            Bug ID: 138152
           Summary: Images are blurry when a pptx (or odp) is imported
                    from Office Online
           Product: LibreOffice
           Version: 7.1.0.0.alpha0+ Master
          Hardware: All
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Impress
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: vfrico at gmail.com

Description:
LibreOffice Impress show some blurry images when a file exported from Office
Online is opened in local machine

Steps to Reproduce:
1. Download attached file (happens with .pptx and .odp)
2. Open it with LibreOffice (7.1 alpha - nightly built appimage)
3. Go to 4th slide
4. Check if images are blurry https://imgur.com/a/4d4R3RQ

Actual Results:
Some of the images over the figures are shown as blurry images.

Open the presentation mode and images are shown clear

Expected Results:
Images should appear clear and without artifacts


Reproducible: Always


User Profile Reset: No



Additional Info:
Images shown are very blurry and is almost impossible to see what are them. The
file has not been generated with LibreOffice, it was generated using PowerPoint
online and then downloaded in my local machine. It happens to .pptx and .odp.

I'd like to clarify that it is not [or it should not be] an export error of the
online platform, because it disappears on presentation view: images are shown
clearly, but only on the big screen, on the presenter view, they are still
blurry.

Footnote: after having the program opened some minutes (between 5 and 10
minutes), the images are then shown clear.
