As I said, I just come by from time to time to check the changelogs to see if it's been fixed. (Or, even better, colour distribution options given) So far, no mention.
However, you say "your glitch". Does that mean that you're not getting near-100% dark-skinned guys? That when you screw the guy(s?) from the first institute quest, the animation shows white guy(s?)?
As I said, been a while.
Tried the latest stable build (0.3.3.04), new game, to the pub. After almost 2 full shifts, I got about 10 scenes. One guy was white, one a lightish brown, and the rest black.
Unless it's bad RNG, no, this is not fixed. I'm not even going to bother going for the investigator or the janitor or what-have-you, as I'm just going to assume they'll also use the bad NPC generator.
