wonder if DropShadow could be implemented via Adorners https://github.com/Microsoft/xaml-standard/issues/101 (don't think implementing it via Borders is an option, since borders don't render over the adjacent controls)

I think in Silverlight you had to turn off shadows for hardware acceleration to kick in. Using shadows resulted in too much redrawing too (would invalidate other controls). Probably most controls aren't doing caching of their graphics (backbuffering) themselves. Not sure what the rendering system does in that aspect and if UWP's Compositing does such things.
