I have the latest version running on a Dell Latitude 5510 and I'm having random, spontaneous issues with the mouse cursor disappearing while the laptop is in use.
I've discovered that plugging in an external mouse for a few seconds fixes the problem, restoring pointer icon. Sometimes I'll unplug the external mouse immediately or sometimes I'll leave it it. It happens again eventually.
The spontaneous disappearance also happens with the external mouse. Same workaround: unplug it and it resets everything somehow.
P.S. I'm also having the wake from sleep issues here that others are currently reporting.
