Problem viewing PDF format (1.5) in application in Edge

Good morning,   The last few weeks we received several complaints from our customers about a blurry pdf format that we show in our application. Yet nothing's wrong when we use it in an other webbro...

Hello PBoelens_23,

 

Thank you for taking the time to report this. I’m hoping to gather some more information to share with our engineers.

 

Is this a PDF on Share point opened in MS Edge or is the PDF opened directly in Edge?

 

Do you have an example PDF you're comfortable sharing with us?

 

Your version number and enabled feature flags. To gather this info, enter edge://version/?show-variations-cmd in the address bar. Take a screenshot of the visible page, don’t worry about capturing all the Active Variations. MS Edge has a built-in capture tool, to open it, click on the ellipsis(…) top right > Select Web capture.

      Thank you. If you don't mind, could you please post another image of your edge://version/?show-variations-cmd screen? The engineers are asking for your version number and enabled flags and the text in your image is too small for me to read. If you just capture everything above Active Variations that would be perfect. Again, thank you!

    We use a pdf plug-in (embedded pdf), I guess standard pdf in Edge. 

    Sadly I don't have an example ready, because it would contain customer information. 

    Microsoft Edge: 109.0.1518.78 (Official build) (64-bit) 

    Command-line: 

    "C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --no-startup-window /prefetch:5 --flag-switches-begin --disable-features=WebContentsForceDark --flag-switches-end

     

    Is this enough information or am I missing something?

    Kind regards, Patricia

      The PDF feature team is asking if disabling the PDF thumbnail cache will mitigate the issue. The steps on how to do this can be found below. Again, thank you for your help on this, and please let me know if you have any questions about the process.

       

      Page thumbnails can be disabled by using “—disable-features=”msPdfThumbnailCache” while opening Edge.

       

      1. Right click on the Edge shortcut icon.
      2. Click “Properties”.
      3. Go to “Shortcut” tab.
      4. In “Target” section, copy paste “—disable-features=”msPdfThumbnailCache”” at the end.
      5. Click “Apply”.
      6. Close the properties pop-up.
      7. Re-start Edge. (Make sure all the Edge processes have ended from the Task Manager.)

       

      OR

       

      1. Open command prompt. (Search “cmd” in Windows search box)
      2. Navigate to the directory where Edge is present. (run “cd C:\Program Files (x86)\Microsoft\Edge\Application” in cmd prompt.)
      3. Run “taskkill /im msedge.exe /f” to kill all the Edge processes running currently.

      Launch Edge using “msedge.exe –disable-features=”msPdfThumbnailCache”.

        Hi Jerimiah,

        Thanks for the reply. I wanted to test this above, but I had noticed that the problem is resolved already, even though my Edge version hasn't changed. Stil I tried it out but yeah, everything seems to work for now. Thanks again for the help!
