I've seen this happen as well. I think it happens both on Windows and  
Ubuntu - but certainly on Ubuntu. The issue seems to appear when you  
change a layer's visibility in the layer list while the map is still being  
rendered. QGIS ignores the change you do while the map is rendering and  
thus the user can end up with layers which are deactivated in the layer  
list, but still drawn in the map. To fix it, the user has to enable and  
disable the layer again.

If someone can confirm this in master, we should open a ticket.

Best wishes,
Anita
