            Bug ID: 99588
           Summary: Tap detection fails 50% of time with libinput 1.6.0
           Product: Wayland
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: libinput
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: dom at dosc.net

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.
