PDF popup annotation not rendered

Hello,

I’m trying to capture screenshots of the annotated parts in a document and save them as separate pictures. The code I’m about to post works fine except for sticky note/popup annotations. They don’t seem to get rendered and shown.
Annot_Image1 is the highlight annotation which is shown correctly. Annot_Image2 and 3 are the annotation but the popup is invisible.
Attached you can find the PDF document I’m testing on, the view in a PDF viewer and the output of the C# code.
How can I get this annotation to render properly so I can capture it in an image?

Best regards,
Filip
