Bug ID: 425421
Summary: [Wayland] Log out causes the CPU utilization to jump
to 100%
Product: plasmashell
Version: 5.19.4
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: twinshadows...@gmail.com
CC: plasma-b...@kde.org

Flags: Wayland+
SUMMARY
After pressing "log out", akonadi_maildispatcher_agent,
akonadi_newmailnotifier_agent, akonadi_indexing_agent, korgac, kdeconnectd
start using 100% of the CPU.
STEPS TO REPRODUCE
1. Log in
2. Log out
OBSERVED RESULT
After pressing log out, all the fans start ramping up. Signing in shows
akonadi_maildispatcher_agent, akonadi_newmailnotifier_agent,
akonadi_indexing_agent, korgac, kdeconnectd using 100% of the CPU.
Strace in htop prints:
"wait4(6735, NULL WNOHANG, NULL) = 0
poll([{fd=3, events=POLLIN}], 1, 1000) = 0 (Timeout)"
Plasma can stutter, freeze or crash.
EXPECTED RESULT
CPU utilization stays below 1%
