Bug ID: 106044
Summary: Unreliable tap-to-click on a DELL XPS 9370
Product: Wayland
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: libinput
Assignee: wayland-bugs@lists.freedesktop.org

evemu recording of a missed tap
I have a pretty new DELL XPS13 9370 laptop and using tap-to-click my touchpad
is missing clicks every now and then (like, 1 every 5 or 6). It happens a lot
more often with 2-finger or 3-finger tapping. I suspect this is due to the
touchpad recognizing my finger moving during the tap, but it happens way too
often to be normal (it NEVER happens on Windows with the same hardware and I
think I use my touchpad in the same way regardless of the operating system).
Attached is a evemu recording of a missed tap.
Other than this I'm happy to report that the touchpad works pretty well
(scrolling, palm rejection, accuracy...).

libinput version 1.10.4 on Manjaro linux
