Bug ID: 487815 Summary: After changing the CPU bar chart to application list, the entire shell freezes due to a binding loop Classification: Plasma Product: plasmashell Version: 6.0.5 Platform: Arch Linux OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: System Monitor Assignee: plasma-b...@kde.org Reporter: fifis.hi...@gmail.com CC: ahiems...@heimr.nl, notm...@gmail.com Target Milestone: 1.0 SUMMARY After I accidentally changed the display style of the CPU usage tray sensor to ‘Application list’, the entire shell froze; Alt+Tab and shortcuts (e.g. Terminal, Ctrl+Alt+T) still work. Rebooting changes nothing – it still freezes. STEPS TO REPRODUCE 1. In the CPU usage monitor in the system tray, change ‘Bar chart’ to ‘Application list’ 2. The system tray and desktop freeze and become unresponsive. OBSERVED RESULT After `kquitapp5 plasmashell` and `kstart5 plasmashell`, here is the console log: ``` (base) [avk@UL0012159 ~]$ kstart5 plasmashell (base) [avk@UL0012159 ~]$ kf.plasma.quick: Applet preload policy set to 1 file:///usr/share/plasma/plasmoids/org.kde.desktopcontainment/contents/ui/main.qml:196:25: QML FolderViewDropArea (parent or ancestor of QQuickLayoutAttached): Binding loop detected for property "minimumWidth" file:///usr/share/plasma/plasmoids/org.kde.desktopcontainment/contents/ui/main.qml:196:25: QML FolderViewDropArea (parent or ancestor of QQuickLayoutAttached): Binding loop detected for property "minimumWidth" qml: The backend got an unknown wallpaper provider type.
