Thanks for reporting.

The attached images shows that this is an issue with the Embed viewer. In the 
image it is actually Chromes built in viewer displaying the pdf in an iframe.

I will look into options for fixing this
- Fix the z-image for the iframe. This is not so easy, since external plugins 
not always respect z-index.
- Detect/catch that a dialog is opened, if so hide the iframe (adding an 
optiona button to open again).

Thanks for your comments. Why are you saying it's Embed viewer? In my  
tomcat/shared/classes/alfresco/site-webscripts/org/alfresco/components/preview/w
eb-preview.get.config.xml I set: 

<plugin-conditions>
      <condition mimeType="application/pdf">
         <plugin>PdfJs</plugin>
         <plugin>Embed</plugin>
      </condition>

      <!--
          Enables the PdfJs viewer for other content which can be transformed to PDF or Embed in older browsers.
      -->

      <condition thumbnail="pdf">
         <plugin src="pdf">PdfJs</plugin>
         <plugin src="pdf">Embed</plugin>
      </condition>

How can I distinguish wich plugin it's using? From log file?

I'm saying this beacuse the PdfJs viewer does not look like the chrome built in 
viewer, and that is what's in your screenshot.

What may have happened for you (so that the Embed viewer is used)
- The PdfJs viewer failed for some reason. The viewer mechanism test each 
viewer in order to find one that can display the content. So it first tested 
the PdfJs viwer, it failed, but then the Embed viewer worked. Why I can't tell.
- Or, you have double config files somewhere in your class path.

The issue is now resolved by

The iframe with the plugin is hidden as soon as a dialog is or menu is opened.
