        <pre># Context
GNOS Project (<a href="https://gnos.in">https://gnos.in</a>) relies on LO thumbnails (generated by LO and
zipped at Thumbnails/thumbnail.png) to generate odt/odc/odp files previews.

# Description
Since version 6.3, thumbnails get a black background (instead of the white one
present in 6.2 and previous versions) rendering most file previews unusable.

# Steps to reproduce

- Install LO 6.3.2 on Ubuntu from ppa:libreoffice/ppa 
- Create any document, save
- Unzip
- Check Thumbnails/thumbnail.png with any image viewer

- Expected behaviour: the preview should have a white background
- Actual behaviour: the preview has a black background</pre>
