<pre>This is the key here:
# Property type 3 (INPUT_PROP_SEMI_MT)
Semi-mt touchpads are those that can only provide us a bounding box of all
fingers rather than the actual position of each finger. In doing so, the
resolution drops to about half whenever a second finger is on the touchpad (the
third finger doesn't provide any position, it's just a bit that there is a
third finger down). We had gestures for a while on semi-mt devices but because
of the resolution issues we removed it, these devices simply aren't capable of
enough precision to make gesture detection reliable. sorry.
so libinput not handling a three-finger gesture on these devices is correct
behaviour.</pre>
