Bug ID: 439417
Summary: Rethink drag scrolling with left mouse button
Product: okular
Version: 21.04.2
Platform: unspecified
OS: Unspecified
Status: REPORTED
Keywords: accessibility, usability
Severity: normal
Priority: NOR
Component: general
Assignee: okular-devel@kde.org
Reporter: david.hu...@mailbox.org
CC: visual-des...@kde.org
Target Milestone: ---
Flags: Brainstorm+, Usability+
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:
