Ok, happens also with latest head. I will have to search when it
started, not fun as I did not play with media.

maybe color models are to be suspected as so many  relatively recent changes
happened ?
(rgb > srgb rgbf rgbt RAL...)

Works ok in (qtpovray)3.8, using #version 3.6 and #version 3.8

Line 786 has a negative light source, so maybe scroll down to that section and
start commenting out some lights and see what happens.

after that is // submarine and media

light in lines Line 73 & 74 has media_interaction off

Other than that - no idea.

Negative light are honored, not the problem.

Commenting the media in the last union, get the same bad result as
hgpovray38 with povray master 3.8;

Ok, I can fix it... but I do not understand yet why it happened and how
it works.

I'd not have looked if not for the claim of the same bad results in 
povray master 3.8, but I branched off the last commit to master and I do 
not see that line in tracepixel.cpp commented. (I've not run the test case)

If any help, I went on to look at the state of tracepixel.cpp for every 
commit since the move the github. I see twelve up to v3.8 master head 
and none have the precompute... line commented.

Thanks ! It does render with blue background now.
Next issue is when I try to render the grenadine scene, I get a "Parse Error:
Cannot open include file lemon.inc." (disregarding any +L option).
That however could also happen with standard povray 3.8.
