The layers behind won't matter, because by that point you are in the compositor and far beyond Quartz.

Flicker won't let me download the silly thing so its harder to analyze, but the major difference between the first and third image looks like layout metrics (which is above Quartz) and so the question there might be what is Cocoa Text doing differently (which is beyond my knowledge). The first and second look like identical metrics with the issue I pointed out (sub-pixel on vs off).
