Public bug reported:

1 out of 20-40 clicks on the touch pad results in a pointer jump and a
"random" click.

Hard to reproduce, but mostly happens when I use my middle finger to
move the cursor and click with index finger. Sometimes the double touch
of middle/index finger is interpreted as mouse move, the jump is more or
less the same distance as if i had moved the index to the middle finger
position.

Cheers
