Please see the attached document (sample-broken.doc)
Converting this document to PDF using Aspose Words v14.12.0 leads to a PDF with the top right content partially missing (see sample-broken-converted.pdf).
If you drag and move the top right area of the word document (sample-fixed.doc) and then convert the area renders correctly (sample-fixed-converted).
Unfortunately we have many historic documents we cannot alter manually so the drag and drop solution is not realistic, we need the conversion to work correctly if possible.
During our attempts to debug this we also saw the same rendering issue converting the broken word doc to XPS.
