Although it could probably be considered a 'bug', it's not worth bothering the
POV-Ray team with.  I'm pretty sure that they know about it, and there's not
much they can easily do about it because of the way POV's radiosity works,
since the 'radiosity buffer' is generated on-the-fly as the image is rendered.
Probably providing some overlap of pixels when rendering partial images could
make the dividing line less visible.
