Java SE (Java Platform, Standard Edition)

Creating a custom cursor using png 32x32 images. The images are displaying perfect as a cursor on Windows and Mac but, on Linux the image is bad. Below I am pasting code to test the things by using some png image.

import java.awt.*;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.net.URL;

import javax.swing.*;

public class UserCursor {

	private void initComponents() {
		
		JFrame jf = new JFrame("Cursor Test");
		jf.setLayout(new BorderLayout());
		final JButton jb = new JButton("Change Cursor");
		jf.getContentPane().add(jb,BorderLayout.NORTH);
		jf.setSize(200, 200);
		jf.setVisible(true);
		final Cursor cur = createCursor();
		jb.addMouseListener(new MouseAdapter(){
			public void mouseEntered(MouseEvent arg0) {
				jb.setCursor(cur);
			}
		});
	}
	private Cursor createCursor() {
		Cursor userCursor=null;
		Toolkit toolkit = Toolkit.getDefaultToolkit();
		URL icon = getClass().getResource("images/someImage.png");
		Image image = new ImageIcon(icon).getImage();
		userCursor = toolkit.createCustomCursor(image, new Point(0, 0), "My Cursor");
		return userCursor;
	}
	public static void main(String args[])
	{
		UserCursor uc= new UserCursor();
		uc.initComponents();
	}

}
