Night Texture oddities when cycling render modes

I've no clue what's going on here. 8O

For some reason, when looking at objects with night textures available, I can see the night lights lit up in broad daylight, when using any render mode other than OpenGL 2.0. Sure, common around binaries, but this is with single stars. 8O

Graphics driver issue, perhaps? :|

I came to the default Earth in the default Sol system (w/ default Sol STC settings), and saw the same thing, albeit barely perceptible.

It happens on my system, too. Looks like a bug in Celestia to me.
