Hello, Comments created in a Writer document are not correctly exported to PDF, or at least not in a format that the Poppler backend of Evince and qpdfview on Linux can read. I am attaching two sample documents. The exported PDF shows an annotation, but it is by "Unknown author" and does not contain the text of the comment I created in LO Writer. Thanks for looking into this.
Created attachment 113644 [details] source ODT
Created attachment 113645 [details] exported PDF, no comment text, "Unknown" author
Created attachment 113646 [details] The way I see it in Atril (Evince) PDF viewer, Poppler backend
Per the discussion in bug 60126, this should be reported to Poppler. *** This bug has been marked as a duplicate of bug 60126 ***
