Plasmashell high CPU use

Just started having this today. High CPU use on Plasmashell. I updated my system and rebooted but the problem persists. Did a quick Google and found most issues from a couple of years ago and don’t seem related. Any suggestions?

tried lts kernel already?
or give some logs :wink:

I killed one of the plasmashell sub-processes and the issue went away (presumably until I reboot). I don’t think this is a kernel issue but I could be mistaken.

Which log files would be the most helpful for diagnosing Plasmashell? I’m not very adept at log files in Linux but I can figure it out if I know which ones would be helpful.
