Created attachment 164312 [details] Screenshot SUMMARY Only the Line Chart graph is shown. Legend, Grid Lines, Title, and Axis labels are all missing. All line chart details show sometimes on creation, sometimes not. Sometimes the widget gets created correctly, but then they disappear on plasmashell reload. Widget added to the desktop seem fine. Dragging a widget from a panel to the desktop fixes it. Dragging it back to the panel breaks it again. STEPS TO REPRODUCE 1. Add system monitor widget to panel 2. Right click on widget and select 'Configure System Monitor Sensor...' 3. Change the Display Style to 'Line Chart' 4. Click 'Apply' 5. Click on 'Sensor Details' tag 6. Add any senors such as memory percentage 7. Click 'Apply' OBSERVED RESULT Legend, Grid Lines, Title, and Axis labels are all missing. EXPECTED RESULT Legend, Grid Lines, Title, and Axis labels are all shown SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch (available in About System) KDE Plasma Version: 5.27.10 KDE Frameworks Version: 5.113.0 Qt Version: 5.15.11 ADDITIONAL INFORMATION Wayland Sceenshot shows 3 widgets created at the same time. They should all have Legend, Grid Lines, Title, and Axis labels. They will randomly show details after plasmashell reload but I haven't observed them all working at the same time.

Upon further test, this is a floating panel issue. Toggling on floating panel breaks the widgets. Toggling off floating panel fixes them.
Just did a fresh install of Plasma 5.92.0 to test Plasma 6 RC1 and the issue persists. Toggling Floating panel seems to fix it. If the widget is added to a floating panel, it's broken until I toggle floating panel. The opposite seems to work as well.
Aha, this is one of those things that was fixed in Plasma 6.2
