Bug ID: 428581
Summary: kwin_wayland crashes when I apply changes in Virtual
Desktops KCM
Product: kwin
Version: git master
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: bugsefor...@gmx.com
Target Milestone: ---
STEPS TO REPRODUCE
1. start Wayland session
2. open System Settings > Workspace Behavior > Virtual Desktops
3. change the number of rows and add or remove virtual desktops
4. click on "Apply" button
5. if kwin_wayland did not crash, repeat the steps 3 and 4. At some point,
kwin_wayland will crash.
EXPECTED RESULT
no crash
SOFTWARE/OS VERSIONS
Operating System: KDE neon Unstable Edition
