screenshot showing the black panel on system settings
SUMMARY
After sleep/resume
STEPS TO REPRODUCE
1. Open system settings, click on "system information"
2. Click Sleep, to send the PC to sleep
3. Wake the computer and login again.
OBSERVED RESULT
The right-hand pane which previously showed the system information is now
black.
Clicking other sections (e.g. audio) shows some info, but KDE connect or
printers remains black
Clicking back to system information remains black again.
To workaround: resize the window, and the panel stops being black.
See this video for a demonstration https://www.youtube.com/watch?v=WAL3IV__HOo
EXPECTED RESULT
Expect to see system information, without a black panel
