This bug affects me, too. I also find it happens most often (and maybe only!) when Libre Office and Firefox are both open. This happens on both of my computers. I would also like to confirm that when I press "Num Lock," the launcher hides properly, at least on the one machine I have access too right now. I will have to try Num Lock on the other one at home later to see if it works on that machine as well.
