            Bug ID: 412991
           Summary: [okular] Scrolling with the scroll bar lacks and is
                    slow
           Product: okular
           Version: 1.8.2
          Platform: Archlinux Packages
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: mail at rainer-finke.de
  Target Milestone: ---

Scrolling in okular with the scroll bar is slow and lacks. If I click on the
scroll bar and keep the left mouse button pressed and I move the mouse fast up
and down several times, then okular starts to lack already quite a lot. If I
then release the left mouse button, okular continues to scroll up and down. It
feels like watching a movie, it recorded all the mouse movements and shows them
in slow motion.

STEPS TO REPRODUCE
1. Open in okular (Wayland) a PDF with several pages
2. scroll up and down

OBSERVED RESULT: scrolling lacks and continues for several seconds without user
interaction


EXPECTED RESULT: scrolling feels natural and it stops quite fast
