I think this is mainly about this:
- mouse over systemloadviewer -> tooltip shows
- tooltip updates eg every 2 seconds -> we call setContent again and again
- sometimes it happens that the tooltip does not go away even when the mouse
  left the plasmoid

So sometimes the autohide does not work. I was able to reproduce this like 
this: I hvae two instances of the systemloadviewer side by side.
- hover over plasmoid1
- hover over plasmoid2
- now tooltip moves in an animation to plasmoid2. Now *during* this 
animation change the desktop (maybe now the plasmoid does not get a mouse 
leave event or such...). Now the tooltip will never go away, which is 
probably a bug :)
I cannot reproduce it always like this, but playing around with it finally 
reveales this behaviour. Maybe there are other ways to reproduce this.
