Validation leads to Stage painting problem

Question

Original report by Andreas Liebelt (Bitbucket: aliebelt, GitHub: aliebelt).

As soon as a Validator validates a control and determined an erroneous value, the Stage transparency is gone and will never be restored:

#!java

import javafx.application.Application;
import javafx.scene.control.TextField;
import javafx.stage.Stage;

import org.controlsfx.dialog.Dialog;
import org.controlsfx.validation.ValidationSupport;
import org.controlsfx.validation.Validator;

public class ValidationStageDecorationErrorRunTest extends Application {


    public void start(Stage primaryStage) throws Exception {
        Dialog dialogWithoutValidation = new Dialog(primaryStage, "dialogWithoutValidation");
        dialogWithoutValidation.setContent(new TextField());
        dialogWithoutValidation.show();

        Dialog dialogWithValidation = new Dialog(primaryStage, "dialogWithValidation");
        TextField textField = new TextField();
        new ValidationSupport().registerValidator(textField, false, Validator.createEmptyValidator("message"));
        dialogWithValidation.setContent(textField);
        dialogWithValidation.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

The ValidationSupport works only when i change the input value? Because it's work for me only then.
