I feel like this is something we need more contributors for, there’s only a handful of people working on Kirigami. Even less are interested in documentation - which is completely fair! An even smaller portion of that group has the time, energy and drive to test it on Windows unfortunately 
I personally would love a better Kirigami story on Windows (and macOS), but it’s unfortunate I don’t have much interest of supporting Windows (due to various roadblocks upstream and downstream), the time required and the fact that I don’t even use Windows often. I’m guessing lots of other developers share some of these problems…
