I attribute that to a simple limitation of physics. Scaling a pixel to one pixel and a bit of another pixel is not physically possible, there is a hard physical unit[1]. They are some zoom ratios that will smooth well to the screen and some that won't. I think it's mostly noticed on text, the eye is incredibly good at noticing minimal variations. [1] Actually, font rendering on windows is already on a subpixel level. A pixel square is made of 3 rectangular colored sub pixels.
