            Bug ID: 114705
           Summary: Images distorted after export to PDF from Writer with
                    enabled JPG-compression if OpenGL ist active
           Product: LibreOffice
           Version: 5.4.4.2 release
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Printing and PDF export
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
If I export a writer document with embedded images to a pdf, some of them get
distorted using the standard-export-settings. If I deactivate the
jpg-compression inside the export dialog, the images get not distorted. The
same happens if I let the jpg-compression activated but deactivate OpenGL. The
bug was adressed in further versions and was announced to be fixed
(https://www.bitblokes.de/libreoffice-5-1-rc1-ist-verfuegbar-kuemmert-sich-um-schusterjungen-und-hurenkinder/,
" Weiterhin sollen Bilder bei einem PDF-Export nicht mehr verzerrt werden, wenn
OpenGL aktiviert ist"), but it seems like it still exists in 5.3.7 and 5.4.4.

Steps to Reproduce:
1. Create a writer document with embedded images
2. Export to pdf with standard settings
3. Export to pdf with deactivated OpenGL or without jpeg-compresion

Actual Results:  
It seems like not all images get distorted, at the moment I don't know why some
are and some not. But I seems that bigger images are affected.

Expected Results:
Images should be not distorted


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes
