I am using libinput 1.6.0 on Archlinux, kernel 4.9, gnome, wayland. Since update to 1.6.0, tap detection on XPS 13 laptop fails about 50% of times. I had to go back to libinput 1.5.4, which works fine. I guess this is related to the changes mentioned in https://who-t.blogspot.de/2016/12/libinput-touchpad-tap-analysis.html So for me, tap detection is broken with the new algorithm.
