I remember having that with the fixed pipeline.
Set the fog color to the same color your background is.

Turns out the frustum was set further back than the fog, so pixels were being drawn further than gl_Fog.end, so fog was negative. Setting the fog end equal to the far plane fixed it.

I like the DARK layout!

you could use a max(0.0, fog) to avoid that if.

By the way, is it necessary to bind the alpha map, or is there a way to use it without burning a texture unit (or does that even matter with shaders)?

I like the DARK layout!
