I am having trouble making text fields look acceptable when using different typefaces.

See this screenshot taken from a test app I made to demonstrate the problem. It consists of a single XIB, with no code in the delegate or anywhere else. This is on OSX Mavericks with Xcode 5.1.1 but I haven't tried on other versions.

The default system font looks fine in the top text field, as you'd expect. Compare this to the one below: same exact size and shape, all I did differently was change the typeface in Interface Builder. Text is pushed downwards, and descending letters (lowercase pqjg) are clipped. The Menlo example below is also pushed downwards, though not quite as badly.

How do I fix this?
