if you see KEY_F23 then that's a hardware issue. something isn't initialized
correctly by the kernel, libinput doesn't generate those by itself.

is the touchpad detected as a touchpad or just as a mouse-like device? If the
former, you'll have to enable tapping, libinput has it disabled by default.

an evemu-record of a scroll sequence should tell us what's going on there.

yeah, that's correct and is the expected behaviour. TOUCH_FRAME is needed to
group frames. either way, short answer here is: touchscreen gestures like
tap-to-click is something that needs to be performed on the client-side, i.e.
in the application. recent GNOME3 should do this but otherwise it depends on
the toolkit.
