Sorry, you are totally right, you can save recalculating the screen polygon there. So this really should be done instead.

Now QPainter paints the stroke of such Polygons by connecting each point, leading to unwanted connections between the outer boundary and the inner holes. See http://i.imgur.com/25rjs.png (from Ander).
