I am not clicking the "software button area" and trying to move this finger. On
Thinkpad X220, I have physical left, right and middle buttons.
See this image:

So what I am doing is clicking this separate hardware button, and simply moving
a finger on the touchpad.

> libinput swallows any motion from a finger "pinned" to the software button area. that's a feature, but in this case it's a bug - there is no good solution here. libinput supports two fingers though, so you can click with one finger and then put another finger down to move. tricky on a x220 with it's small touchpad, but I don't think I'll change the behaviour, the side-effects are just too big.

Funny thing is that this works on my X220 when using the software button area.
I didn't even know of the existence of this area (since it is much more
practical to use physical buttons).

Anyway reopening the bug report since it is about the hardware physical buttons
which don't work with libinput, and not the software button area.
Since they are separate hardware, I don't think there are any side effects
here.
