However, now I took the time try disabling sub-pixel > rendering. It's probably due to anti-aliasing. Sub-pixel rendering is just one of the tricks that can be used when doing anti-aliasing.

Or just the anti-aliasing. What might be happening is that you're using a very light font (at the size you're using it, its lines are of thickness lower than 1 pixel, say), so without anti-aliasing it's "rounded up to 1", whereas anti-aliasing actually approximates the fractional pixel of thickness.
