Ugly linux font while viewing source code (BB-6401)

While viewing source code the fonts are ugly:

As a matter of fact this message I'm typing looks just ugly as the fonts in the screenshot.

Contrary, when I'm viewing source code diffs the fonts look awesome.

Please fix it The new interface is so beautiful, so the contrast with the ugly fonts is killing me!

Thanks!
