Compatibility with gnome-shell 46

[EmileTrotignon]

gnome shell 46 was released recently and seems to breaks material-shell.

I use wayland.

Hopefully somebody will fix that. Gnome 46's Mutter will have explicit sync support and will work with Wayland on Nvidia, it's significant improvement. I had never created with any Gnome Shell extension however, so I'am probably not able to do it ...

Can confirm the @ajwild patch works.
