Could not repro, but might be related to Qt 6.10? Operating System: Fedora Linux 42 KDE Plasma Version: 6.5.80 KDE Frameworks Version: 6.19.0 Qt Version: 6.9.2 Kernel Version: 6.16.12-200.fc42.x86_64 (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 3600 6-Core Processor Memory: 16 GiB of RAM (15.5 GiB usable) Graphics Processor: AMD Radeon RX 6600
Nice catch. Can repro on 6.6 dev (git-master like a week old), but only when choosing the second alternative "Application dashboard - a fullscreen application launcher", the other entries work fine. Operating System: Arch Linux KDE Plasma Version: 6.5.80 KDE Frameworks Version: 6.19.0 Qt Version: 6.10.0 Kernel Version: 6.17.2-arch1-1 (64-bit) Graphics Platform: Wayland
Correction: it's more like the original reporter noted, just selecting different things in Show Alternatives... rather than one particular option. It's likely easily reproducible. Sorting the issue to the Application Launcher component.
This is a Qt bug: https://bugreports.qt.io/browse/QTBUG-139626 It's already fixed for Qt 6.10.1
