Yeah, that seems to be because I use sublime text for rendering. Sublimes Syntax coloring was updated recently, so the code is now interpreted and colored differently.

When adding a new font, I like to only render the new one because of the sheer number of screenshots, files and time it takes to redo everything. Currently the site contains 2569 individual images. But I'll look into it later today. Maybe I can fix it. It's distracting right now. Good eye for noticing though :D
