Bug ID: 417686
Summary: Certain KDE/Plasma components don't respect touchpad
scroll direction setting in Wayland with Qt 5.14.x
Product: plasmashell
Version: 5.18.0
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: generic-wayland
Assignee: plasma-b...@kde.org
Reporter: bsmith7...@gmail.com
Target Milestone: 1.0
SUMMARY
In certain parts of Plasma, the Touchpad scroll direction setting is reversed
when running a Plasma Wayland Session with Qt 5.14.x. This bug started for me
in Plasma 5.17 when Manjaro & Arch updated to Qt 5.14. It still persists in
Plasma 5.18 with Qt 5.14.1. Most apps respect the setting, but scrolling
direction is reversed in the System Settings app, the Application Launcher, and
the wifi networks list in the plasma-nm taskbar applet. [Scrolling in other
areas may also be affected; these are the only ones I've noticed.]
STEPS TO REPRODUCE
1. Open a Plasma Wayland Session with Qt 5.14.x.
2. In System Setttings, Input Devices, Touchpad: Choose your preference for
"Invert Scroll Direction (Natural Scrolling)".
3. Attempt to scroll using the touchpad in the list of System Settings modules,
the application launcher, or the wifi networks in the plasma-nm taskbar applet.
OBSERVED RESULT
The scrolling direction is opposite of the setting.
EXPECTED RESULT
The scrolling direction is the same as the setting.

ADDITIONAL INFORMATION
The bug is not present in Kubuntu 19.10 [with Plasma 5.17] or 20.04-nightly
[with Plasma 5.18] because they build against Qt 5.12.x.
