With Tap-and-drag gesture disabled and even tapping disabled (although this does not change anything) when one finger touches the touchpad and another taps the very edge of the touchpad (any side), the system behaves as if there was a click and hold action as long as the finger is on the touchpad. This seems to be linked to the driver reporting a left click when the second finger touches the veery edge of the touchpad, see output from evtest below. How to replicate: disable tapping. On the desktop, put one finger on the touchpad, then lightly tap the very 1mm of the edge. Move the first finger down and right and notice an area being selected. This should only happen when the finger is pressed (like for a click) against the touchpad and held so during the move. Attached are outputs from synclient and xinput. I believe it is a bug in a kernel driver.
