Screenshot from neverputt without lightning (There should be very light colors)

Sepcial light sources aren't calculated when rendering. This causes some opengl applications to have very dark colors.

List of application that I know are broken:
Neverputt
Foobillard
Billard-GL

I found out that also diffuse lightning in compiz is broken. I guess all other cases are also using diffuse lightning which seems broken.
Comment 2 Pauli 2009-06-20 17:29:19 UTC 
I tested now same system with KMS disabled and lightning works fine.

I alo had look at neverputt code and it looks very simple lightning with only one source without any extra parameters. It seems like ithould work ame way as glxgears but something not working correctly. In other words I couldn't produce minimal test case to find out what is causing the problem.

This had been fixed in the master in the lastest 12 days so I mark it fixed.

Mass version move, cvs -> git
