I believe Okular has been upgraded to KF5 with the release of 16.12.0-1. With this new version, however, annotations saved to PDF files by earlier versions can't be deleted. Expected behavior: Right click > Delete > Causes annotation to be deleted. Current behavior: Right click > Delete is grayed out. New annotations are unaffected by this.
Any chance you can share a pdf where this happens?
Of course. Please have a look at the following link: https://mega.nz/#!44M0kTxL!dOijXerRTxBiB09Q8YSW6Nbyi34IGncFO_CKmFLjFDQ (This is a textbook so it's somewhat heavily annotated).
Confirmed with today's okular git master and poppler 0.48.0. There are annotations (e.g.) on page 2/9, and the 'Delete' menu entry in the context menu is grayed out.
PS: I can delete those annotations with okular 0.26.1 from Debian testing.
Oliver (since you seem to have both things at hand): Are the obey DRM limitations options checked the same way in 0.26.1 and git master?
Yes, they are both set to "yes, do obey DRM".
