On the Pi3 I've come across an issue in build #0913 - and quite a lot of other revisions back - where after I had created an additional couple of user profiles and after switching user the mouse cursor seems to either disappear completely(visually - function still works) or theres a garbled box that takes up a chunk of the screen.

I did a clean install using the installer and faced the same issue, and again as I patched up through versions.
