Description Peter Hutterer 2018-02-07 04:51:34 UTC 
Lifting the stylus out of proximity at the same time as lifting the palm off the touchpad generates some pointer events, usually a button click. This is caused by the in-kernel touch arbitration - after the stylus moves out of proximity the palm is still touching and generates one or two touch events. These trigger a click through the tapping code.

We'll need some workaround with a timer after proximity out before we accept new touches.
