Image is not generated properly

generating a very large image 54k x 9k size, setting the background of the image to be white, but only 60% of the image is background color white, the other part is transparent, here’s the sample code:

License oLic = new License();

    Bitmap oImage = new Bitmap(54897, 9500, System.Drawing.Imaging.PixelFormat.Gdi);
    Graphics g = Graphics.FromImage(oImage);
    g.SmoothingMode = SmoothingMode.HighQuality;
