PDF where the white background is visible

SUMMARY
When I want to get an overview of a lot of PDF files, I open one in Gwenview and navigate / delete using the keyboard.
However, the thumbnails of PDFs contain no white background.

The background and a drop shadow are shown if the PDF contains a white background shape, as confirmed by opening the PDF in LibreOffice Draw.


STEPS TO REPRODUCE
1. Open a PDF in Gwenview
2. Enable thumbnails

OBSERVED RESULT
The thumbnail has no white background, instead the gray background of the widget is visible.

EXPECTED RESULT
I expect the thumbnail to look like in Okular.
