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

let pattern;
    if (IR[0] === "TilingPattern") {
      const color = IR[1];
      const baseTransform =
        this.baseTransform || this.ctx.mozCurrentTransform.slice();
      const canvasGraphicsFactory = {
        createCanvasGraphics: ctx => {
          return new CanvasGraphics(
            ctx,
            this.commonObjs,
            this.objs,
            this.canvasFactory
          );
        },
      };
      pattern = new TilingPattern(
        IR,
        color,
        this.ctx,
        canvasGraphicsFactory,
        baseTransform
      );
    } else {
      pattern = this._getPattern(IR[1], IR[2]);
    }
    return pattern;
  }
  setStrokeColorN() {
