Displaying a JTextField in fullscreen exclusive mode without flickering

I have been stuck on this now for almost a week, the problem is that the textfield keeps flickering. I have read that swing does not work well with fullscreen exclusive mode, but I'm not sure what else to do other than create my own class similar to a textfield and detect every single key press which doesn't seem the right thing to do. I have created a cut down version of the problem and have pasted below, any help would be appreciated :)

- If this line is uncommented "TextFieldTest.this.tfChatField.paint(g);" then it will display the textfield at the top of the screen, and a flickering textfield at the bottom(which is where it's meant to be)

Java Code:

package textfieldtest;

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.DisplayMode;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.GraphicsConfiguration;
import java.awt.GraphicsDevice;
import java.awt.GraphicsEnvironment;
import java.awt.image.BufferStrategy;
import java.lang.reflect.InvocationTargetException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.SwingUtilities;

public class TextFieldTest implements Runnable {
    
    private JFrame frame;
    private BufferStrategy bufferStrategy;
    private JTextField tfChatField;

    public TextFieldTest(){
        frame = new JFrame();
        tfChatField = new JTextField("Type here to chat");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setLayout(new BorderLayout());
        frame.add(tfChatField, BorderLayout.SOUTH);
        frame.setVisible(true);
        frame.createBufferStrategy(2);
        DisplayMode dm = new DisplayMode(640,480,32,60);
        GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
        GraphicsDevice gd = ge.getDefaultScreenDevice();
        GraphicsConfiguration gc = gd.getDefaultConfiguration();
        gd.setFullScreenWindow(frame);
        gd.setDisplayMode(dm);
        bufferStrategy = frame.getBufferStrategy();
    }
    public static void main(String[] args) {
        TextFieldTest test = new TextFieldTest();
        new Thread(test).start();
    }
    
    public void render(final Graphics g){
        g.setColor(Color.black);
        g.fillRect(0, 0, 640, 480);
        try {
            SwingUtilities.invokeAndWait(new Runnable() {
                    @Override
                    public void run() {
                        //TextFieldTest.this.tfChatField.paint(g);
                    }
            });
        } catch (InterruptedException ex) {
            Logger.getLogger(TextFieldTest.class.getName()).log(Level.SEVERE, null, ex);
        } catch (InvocationTargetException ex) {
            Logger.getLogger(TextFieldTest.class.getName()).log(Level.SEVERE, null, ex);
        }
        g.dispose();
        bufferStrategy.show();
    }

    @Override
    public void run() {
        while(true){
            Graphics g = bufferStrategy.getDrawGraphics();
            render(g);
            try {
                Thread.sleep(10);
            } catch (InterruptedException ex) {
                ex.printStackTrace();
            }
        }
    }
}
