            Bug ID: 107376
           Summary: Displaying false preview when using pptx files.
           Product: LibreOffice
           Version: 5.3.2.2 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: philipp.petschner at celum.com

Description:
There are the same problems when using the Libreoffice program or Libreoffice
as command line. Libreoffice displays false previews in the sidebar on the
left. This is the same false preview as the command line conversion to pdf
does. For example: gradient from powerpoint is not shown, headers / logos are
not visible at all.

Steps to Reproduce:
1.open the pptx file and compare it to powerpoint (false preview is shown in
the left sidebar.
2.use libreoffice as command line and convert the pptx file to pdf

soffice.exe --headless --convert-to pdf originalFileRef

(or open the file with libreoffice and take a look at the previews in the left
sidebar)

Actual Results:  
false previews: headers are missing, gradients missing, ...

Expected Results:
same result as powerpoint shows. (The headers are actually shown in the big
view but not in the small preview)


Reproducible: Always

User Profile Reset: No

Additional Info:
I would be happy to send you some example files. And show you the problem in
detail.
