Undesired drag after tap
I've found tapping very difficult to use for me, because it starts an undesired drag if I move the cursor right after the tap. However, that's exactly what I do most of the time.
For instance, I tap on a browser tab and move the cursor immediately inside the tab. With libinput, I have to force myself to wait a bit after the tap to avoid the drag, which is quite inconvenient.
Under OSX (which I come from), drag after tap is disabled by default. If I want to drag, I'll use the physical button on my touchpad.
I'm using a Dell XPS 13 9350 with libinput 1.1.3 + Xorg. I've attached an evemu recording of a single tap + move which triggered an undesired drag.
