please also provide the code snippet you used for conversion

// load PDF with an instance of Document
var document = new Document(inputfilepath);

// Save document in word format
Aspose.Pdf.DocSaveOptions docoptions = new Aspose.Pdf.DocSaveOptions();
docoptions.Format = DocSaveOptions.DocFormat.DocX;
docoptions.Mode = RecognitionMode.Flow;

         // save document in DOC format 
         document.Save(savepath,docoptions);

When I open the document you attached, I get a white background at first.

But after I click the allow editing button, the background is displayed correctly. Is this related to the question?
What I noticed when opening the file at my environment - shifts occur during conversion - do you have such an effect?
