I have mentioned this several times during pre-beta with sample code and
renders so the POV-Team is aware of it.  

Should certainly be part of the bug list IMO.

But it seems like Nathan Kopp cannot replicate it, which is a problem since
it's him who should fix it.

Ok, i will post scene and renders again so everyone can try to replicate
it.

Thanks, I have included this bug report on the list.

At least I could reproduce it. Beta4, W2k sp2, 2*Celeron 400 on Abit
BP6, 512Mb memory.

Breakthrough!!!!  I figured out why I couldn't replicate your problem.  I
also figured out why adding an "invisible" object made the problem go away.

I have the following lines in my POVRAY.INI file:
Bounding=on
Bounding_Threshold=1

If I comment out the second line, I am able to replicate the problem.  These
settings determine if POV-Ray uses bounding slabs, which in turn affects the
use of light buffers and use of the vista buffer.

I still don't know the exact cause of the problem, but I'm getting much
closer now!

For now, the workaround is to add those two lines to your povray.ini file.

Hmm, interesting.  Isn't it normally that bounding causes problems and not
that they are solved by it?

I wonder what is the purpose for the bounding threshold? Why it couldn't
be just 1 and that's it? Is there any case where this would make rendering
considerably slower (and I'm not talking about 3 seconds vs. 1 second, but
for example 30 minutes vs. 10 minutes)?

That's good to hear.
The only problem is that the scene which showed me the bug the first time
contains some thousands objects, so I think bounding was used by default.
