            Bug ID: 408496
           Summary: Magnifier tool makes the document scroll infinitely.
           Product: okular
           Version: 1.7.2
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: david.hurka at mailbox.org
  Target Milestone: ---

SUMMARY
The Magnifier tool can scroll the document, if dragged against the view edges.
However, this scrolling does not stop.

STEPS TO REPRODUCE
1. Open a document with many pages.
2. Select the Magnifier tool (e. g. Ctrl+6).
3. Click and hold near the bottom edge of the view, to see it magnified.

OBSERVED RESULT
Document scrolls like expected.

STEPS TO REPRODUCE
4. Move the magnifier to the middle of the view.

OBSERVED RESULD
Document continues to scroll, so you can’t read anything.

EXPECTED RESULT
Document scrolls only when the magnifier is dragged against the edges of the
view.

SOFTWARE/OS VERSIONS
Okular 1.7.2
KDE Neon 5.15
KDE Plasma Version: 5.15.5
KDE Frameworks Version: 5.58.0
Qt Version: 5.12.0

BONUS
Make the Okular window really small. Then, scrolling goes unpredictably in
various directions.
