Sometimes... sometimes there's this thing that happens when you move images in flash.
there's a bit of jitter, like it can't decide which pixel to snap to. So one might think to change the pixel snapping and smoothing. While there is a difference, that won't fix it.
Have a look at the tests. Use the gray box to scroll the images.
You should notice two things; the image on the left does the a weird jumpy thing when it slows down.
TESTYou might also notice that the image, while it doesn't do the jumping about, it is a bit softer.
That's because the right image has a scaleX = 1.001;
this distortion fixes the problem.
