I'm not exactly sure what you mean by "this". We don't offer a supported
way to turn off subpixel AA (on any platform) and I'm not aware of any
clamor for it. I don't know why that is; maybe Web designers have bigger
complaints about our rendering, or maybe our support for subpixel
positioning and always-on text shaping mitigates the problem.
