I’ve been searching for a solution to crisp edges in shapes and quite accidentally I discovered that PS miscalculates integer values.
If you display a grid (1×1 px) and turn on ‘snap to gid’, see what happens with, for example, a guideline.
If you drag it onto the screen under 16x zoom, it snaps perfectly to the pixel grid, falling dead on integer values:

but try moving it a few pixels right or left. The guideline gradually deviates from integer values and lands in between pixels
(whereas it should move with 1px ‘leaps’):

at some point reaches the middle of the way and finally snaps to an integer-value pixel perfectly again.
It takes a ‘cycle’ of several pixels until it is in integer values again. The same thing thus happens with shapes and so they are antialiased when, for example, resized.
To sum up, guidelines should adhere to the pixel grid and they do not. Despite 1x1px grid they land somewhere in between pixels and shapes aligned to them get fuzzy borders.
Shouldn’t it move pixel after pixel and align with the grid?
