Description Stefano Teso 2011-04-23 04:48:10 UTC 
Water in sauerbraten misrenders (it's painted black) when enabling both (a) water reflections, and (b) 'high quality' shaders. Lowering the shader setting or disabling shaders altogether solves the problem.

I'm running debian amd64 unstable, with custom kernel 2.6.39-rc4+ (git 91e8549), on a:

01:00.0 VGA compatible controller [0300]: ATI Technologies Inc Robson CE [AMD Radeon HD 6300 Series] [1002:68e4]

Mesa is from git as well, here's what glxinfo has to say about it:

OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD CEDAR
OpenGL version string: 2.1 Mesa 7.11-devel (git-a22aba4)
OpenGL shading language version string: 1.20

Screenshots to follow.

The map "river_c" seems to be a good testcase for this. 

Water is rendering correctly with shaders on "high quality" with llvmpipe.

This seems to be fixed with current git master, can you confirm?
