'LWJGL2 bugged cursor

I've been trying to make custom cursor in LWJGL2 but it's bugged. (Also I know LWJGL2 is unsupported)

I won't lie, I found this code..

The code:

public static void loadCursor(String path) {
    try{
        File f = new File(path);
        if(!f.exists()) return;

        BufferedImage img = ImageIO.read(f);

        final int w = img.getWidth();
        final int h = img.getHeight();

        int rgbData[] = new int[w * h];

        for (int i = 0; i < rgbData.length; i++)
        {
            int x = i % w;
            int y = h - 1 - i / w; // this will also flip the image vertically

            rgbData[i] = img.getRGB(x, y);
        }

        IntBuffer buffer = BufferUtils.createIntBuffer(w * h);
        buffer.put(rgbData);
        buffer.rewind();

        Cursor cursor = new Cursor(w, h, w / 2, h / 2, 1, buffer, null);
        Mouse.setNativeCursor(cursor);

    } catch (Exception e){
        e.printStackTrace();
    }
}

The problem is that some cursors are buggy
