If I remember correctly (from what one of the engineers told me at WWDC), sub-pixel antialiasing requires there be a known background behind the text. For a layer-backed view, you need to set the background to an opaque color and have the view draw the background. A CATextLayer is a little more complicated, but it's the same idea.
