            Bug ID: 421399
           Summary: Different setting of continuous view mode per windows
                    does not work correctly
           Product: okular
           Version: unspecified
          Platform: Archlinux Packages
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: me at jonas-schuermann.name
  Target Milestone: ---

I often have multiple windows of Okular open with different documents. Some of
these documents are slides that I browse with continuous view off, but some are
papers/longer documents that I browse with continuous view on. However if I
turn on continuous view in one window, turn it off in a second window and come
back to the first strange things happen. The view blocks completely until I
toogle continous view 2 more times, the view is displayed continuously although
the menu setting says otherwise, and so on. It is really annoying and has been
like this for some years now. I hoped that the recent changes of saving
continous view mode for every distinct file would solve the problem but it's
even worse now. I only open one more file, the continuous view flag gets loaded
and locks up the other windows. The problem seems to be that this boolean is
somehow global although it really should be a per-window thing.


STEPS TO REPRODUCE
1. Open one document, turn on continuous view
2. Open a different document in a second window, there turn off continous view
3. The first window should act strange. If the problem doesn't show right away
try toggling the setting a few times while switching windows, it should appear
pretty soon.

OBSERVED RESULT

Changing continous view in one document affects all other windows in strange
ways.

EXPECTED RESULT

Continuous view should be a flag that is distinct for each open window.
