I've built the input-work branch. There is no more saw tooth pattern appearing
on slot 1. Without the libinput patch scrolling works better than it worked
with the old kernel, but just as Hans said it's smooth at first, then it jumps,
smooth again, then it jumps and so on. With libinput patch scrolling is always
smooth. I've attached evemu-recording of 2 finger scrolling with the custom
kernel.

One more thing that's bugging me is now that scrolling works great, I've
noticed that there's a delay between me starting a scroll gesture and the
scrolling actually happening on the screen. That's mostly noticeable when slow
scrolling. I've tried measuring the distance required for me to move the
fingers on the touchpad until scrolling starts, and it's somewhere between 3
and 5 mm. But after scrolling starts, any movement on the touchpad will result
in scroll gesture. I have another problem with tapping, but I'll report
separate bug for that.
