I have a Dell XPS 13, 9360, running 16.04. Tapping with three fingers switches me to another app, reliably and reproducibly.
The real problem is that I get switched to another app while I'm typing - the bases of my hands must rest on the touchpad in a similar way.
This happens even though I have "Tap to click" disabled.
For now, I have disabled my touchpad entirely - this is the only way I can type on my laptop without the window switching (at least when I use the laptop on a table - having it on my lap changes my angle a little and makes the problem slightly less prevalent).
