Public bug reported:
I don't know if this has to do with libinput, I'm just guessing.
When using a 2012 Macbook Air the trackpad regularly stops tracking
individual finger movements during use (the cursor stops responding to
movement). Once I lift my finger and once again touch the trackpad it
starts working again, so the symptoms are isolated to a single
uninterrupted touch. Needless to say it is very disruptive to whatever
you're doing at the time.
This occurred seemingly randomly until today when I could deteremine
that I only have to tilt my finger towards me to create a larger area of
contact with the trackpad in order to make it stop tracking. This also
explains why it often appeared to happen right after a click, where I'm
using extra force on the trackpad in order to activate the physical
switch.
The tolerances are apparently much too low, making me lose control of
the mouse cursor extremely often (compared to Windows and macOS, where
it basically never happens). A gradual increase of the contact area
should not result in a complete failure to continue tracking, especially
after the touch has long since been identified as a single finger.
