Recent update caused all function/class definition text to appear black, regardless of theme.

After the most recent Pycharm update all my function and class definitions are showing as black text, regardless of the theme I use. If I look in Editor > Colors & Fonts > Language Defaults, the example looks correct (which is a neon green for my normal theme), but in the actual editor it's black and won't change. This is obviously a bit of a pill, as I use a dark theme.

I've attached a screenshot.

Does anyone know what's going on here?

EDIT: screenshot doesn't seem to be showing, so here's an imgur link: http://i.imgur.com/Jtdgdw6.png
