I'm afraid I don't have an exact overlap-less example handy because the 
equivalent static font also hints a bit differently, hiding the issue. 
But I'm referring to the fact that the upper serifs cover the upper 
parts of the stems but the pixels above the stems are darker, so the 
overlapping area appears to be double-counted.
