Bug ID: 478081
Summary: Inconsistent Smooth Scrolling in KDE Plasma System
Settings Sidebar on Wayland
Classification: Applications
Product: systemsettings
Version: 5.90.0
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR

Though it may be hard to tell since OBS records at 60 FPS, before I open the
"Colors and Themes" menu, the scrolling appears very choppy, but after going in
and out of the menu it is buttery smooth.
In the KDE Plasma System Settings application, the main sidebar exhibits laggy
scrolling behavior with a notably low frame rate, not matching the native
refresh rate of 165Hz. This issue is initially present upon opening the System
Settings. However, navigating to the "Colors and Themes" section and then
returning to the main sidebar rectifies the issue, resulting in smooth
scrolling consistent with the expected 165Hz refresh rate.
STEPS TO REPRODUCE
1. Open the system settings application
2. Scroll up and down on the main sidebar with a high refresh rate monitor
OBSERVED RESULT
Choppy scrolling not consistent with other applications where the scrolling is
buttery smooth.
EXPECTED RESULT
The smooth scrolling should be at 165hz.
