Created attachment 173641 [details] plasma freezing after hovering over launcher SUMMARY Quickly hovering over the Application Launcher categories freezes plasmashell and leaks memory. STEPS TO REPRODUCE 1. Quickly move the mouse above the categories in the application launcher See attached video for example. OBSERVED RESULT Plasma quickly freezes with 100% CPU usage on one thread and starting to consume memory. EXPECTED RESULT The system should not freeze and not consume memory SOFTWARE/OS VERSIONS Operating System: CachyOS Linux KDE Plasma Version: 6.1.90 KDE Frameworks Version: 6.5.0 Qt Version: 6.8.0 Kernel Version: 6.11.0-rc7-1-cachyos-rc (64-bit) Graphics Platform: Wayland Processors: 12 × 11th Gen Intel® Core™ i5-11400 @ 2.60GHz Memory: 31,2 GiB of RAM Graphics Processor: Mesa Intel® Arc ADDITIONAL INFORMATION I was misusing the application launcher as idle "fidget spinner" while talking and thinking, when the observed behavior kicked in. Of course this is not exactly normal(tm) user behavior, but seems noteworthy nonetheless.
Same issue observed on Plasma 6.1.4 (Fedora 40 KDE, KDE frameworks 6.5.0, Qt 6.7.2, kernel 6.10.9-200.fc40.x86_64. Using Wayland, Application Launcher set to list apps in a grid)
Can reproduce, but only with kickoff set to display as a grid. Kickoff as list works without issues. plasmashell output shows a lot of org.kde.plasma.kickoff/contents/ui/KickoffGridView.qml:67:5: QML GridView: Binding loop detected for property "rows" which may be related.
