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

if (!this.contentVisible) {
      return;
    }
    this.groupLevel--;
    const groupCtx = this.ctx;
    this.ctx = this.groupStack.pop();
    
    
    this.ctx.imageSmoothingEnabled = false;
    if (group.smask) {
      this.tempSMask = this.smaskStack.pop();
    } else {
      this.ctx.drawImage(groupCtx.canvas, 0, 0);
    }
    this.restore();
  }
  beginAnnotations() {
