body: <p>I am using ngx-extended-pdf-viewer for my angular app and looks like multiple pdf pages are overlapping during viewing. here is my viewer code</p>
  <pre><code>&lt;ngx-extended-pdf-viewer
          *ngIf=&quot;isVisible&quot;
          [src]=&quot;pdfData&quot;
          useBrowserLocale=&quot;true&quot; 
          [textLayer]=&quot;true&quot; 
          [showPrintButton]=&quot;true&quot;
          [showDownloadButton]=&quot;true&quot; 
          [showOpenFileButton]=&quot;false&quot; 
          [showBookmarkButton]=&quot;false&quot; 
          [showPresentationModeButton]=&quot;false&quot; 
          height='90%'
          [zoom]=&quot;'100%'&quot;&gt;
  &lt;/ngx-extended-pdf-viewer&gt;
