This issue affects me on Ubuntu Bionic 18.04 if I have a Firefox window
open with a frequently changing title bar. It seems that plasmashell
cannot keep up with re-rendering the label on the task bar buttons. The
specific Firefox operation that triggers it for me is using the HTML5

Still present in kubuntu 17.10, occuring anytime a screen's resolution is
changed.
Typically using 70-100% cpu, returning to <10% when plasmashell is killed and
restarted.

I see the same on Kubuntu 16.04 LTS. Removing all animated(!) icons from

Kubuntu 17.4, and plasmashell startup is (still) a disaster. 21 cpu

Or does someone really expect me to log in and then come back half an

Same on "Kubuntu 16.04.2 LTS" with 4.8.0-52-generic kernel.
After automatic switching access points the process "plasmashell --shut-up"
generates 100% CPU load.
In my case, it is related to the Skype 4.3.0.37 application.
As soon as I kill the Skype tray icon, the "plasmashell --shut-up"

I will add that on my machine (Ubuntu 16.04.1) increases in CPU usage get
triggered also by changes in the network connectivity.
For example, if the WiFi connection drops and Skype tries to connect, Plasma
goes immediately to 100%. Killing Skype reduces the CPU usage to 15-30%, but it
stays
I also have this issue on 16.04. I can restart plasmashell, but this
only fixes the issue for a few hours, not good when I usually leave my
machine running for week on end.

While I am annoying everyone with my spleen venting, let me add one more
thing. I can no longer mount my network shared folders automatically
either. There is a nice new feature on dolphin to add these as samba

Adding to my comment. My upgrade has been a mini-disaster. First, the
