#3 radius-controlle bug in 0.4

When I switch to radius-controlle, after having rendered as Bestes bild, the image is very weird, parts dont seem to be rendered at all. I see columns of repetitions. It is just noise to me.

Switching to Keines wiederholung after that, produces a picture even more weird, black and noisy.

Switching to bestes bild again, produces a correct image again.
