Same problem on my thinkpad t440s. I think I've pin-pointed what's going on. Tapping in two separate locations on the trackpad very quickly in succession registers as if you have put your finger down in the first location and swiped it to the second location, thus causing the cursor to move as if you swiped rapidly. I tied messing with all the synaptics settings but no luck. Juans fix works, but you lose a lot of the nice feel of synaptics settings.
