This has got to be one of the most [censored word] bugs ever discovered in ZDoom code.

While analyzing the font's colors the font loader counted the number of pixels for each color used - and stored the result in a - BYTE ARRAY!.
Your font just hit the unlucky spot where the counter for the brightest color was a multiple of 256 - which made the loader consider it not present and mapped it to full translucency...

I've seen this in both 3.7.2 and master.

3.7.2, master or localization? 3.7.2 had a font offsetting problem, so this may be related.

I started noticing that a font I use in a mod gets partially cut off when it's colored. I have no idea why this happens. I'm pretty sure it used to work fine in the past.

Minimal sample here. Draws a text multiple times using all colors. You should see that they're all cut off at the top except for the untranslated color (which I padded a bit so it's easier to see).
