as I wanted, even though I
continued moving both fingers).

Actually the first tap after the server start is detected reliably.
The problem only affects other taps. See the file "tap-libinput.rec"
in the attached archive.
