This machine is an HP Envy x360 touchscreen hybrid laptop. On upgrade from 15.10 to 16.04, multiple finger touches / gestures no longer perform actions in the user session as they did before. This includes the unity window controls.
I believe as well that pinch used to work when running Google Maps in Chrome -- this now also fails. I don't know if it's possible that means it's a symptom of another problem. I'm not sure what tools at https://wiki.ubuntu.com/Multitouch/Testing are actually current or useful right now, as there are some broken links and un-maintained packages there, but I'm happy to follow guidance on how to help nail down the problem.
