Bug ID: 453697
Summary: kwin_wayland crashed when trying to start plasmashell
from the Overview effect search field
Product: kwin
Version: 5.24.5
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: liubomi...@gmail.com
Target Milestone: ---
STEPS TO REPRODUCE
1. earlyoom killed plasmashell and firefox and QtWebEngine, but kwin_wayland
survived
2. I tried to restart plasmashell by running the plasmashell command via the
Overview Effect search field. This usually works. But now it didn't work as
kwin_wayland crashed.
