Pixel grid snapping doesn't work

Hello,

[Please see attached video]
I need artwork to align to the pixel grid, but the auto alignment settings don't seem to be working with resizing the artwork (even when scaling up).

I have to manually adjust every point so it aligns properly with the pixel grid. This would be ok on non-straight segments, but even vertical or horizontal lines fail to align properly. Auto aligning with "Make pixel perfect" often distorts the artwork.

This happens with both newly created or pasted artwork.

CC is up to date.

The document was created with a web preset and pixel snapping options are turned on.

Snap to pixel is on (View menu).

Smart guides are turned off.

I need anti-alisasing on, since some segments aren't straight, but I want to retain the crispness on the straight lines.

Grid options:

Is there something else I'm overlooking? Or is this feature broken?

Thanks!
