Not repaint panel when scene moved

Question

hi, i have next components. JPanel, which contains JScrollPane with JLabel on it. Right now, when mouse moves over JPanel, all of those components (or at least JLabel) are repainted.
How i can forbid repaint method on mouse moved event?

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Repaint extends MouseMotionAdapter
    JLabel report = new JLabel(" ", JLabel.CENTER);
    public static void main(String[] args)
        Repaint test = new Repaint();
        TalkingLabel label = new TalkingLabel("label");
        label.addMouseMotionListener(test);
        JFrame f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.getContentPane().add(new JScrollPane(label));
        f.getContentPane().add(test.report, "South");
        f.setSize(400,400);
        f.setLocation(200,200);
        f.setVisible(true);
    public void mouseMoved(MouseEvent e)
        // did you do something here to cause repainting?
        report.setText("x = " + e.getX() + "  y = " + e.getY());
class TalkingLabel extends JLabel
    public TalkingLabel(String text)
        super(text, CENTER);
        setFont(getFont().deriveFont(18f));
        setBackground(Color.pink);
    protected void paintComponent(Graphics g)
        ((Graphics2D)g).setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                                         RenderingHints.VALUE_ANTIALIAS_ON);
        super.paintComponent(g);
        System.out.println("talking label is repainting itself");
}
