How recent is your "compiled from sources"?
Comment 2 Siddhartha 2020-02-03 22:58:49 UTC 
Built from the latest master (commit on Feb 1): okular-git-r8658.c6d937ab0
Comment 3 Albert Astals Cid 2020-02-04 23:08:26 UTC 
Garg, i shouldn't have merged the code from David from phabricaotr without using invent.

The unittests would have found it.

David can you please fix this mess?

Yes, both problems can be removed after reverting 0d5bd0bc43b26e94833b133afc2fbbdb66346652
Comment 6 Laura David Hurka 2020-02-05 13:43:30 UTC 
I think it is a problem because Print Preview opens a new window with another ToggleActionMenu? I will try to investigate, maybe tomorrow.

Maybe it is a good Idea to drop ToggleActionMenu. ...
Comment 7 Laura David Hurka 2020-02-07 15:23:50 UTC 
To fix this, just d->aMouseModeMenu needs to be nullptr-initialized in the PageView constructor. Apparently I forgot that when I created D21971.

How can I create a merge request? On the invent.kde.org website, I am apparently not allowed to do so. Via the git command line, I get an error that I am not allowed to do so. And via email, I get a reply that I am not allowed to do so...

Can you fork the repo? If so, just commit into your clone then create merge request.
