We have started using the new Aspose.Words for SharePoint library version - 3.0.2 and have observed an issue which was not observed in previous version - 2.7.0
When a word document contains a flow diagram (for example) created on a page with various word drawing tools along with some subsequent text. Then, while conversion to PDF, the diagram/canvas area overlaps with the subsequent text on the page.
One unique thing that I observed with the canvas area is that the parent most holding shape (square frame) in the document has a gradient fill background area.
