Plasmashell 100% Usage While WiFi Reconnecting

Help
1

My WiFi configuration is a bit wacky and sometimes disconnects and stays in a “loading” animation until I click on it in the system tray. This happened the other day when I was about to leave somewhere, so I just closed my laptop to deal with it later. When I pulled my laptop back out later, it was very hot. I unlocked it and the reconnecting animation was still showing and plasmashell was using 100% CPU. I had to kill and restart plasmashell to fix it. It really looks like bug 356479 which was marked as closed in 2020, but relates to animations causing 100% usage in plasmashell. Should I try to recreate the bug and reopen the bug? Is anyone else still experiencing this?

My setup:
I am using Asahi Linux on an M1 Macbook Air, and the arm architecture might be the cause.
Arch Linux Arm
KDE Plasma: 5.27.5
KDE Frameworks: 5.107.0
Qt: 5.15.10

I too have this problem, but only when using the nVidia graphics card. The wait pointer spins manically and the fans start running fast and plasmashell can use up to 100% cpu on 4 of my 16 cores. Doesn’t happen using the intel graphics. It has only started happening since I upgraded to openSUSE 15.6. Thank you for posting on the subject.

It happens when NetworkManager is checking for full connection and displays a wait pointer over the taskbar icon.
