We cannot reproduce this issue at our end. Please have a look at this output.pdf (74.8 KB). Could you please share the sample code?

Stream document = GetDoc();

using (var fileConverter = new Converter(() => document))
                        {
                            var convertedDocumentStream = new ConvertedDocumentStream((converted) =>
                            {
                                converted.CopyTo(result);
                                converted.Dispose();
                            });
                             fileConverter.Convert(() => new MemoryStream(), convertedDocumentStream, GetPdfOptions());

This issue is reproduced at our end. If you load the source file (not as a stream), you will get the resultant PDF successfully. However, we’ve logged this issue in our internal issue tracking system with ticket ID CONVERSIONNET-4954. It’ll be now further investigated. You’ll be notified about the outcomes.
