Qt.WindowMaximized does not work on Ubuntu 24.04 Gnome&Wayland

see https://bugreports.qt.io/browse/PYSIDE-2706

Gist:

• Without setWindowState: the app starts in ~1sec
• with setWindowState(Qt.WindowMaximized): the app appears in the docker and "ps" tells me it exists: but the app never renders, I cannot make it appear. Nothing else happens, no error message, no nothing.
• setWindowState(Qt.WindowMinimized): the app works as expected: it is minimized and can be maximized. It appears in docker.

I don't know how to write a C++ example but the case is so simple that anybody who has written C++ and QT before, can do it in a minute.
