vlcj EmbeddedMediaPlayerComponent未调整为原始大小

Question

请查看附件中的图片。在最大化后将窗口调整为原始尺寸时，vlcj媒体组件会隐藏控制按钮。

public class PlayerVLCPanel extends JPanel {
    private EmbeddedMediaPlayerComponent playerComponent;

    public PlayerVLCPanel() {
        this.playerComponent = ComponentStore.getCameraStreamer();

        setLayout(new BorderLayout());
        add(this.playerComponent.getVideoSurface(), BorderLayout.CENTER);
    }
}

public class CameraJobControlPanel extends JPanel {
public CameraJobControlPanel() {
DesignGridLayout layout = new DesignGridLayout(this);

    layout.row().grid(expertDnLabel).add(expertDnField);
    layout.row().right().add(startCamButton, stopCamButton, startLazerButton, stopLazerButton).fill();
}
}

public class MainPlayerContainer extends JPanel {
public MainPlayerContainer() {
    setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
    setBorder(new EmptyBorder(3, 3, 3, 3));

    add(topRegion()); // contains PlayerVLCPanel
    add(bottomRegion()); // contains the Control buttons    
}
}

最后，

JFrame frame = new JFrame("vlcj Testing");
frame.add(new MainPlayerContainer());

frame.setLocation(100, 100);
frame.setSize(1050, 600);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);

如何防止此行为？提前谢谢。
