There are issues with the light UI, whatever method used to achieve it.

Most annoying; the toolbars won't be drawn correctly when floating.

And some minor quirks like dialogues not rendering as they should (for instance; the colour editor)

But having used Xara Studio from it's first Windows incarnation (1994) I still prefer the Classic interface.

I'd love to have this light gray UI given an overhaul to bring it to the modern and clean UWP interface. I tried to hack the Xara UI an update by using Resource Hacker to binary edit the xaradark.cjstyles file but that's to much of an hassle.

Good examples? FireAlpaca, MS Paint3D come close.
