Just another observation - when my palm of the right hand touches the touchpad while using the touchpad, the touchpad behavior seems normal; also, when I place my left palm on the area to the left of the touchpad, the behavior seems also normal. However, as soon as I move my left hand away from the touchpad area, and I lift my right palm from the laptop, with only my finger(s) touching the touchpad, the behavior becomes erratic again.
So in a nutshell: It works when at least one palm touches the metal of the area to the left or right of the touchpad; it does not work when only a finger (or two) touches the touchpad itself.

When holding a single finger on the touchpad, without moving my finger, the cursor jumps around like crazy, and even performs clicks. When placing a second finger on the touchpad, without moving either, it gets even worse. See desktop recording clip as reference of the behavior (attached as out.ogv). The laptop is an Asus ZenBook UX31E.
