I've seen something similar maybe twice over the years but nothing recent. All my machines use NVidia with their driver. Good luck, Mark

Yeah, it's nvidia using the binary driver. But I've never had this issue before. It only started happening today when I booted up the machine.

Logging out and back in again usually fixes it. I've had this problem for at least 2 years, can't find the cause. I sleep/resume a lot and figured it was some race condition. I have a Konsole shell auto-open one resume or logon so I can drop to the shell and issue `killall plasmashell && plasmashell &`. I've even tried starting with a fresh home directory and have not seen a difference. I don't use any plugins either. Do you have an nvidia card? This machine that constantly has this issue does, but my laptop (intel graphics) does not. Dan
[gentoo-user] plasmashell becomes sluggish with 100% CPU usage
Anyone noticed anything lately with plasmashell? I think it started happening after Qt was upgraded from 5.15.3 to 5.15.4. At login, the desktop is very unresponsive and sluggish. Mouse clicks take over a second to register. The plasmashell process is hogging one core of the CPU to almost 100%. It only happens on login. Logging out and back in again usually fixes it.
