        notifyIcon = new NotifyIcon();
        MemoryStream memStream = new MemoryStream(iconTexture.EncodeToPNG());
        memStream.Seek(0, SeekOrigin.Begin);
        System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(memStream);
        notifyIcon.Icon = System.Drawing.Icon.FromHandle(bitmap.GetHicon());
