How to make Emacs 24 render font like Sublime Text 2?

Question

The following graph shows a comparison between Sublime Text 2 (left) and Emacs 24 (right, installed from homebrew) on how they render texts on my Mac. They all use Monaco with normal weight, but as you can see, Emacs renders text in a somewhat aliased way. The problem didn't show up when I was using Emacs 23 on my Mac. I'm wondering if there is any way to fix it.

Answer 1

I fix the problem by using compiled Emacs For Mac OS X instead, and it renders texts well. The Emacs version I mentioned in the question was built from git repository, I guess that was the problem since it was too cutting edge.

Update:

The bug seems to be introduced in the latest Emacs build, see report #11484 #12996 #13106.
