Titan, as seen with OpenGL 2.0 rendering path

Celestia 1.5.1, with r300g from git, RV350 card.

When viewing Saturn's moon Titan with atmospheres enabled (Ctrl-A), the atmosphere appears orange for basic, multitexture and OpenGL vertex program rendering paths, but blue for OpenGL 2.0 rendering path. (Cycle through available rendering paths using Ctrl-V.)

This inconsistency is suspicious - I suspect a bug.

And Basic, Multitexture rendering paths, too.

Same issue with llvmpipe so it's probably a gallium bug, not specific to r300g.
Comment 3 Chris Rankin 2010-12-12 10:23:05 UTC 
This also happens with NVIDIA's binary blob and the OpenGL 2.0 path, although not with the "OpenGL vertex program/NVIDIA combiners" path. So if this is a bug, I am assuming it is in Celestia instead.

I also get this on Radeon HD 4350, driver 6.13.2, Xorg 1.7.7, Mesa 7.9 R600c, kernel 2.6.36. See Bug 30502.
Comment 5 aceman 2011-05-02 12:22:26 UTC 
I see it also with celestia 1.6.1 and software rendering in Mesa 7.10.2.
