Comment 1 Justin 2024-05-03 01:20:44 UTC
Hmm, how to edit the original??

Extra notes:
Plasma 6.04
Same behaviour on Wayland and Xorg.
Comment 2 Nate Graham 2024-05-03 19:43:36 UTC
Can reproduce with current git master.
Comment 3 Alan Rempel 2024-05-13 19:11:12 UTC
For me this behaviour is inconsistent -- sometimes when I scroll with my trackpad, the applications grid scrolls, and sometimes it does not. But when my cursor is on or near the scrollbar, scrolling always works. (openSUSE Tumbleweed 20240510, KDE Plasma 6.0.4, KDE Frameworks 6.1.0, Qt 6.7.0)

Yes! I have since discovered that scrolling will work for a few seconds at times then stop again.

Also note, that one the same device on another drive with Kubuntu the scrolling works fine in the application.

Fix Scroll Wheel issue in AllApps submenu of Application Dashboard

Scroll with mouse wheel was problematic in AllApps subsection. It worked
partially, abruptly stopping when hovering over app icons, or just
during mouse wheel scrolling.

The problem is that QQuick WheelInterceptor::findwheelArea() never entered
into its if statement because there are 3 children elements of QML parent,
and their z axis values are 1, 0, 0 respectfully.
FIXED-IN: 6.4.0
