Created attachment 127004 [details] plasmashell log SUMMARY I'm currently running Plasma in a non-standard setup, though I believe it should still function in this setup. I'm running KDE Plasma with i3wm as the window manager instead of Kwin. `plasmashell` will freeze, resulting in a non-changing, non-interactive bar, until I kill the process and run `plasmashell` again manually. Nothing in particular other than time seems to elicit this behaviour. STEPS TO REPRODUCE 1. Leave plasmashell running 2. Wait until it freezes SOFTWARE/OS VERSIONS Linux/KDE Plasma: 5.18.3 (available in About System) KDE Plasma Version: 5.18.3 KDE Frameworks Version: 5.68.0 Qt Version: 5.14.1 ADDITIONAL INFORMATION I've attached a log of multiple instances of plasmashell output before it freezes. Every freeze seems to be prefaced with the line: libkcups: Renew-Subscription last error: 0 successful-ok Leading me to believe libkcups may be the culprit here, though I'm not sure how to investigate further.
I doubt it's cups related from the log. Define frozen. Can you right click on the desktop? If it is frozen, I need a backtrace. sudo gdb --pid `pidof plasmashell` then type "bt" when it loads.

Frozen as in... right clicking on the plasma bar doesn't do anything, all of my widgets (like CPU monitor, memory monitor, upload/download speed) have stopped changing. The time isn't changing either. I've attached the backtrace. Thank you for your prompt response :)

Ah, didn't know I had to do that.
I'm having the same issue on NixOS, and looking at the stacktrace it seems to be the same as Andrew's. I'm attaching my stacktrace since NixOS basically pins all the dependency versions and as a result they show up in the paths of the shared libraries loaded. Might be helpful.

Hello and thank you again for the bug report! Unfortunately we were not able to address it yet, nor even manage to reproduce the issue ourselves. Can we ask you to please check if this issue is still happening with Plasma 5.27? If it is, please change the status to REPORTED. Thanks a lot!
