--- Comment #3 from Buovjaga <ilmari.lauhakangas at libreoffice.org> ---
The chart is in fact a PDF image. You can see this by doing right-click - edit
with external tool. It opens as .tmp.pdf.

I bibisected with win32-5.4 and got this range:
https://gerrit.libreoffice.org/plugins/gitiles/core/+log/ff8b873936aa72b17309da4bfc2775573a5b1f55..169bd7718264b0e312052757f9bbd2321e1399c2

Looking at the range actually got me to try and figure out the type of the
image. It has many commits about "PDF export of PDF image" by Miklos. Bug
107018 bug 107013 and bug 107089 are referenced.
