Bug ID: 397547
Summary: System settings crashed on opening “cursor theme” tab
in wayland session
Product: systemsettings
Version: unspecified
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: loic.gro...@gmail.com
Target Milestone: ---
Application: systemsettings5 (5.13.80)
Qt Version: 5.11.1
Frameworks Version: 5.50.0
Operating System: Linux 4.15.0-32-generic x86_64
Distribution: KDE neon Developer Edition
-- Information about the crash:
- What I was doing when the application crashed:
- Open system settings
- Open “Workspace theme”
- Open “Cursor theme”
- Unusual behavior I noticed:
- In wayland sessions, my mouse cursor is much bigger in KDE apps windows and
in Plasma than in GNOME windows (and VLC for some reason) which is why I tried
to change these settings
Neon dev unstable on Bionic
The crash can be reproduced every time.
-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
