Hello Natale,

first of all, thank you very much for your quick reply. Perhaps I did
not explain the problem well enough. I did not modify a digitally
signed pdf.
In short, the problem is any writer document containing at least one
text box cannot be properly exported to pdf with a digital signature.

The easiest way to reproduce (with the mentioned Version/Build on
debian 10) is as follows.

1) Open libreoffice writer

2) Insert a text box into the blank sheet containing the text "This is
a text box"

3) Export the document to pdf with digital signature

4) Open the pdf with libreoffice draw

=> Look at libreoffice draw's notice about the signature

Greetings,

If you modify a digitally signed pdf this is the correct behavior.
