Created attachment 99394

some screenshots showing the problem

I rendered the same cube two times, first culling the front faces, then culling
the back faces. The backside has a red light, so that backside pixels are draw
red. Since the front side is painted, no red pixels should ever be seen. As you
can see on the screenshots, there are red pixels on the edges, depending on the
angle.
