And it's always amazingly convenient and user-friendly when a MacOS application freezes and you can't move its windows or interact with it at all. Especially when it's fullscreen. At some point perfection in one area impedes functionality in another and I think having one frame lag between window frame and window contents is an acceptable price to pay for having always accessible window controls. I know I'll never use GNOME and I'll live happy, but the issue is that their stubbornness starts leaking GNOME implementation details to everyone else. They are not acting like good community contributors.
