GIF stops animating while gaming mouse is moving

While I move my gaming mouse inside a javax.swing.JFrame, all animated GIFs (javax.swing.ImageIcon inside a javax.swing.JLabel) stops animating until the mouse stops moving.

This only happens with a gaming mouse with a driver on macOS (tested it with a Rocket-Kone XTD and a Razer gaming mouse on two computers). When I use other mice everything works fine.

The gaming mice also causing javax.swing.Timers to stop calling their actionPerformed() methods. I opened a thread here for this problem, but this can be solved using java.util.TimerTask instead. (Edit: Actually TimerTask also don't fix it because the JFrame doesn't repaint until the mouse stops moving.)

But I found no alternative for animating GIFs. I'm more interested to solve the problem instead of using alternatives though I would be thankful for an working alternative too.

Code:

import java.lang.reflect.InvocationTargetException;

import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.SwingUtilities;

public class Mouse {
    public static void main(String[] args) {
        try {
            SwingUtilities.invokeAndWait(new Runnable() {
                public void run() {
                    new Mouse();
                }

            });
        } catch (InvocationTargetException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

    public Mouse() {
        JFrame frame = new JFrame();
        JLabel label = new JLabel(new ImageIcon(getClass().getResource("waiting.gif")));

        frame.setSize(500, 500);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);

        frame.add(label);
    }
}

Solution

  • I solved the problem as I reduced the polling-rate of my mouse from 1000Hz to 500Hz. Now everything works perfect. I think the problem was that the UI-Thread was overextended handling the 1000 polls per second so it was to busy to animate the GIF.
