I had the similar disappearing wireless mouse cursor in Ubuntu 14.04. Just started happening about 2 weeks ago. I'm usually in FireFox when it occurs. I assume it was after an update (one which did fix my viewable window to the full extent of my monitor). I used Adam's fix above...so far so good! I'll provide another update after a day or two once I verify the issue is gone.
