SUMMARY STEPS TO REPRODUCE 1. Open the system settings, go to colors KCM 2. With the mouse wheel(!), change the displayed schemes from "All Schemes" to "Light Schemes" or "Dark Schemes" 3. Try to scroll the grid view with the mouse wheel (either after only moving the mouse to the grid view or after clicking into the grid view) OBSERVED RESULT The grid view doesn't scroll EXPECTED RESULT The grid view should scroll SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Neon Unstable Edition (available in About System) KDE Plasma Version: 5.15.80 KDE Frameworks Version: 5.59.0 Qt Version: 5.12.0 ADDITIONAL INFORMATION
For some reason the contentHeight of KCM Controls GridViewInternal (the grid view) becomes 0 when items are filtered out and then the Wheel Handler doesn't scroll anymore. Very odd. Looks like a Qt bug to me, will try to find a simple testcase to reproduce and report to Qt.
cannot reproduce on Plasma 5.18. Operating System: Arch Linux KDE Plasma Version: 5.18.0 KDE Frameworks Version: 5.67.0 Qt Version: 5.14.1
Yup, this is fixed now.
