            Bug ID: 439417
           Summary: Rethink drag scrolling with left mouse button
           Product: okular
           Version: 21.04.2
          Platform: unspecified
                OS: Unspecified

          Severity: normal
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: david.hurka at mailbox.org

SUMMARY
https://invent.kde.org/graphics/okular/-/merge_requests/444 
indicates that drag-scrolling with cursor wraparound does not work very good.

After merging that fix, it will not crash on Wayland anymore, and show the
traditional “wrap” behavior on X. The errorneous behavior if scrolling on a
touchscreen is already fixed.

But as seen e. g. in https://bugs.kde.org/show_bug.cgi?id=421040, this behavior
is not necessarily desirable. I like this behavior in Okular, but at the same
time hate it in KiCad. Blender simply freezes the cursor while drag-scrolling,
and in addition hides it. Maybe that is less annoying and more portable?

STEPS TO REPRODUCE
1. Open a long document.
2. Scroll using the Browse tool and left mouse button dragging, until you reach
a screen edge.

OBSERVED RESULT
If not on Wayland, the cursor “wraps” to the opposite screen edge.

EXPECTED RESULT
?

ADDITIONAL INFORMATION
Useful link from Aleix, maybe read up what may work on Wayland and what not:
