I have the dell XPS 9360.
I'm facing a touchpad problem,
after of approximately hour of using, the touchpad stack like more than one finger touching the pad (when only one finger touching it).
it causing the computer to make a gestures like scrolling, switching to another apps, and zooming in and out when moving only by one finger (because it thinks that more than one finger touching it).
The only way to overcome this, its by touching the touch screen, and after a while (few minute) the problem come back again.
I tried to update the drivers, reinstall the operating system (win10), and the problem still persist.
I would recommend adding your experience to this open bug on the Dell Sputnik project to increase the awareness to this widespread issue:
