Simple testcase
Seting custom titlebar throws an error when window size is smaller than CSD
decoration size - Gtk creates opaque surface with negative size then:
This simply sequence causes that:
gtk_window_resize(GTK_WINDOW(window), 1, 1);
gtk_widget_realize(window);
gdk_flush();
gtk_widget_unrealize(window);
gtk_window_set_titlebar(GTK_WINDOW(window), gtk_fixed_new());
gtk_widget_realize(window);
That affects Firefox when the main window has a minimal widget size and the
main window is configured before it's shown.</pre>
