Huge Memory Consumption for Transparent Stage

Question

When executing the test below the memory consumption in the Task Manager grows up to 2GB within seconds on my test system - the issue does not occur when the stage style is changed from TRANSPARENT to UNDECORATED. Tested on Win7, 8GB with FX8b116.
public class TransparentStageMemoryIssueTest extends Application
  public static void main(String[] args)
    Application.launch(args);
  @Override
  public void start(Stage stage)
    System.err.println(System.getProperty("javafx.runtime.version"));
    //stage.initStyle(StageStyle.UNDECORATED);
    stage.initStyle(StageStyle.TRANSPARENT);
    final BorderPane root = new BorderPane();
    root.setStyle("-fx-background-color:#808080;-fx-background-radius:30;-fx-border-radius:30;-fx-border-width:14;-fx-border-color:blue;");
    Scene scene = new Scene(root, 800, 600);
    stage.setScene(scene);
    stage.setX(10);
    stage.setY(10);
    stage.show();
    new Thread()
      public void run()
        for (int i = 0; i < 1000; i++)
          Platform.runLater(new Runnable()
            @Override
            public void run()
              int minSize = 500;
              int maxSize = 1000;
              int w = minSize + new Random().nextInt(maxSize - minSize);
              int h = minSize + new Random().nextInt(maxSize - minSize);
              Window win = root.getScene().getWindow();
              win.setWidth(w);
              win.setHeight(h);
          try
            sleep(50);
          catch (InterruptedException e)
            e.printStackTrace();
    }.start();
