Hyperlinks are no longer followable after saving a pdf file.

Steps to reproduce:
Open a PDF file containing a hyperlink.
Highlight some text, or modify in some way the document.
Save the changes.
Hyperlinks are considered simple text, so no one-finger cursor nor linking is possible.
This malfunctioning happens not only for the modified document, but all opened documents.
Normal behaviour can be restored by zooming in or out, or by focusing another window and then focus back.

Best,
