Thanks for the bug report. Can you let us know if, when the brightness control is missing from the panel, is the slider also missing from 
System Settings -> Display & Monitor ?

Also, when the control is missing, are you able to control the brightness with keyboard keys / shortcuts or is that also not working?

This looks like it might be the same problem as in bug 505290

Thanks

It's not doing it now since I installed CachyOS and KDE 6.5.3.

But for others it was random and system settings control was present. Keyboard brightness button still worked when missing.

Thanks. I'll close this out since it's no longer happening on your system with the different distro and update.
