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.save();
    const currentCtx = this.ctx;
    
    
    
    
    
    
    
    
    
    
    
    
    
    if (!group.isolated) {
      info("TODO: Support non-isolated groups.");
    }
    
    
    if (group.knockout) {
      warn("Knockout groups not supported.");
    }
