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

ctx.fillText(character, x, y);
      }
      if (
        fillStrokeMode === TextRenderingMode.STROKE ||
        fillStrokeMode === TextRenderingMode.FILL_STROKE
      ) {
        if (resetLineWidthToOne) {
          ctx.save();
          ctx.moveTo(x, y);
          ctx.resetTransform();
          ctx.lineWidth = Math.round(this._combinedScaleFactor);
          ctx.strokeText(character, 0, 0);
          ctx.restore();
        } else {
          ctx.strokeText(character, x, y);
        }
      }
    }
    if (isAddToPathSet) {
      const paths = this.pendingTextPaths || (this.pendingTextPaths = []);
      paths.push({
        transform: ctx.mozCurrentTransform,
        x,
        y,
        fontSize,
        addToPath,
      });
    }
  }
