Thanks for your updates. I have today tried the new release and found that the issue was indeed fixed in the latest version if I used the default compliance option (PDF15).
However, when I used the other compliance option PDF1Ab, it produced an exception
System.NotImplementedException: The method or operation is not implemented.
var doc = new Presentation(@".\test.pptx");
var saveOptions = new PdfOptions();
saveOptions.Compliance = PdfCompliance.PdfA1b;
saveOptions.SaveMetafilesAsPng = false;
doc.Save(@".\out.pdf", SaveFormat.Pdf, saveOptions);
Note that if I use MS Office Powerpoint to save the PPTX to PDF using PDF/A compliant option, it can actually produce the result properly.

Could you help us check that? I’ve attached my test file for your reference.
