Description daforlynx 2025-05-05 20:30:44 UTC

SUMMARY
I have system monitor sensor pie charts in my taskbar panel. When I need to sync them across my screens, I use the new "clone panel" feature. However, this doesn't seem to replicate the said widgets correctly. They show up as blank until I enter their individual widget configuration settings and click "OK" again.

STEPS TO REPRODUCE
1. Right click a system monitor sensor chart (in my case, a pie chart) in system monitor and select "Add chart as desktop widget"
2. Enter panel edit mode and drag the widgets from the desktop into a panel
3. Clone the panel

OBSERVED RESULT
The charts are initially empty, showing only a blank circle with no label.

EXPECTED RESULT
It should show a partially filled circle, with a label according to what it originally was.

Thanks for the detailed report. Unfortunately, I confirm this on git-master. The cloned panel is correct, except for the pie chart which is empty. I used the CPU pie chart.

When cloning a panel with *any* pie chart system monitor widget, my customization is gone, that's why I move this to plasmashell instead.

For example:

- Insert widget "Individual Core Usage" into a panel
- Right click "Configure Individual Core Usage...", make some customizations, for example change Display Style Pie Chart, Text, and add some custom sensor information like temperatures etc.
- Clone panel
- The cloned panel is a default "Individual Core Usage" widget again, customizations lost.
