Same problem on my Dell E7440. with Ubuntu 14.04.3 (installed version). When holding my finger still on the touchpad, the cursor starts jumping back and forth (mainly vertically) from finger location to some random location. Updating to latest BIOS A15, and latest touchpad drivers on 17th August did not help. Problem seems to not happen for the first few minutes after each Ubuntu startup, but then starts happening and becomes quite frequent after about 20 minutes. The problem does not happen with the keyboard trackpoint mouse button.
