I also note that something similar used to happen in Hardy, though I can't recall whether the cursor would flash or not. Note that this doesn't happen every time either, usually only maybe after a few days to a couple weeks. But like one of the other people people here have said, the user will be switched from myself to my wife multiple times per day. So in almost every case, this bug only surfaces after quite a few user switches.
