Pixel snapping not working anymore, snaps to decimal value

I am going crazy here. It seems in one of my files the snapping works not or in a weird way. Whenever I move elements vertically, they snap to a decimal value instead of to a clean value. they do increase by full pixels but the decimal parts stays.

All elements are clean and full pixels.

I have seen similar issues recently (very sensitive snapping, not… snappy snapping anymore). I suspect this happens when your try to align elements that are in the same section.
