two-finger scroll up
There is a very noticeable delay between start of two-finger movement and an
actual scroll event. This doesn't happen on X11 with synaptics driver.
I'm using Lenovo Thinkpad T440 (OS: Arch, Gnome/Wayland, libinput version:
1.5.0-1).
Attachment is evemu recording in which i place two fingers and move up.
