Drawer OverlayBackground Corner Radius

[Jason37174]

How do I set the corner radius of the overlaybackground of a drawer? My main window has rounded corners and whenever I open the drawer the overlay is visible outside the main window.

See sample image for details. I'm assuming it can be done with some sort of style I can apply to the drawerhost but I'm struggling to figure it out. The drawer itself, has a corner radius so that looks fine, but not the overlay layer.

Thanks for any help!

Can you try setting ClipToBounds=True on the DrawerHost and/or Window level and see if that makes a difference?

If possible, can you share your custom window chrome setup so we can test with it?
