When I am trying to load this pdf http://merlin_test.s3.amazonaws.com/myPdf.pdf, it's unable to render all the contents. There is a blue background which is not visible and some of the texts are not visible as well as the color is not proper. Can someone please help

transferMapGreen = transferMaps[0];
        transferMapBlue = transferMaps[0];
        transferMapGray = transferMaps[0];
        break;
      case 4:
        transferMapRed = transferMaps[0];
        transferMapGreen = transferMaps[1];
        transferMapBlue = transferMaps[2];
        transferMapGray = transferMaps[3];
        break;
    }
  }

        [white, black] = [black, white];
