Have you tried it wit rect.php?c=10000&s=3? Maybay it there to many rects out
of the frame, you can't see a difference. It is not the inital rendering, you
can see the difference only when click on rect 1, 2, 3 or 4.

I think that the dirtyRegion is calculatet correctly, but nothing cares about
it (at least in the Qt port)
