Evemu recording of a two-finger-scroll down and then up again
Device: ASUS UX301LAA laptop
Linux version: 4.10.6-1-ARCH
Using Gnome 3.22 with default Wayland session.
When upgrading libinput from 1.6.3 to 1.7.0 various functionality of the
integrated touchpad are broken.
Most prominent is the loss of two-finger-scrolling, as attached in an evemu
recording. libinput-debug-events does not record the two-finger-scroll at all,
unlike in 1.6.3 where it was recorded as a POINTER_AXIS event.
Other problems are clicks that are not working anymore when performed at the
bottom of the touchpad, and odd behaviour of the mouse cursor that I can not
describe very well here - it occasionally seems too fast, too slow or just not
moving at all (not sure if related).
No customization has been made apart from Gnome mouse settings.
