Drop-shadow in an undecorated Pane

Question

I\'m trying to make my Pane a little bit better, visually, so, what I\'m doing is: set my stage UNDECORATED (OK) and (TRYING) to add a drop-shadow effect (NOT OK).

Simple working example.

Here is fxml structure:

AnchorPane(200,200) // pane for space for shadow
    \- AnchorPane(center) // appliction pane
         \- Label // application content

Real screen.fxml:

Main.java

@Override
public void start(Stage stage) throws Exception {
    FXMLLoader loader = new FXMLLoader(getClass().getResource("/sample/screen.fxml"));
    AnchorPane shadowPane = loader.load();
    AnchorPane rootPane = (AnchorPane) shadowPane.lookup("#rootPane");
    rootPane.setStyle("-fx-effect: dropshadow(gaussian, rgba(0, 0, 0, 0.4), 10, 0.5, 0.0, 0.0);" +
                      "-fx-background-color: white;"); // Shadow effect

    Scene scene = new Scene(shadowPane);
    stage.setScene(scene);

    shadowPane.setBorder(new Border(new BorderStroke(Color.RED, BorderStrokeStyle.SOLID, null, null))); // Some borders for for clarity

    shadowPane.setStyle("-fx-background-color: transparent;"); // Makes shadowPane transparent
    scene.setFill(Color.TRANSPARENT); // Fill our scene with nothing
    stage.initStyle(StageStyle.TRANSPARENT); // Important one!
    stage.show();
}
