I have fixed it on Linux:
https://github.com/openjdk/jfx/pull/77
Can be ported to the current code:
void WindowContext::set_maximized(bool maximize) {
is_maximized = maximize;
if (maximize) {
// enable the functionality
GdkWMFunction wmf = (GdkWMFunction)(gdk_windowManagerFunctions |
GDK_FUNC_MAXIMIZE);
gdk_window_set_functions(gdk_window, wmf);
gtk_window_maximize(GTK_WINDOW(gtk_widget));
} else {
gtk_window_unmaximize(GTK_WINDOW(gtk_widget));
}
}

Hi Kevin,
Sounds logical.
I will file an issue in the JBS.
Best regards,

Subject: Re: Maximized undecorated stage
Ideally, we wouldn't have this sort of platform-specific behavior. I can
see why the underlying platform might not support the concept of
maximizing an undecorated stage, so we either need to disable it on
Windows, live with the behavior, or else find some solution on macOS and
Linux.
