@Pablo Ok. I have a similar problem, that I reported in Bug #1072535
What mode do you have the launcher on? The other part of the problem I reported is that, in auto-hide mode, the launcher doesn't 'realise' the pointer is still on it, and it hides and reveals uncontrollably. Can you check if you have the same problem? Because I found those two issues often happened at the same time.
