I keep meaning to do this and forgetting... maybe a bug will help. https://github.com/libsdl-org/SDL/blob/main/docs/README-wayland.md#window-decorations-are-missing-or-the-decorations-look-strange >On some desktops (i.e. GNOME), Wayland applications use a library called libdecor to provide window decorations. If this library is not installed, the decorations will be missing. This library uses plugins to generate different decoration styles, and if a plugin to generate native-looking decorations is not installed (i.e. the GTK plugin), the decorations will not appear to be 'native'.
We can do this now libdecor is in tree.
