I've bumped into a couple of issues with the box-shadow CSS property, one of which is definitely either a bug or an oversight, and one of which arguably is not:
1. Prince seems to rasterise box shadows, yet the --raster-dpi command line flag does not appear to apply to them. In fact, I can't seem to find any way to affect their resolution at all.
2. The way Prince is aligning rendered box shadows with the elements they're applied to produces a visible hairline at some zoom levels when there's high contrast between the background and the associated box, at least in every PDF viewer I've tried; minimal example attached.
