Does this happen on a retina screen?

I can confirm on rMBP, so yes.

This is what we're discussing in  Issue 593835 . I was thinking about it more - perhaps it's not related to NSVisualEffectView, but maybe instead some special styling we're applying to the text.

I don't think that's it, the issue is still there when I removed the shadows
