I have some news: I'm actually running Ubuntu inside a VirtualBox VM and my problem was caused by the mouse integration. If you have mouse integration enabled, as soon as you reach the display border the mouse leaves the VM. Therefore the launcher won't show up again. Therefore I don't think it is an Unity bug (maybe not even a bug at all).
