LibreOffice Writer displays the text boundaries on its pages, shown by small L-shapes at the four corners.
Having upgraded to version 184.108.40.206 recently, those boundaries have disappeared.
I have checked that View > Text Boundaries is ticked.
How can I get those text boundaries back again, please?
I have noticed that this is happening only on some of my documents, not all of them. That means that it is document-specific. This confuses me greatly!
