Try other launcher, e.g. Doom Runner.

I see that lights in Untitled2 have bigger radius than in BadLights. Also shadow maps are probably turned off in BadLights.

IIRC these settings are for Doom, not for Heretic.

...but the transparent baddies don't seem to display that way.

Can you show a screenshot?

I don't know about Cinnamon but Plasma (KDE) "fixed" such bug several years ago.
You can also try to force compositing pipeline in Nvidia settings.
