+Subject: Ensure that QMenu is polished before setting the screen in popup()
+
+Some styles alter the widget that will influence the underlying platform
+window. An example is when a style would want to draw the menu with some
+transparency and sets the Qt::WA_TranslucentBackground attribute. This
+needs to happen before the platform window is created. However calling
+QWidgetPrivate::setScreen will end up creating the window and the
+surface format will be fixed at this point.
