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

const { context: ctx } = this.cachedCanvases.getCanvas(
      "isFontSubpixelAAEnabled",
      10,
      10
    );
    ctx.scale(1.5, 1);
    ctx.fillText("I", 0, 10);
    const data = ctx.getImageData(0, 0, 10, 10).data;
    let enabled = false;
    for (let i = 3; i < data.length; i += 4) {
      if (data[i] > 0 && data[i] < 255) {
        enabled = true;
        break;
      }
    }
    return shadow(this, "isFontSubpixelAAEnabled", enabled);
  }
  showText(glyphs) {
