Steps to reproduce:

1.Open gnome-mahjongg.
2.Maximize the window.
3.Close the application.
4.Re-open the application.

WSL logs:

No response

WSL dumps:

No response

Expected behavior:

The issue does not occur if the app starts in windowed mode and is maximized manually afterwards. It also doesn't occur using GDK_BACKEND=x11 gnome-mahjongg

Actual behavior:

The application crashes immediately on startup if the previous state was "maximized" while running on a Wayland session over RDP (Weston/Mutter-RDP).
Gdk-Message: Error 71 (Protocol error) dispatching to Wayland display.

The WAYLAND_DEBUG=1 log shows a mismatch between the buffer sent by the client and the state expected by the compositor:
wl_display@1.error(xdg_wm_base@18, 4, "xdg_surface buffer (900 x 600) does not match the configured maximized state (0 x 0)")

GTK 3 fails to correctly negotiate the initial geometry during the xdg_toplevel.configure sequence on RDP-based Wayland compositors when the window state is set to maximized.

I confirmed that editing the state stored in the binary database ~/.config/dconf/user with dconf-editor allowed the application to start again, in windowed mode.
