<pre>right, so the touchpad only supports 2 finger touch positions (max slot is 1,
i.e. 2 slots), the third finger can be detected but not placed on the touchpad.
This will improve with the RMI4 patches scheduled for the kernel (you may then
run into <a class="bz_bug_link
bz_status_NEW "
title="NEW - Multi-touch is pretty picky on finger placement"
href="show_bug.cgi?id=99830">Bug 99830</a>).
For now, what's likely happening here is that the first two fingers detected
are vertically too far apart (there's a threshold), so libinput guesses that
it's a pinch gesture and then goes with that since it cannot tell where the
third finger is. This is fixable, but I probably won't have time for it in the
near future, let me know if you want to have a go at this.</pre>
