--- Comment #2 from David Edmundson <kde at davidedmundson.co.uk> ---
I've been investigating, and I think we're misreading the logs.

What should happen is Plasmashell disables session management and immediately
responds to the session manager that it is ignoring the request.

As soon as all session controlled apps have finished, ksmserver starts killing
everything else, including plasmashell.
A bit quirky, but does seem to work.

The fact that we're in SMSDie is fine, the fact that it's timing out is weird.

---

There's a bug in plasmashell, somewhere - ideally I need a gdb trace of
plasmashell when it's in this high CPU state. Though I appreciate that will be
hard to get.

---

What's also weird is it thinks kwin_x11 is a client, it should detect that it's
the WM and treat it differently.
Can I have your ~/.config/ksmserverrc
---

Also can you add 
export QT_LOGGING_RULES='org.kde.kf5.ksmserver.debug=true'

to something that gets sourced before login (/etc/profile.d/debug.sh is one of
the most reliable)

and then reattach a new log if you can reproduce after starting with this env
set. It'll print a lot more for ksmserver.
