Bug ID: 366329
Summary: Crash when dragging widget to secondary monitor (dual
monitor system)
Product: plasmashell
Version: 5.7.1
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: briana...@hotmail.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.7.1)
Qt Version: 5.6.1
Frameworks Version: 5.24.0
Operating System: Linux 4.6.4-301.fc24.x86_64 x86_64
Distribution (Platform): Fedora RPMs
-- Information about the crash:
- What I was doing when the application crashed:
Dragging desktop widget to secondary monitor causes Plasma to crash. Only
happens every few times when moving the widgets and seems to happen with all
widget types I have tried.
- Unusual behavior I noticed:
Upon crash desktop reverts to a "generic" background and loses my wallpaper
config.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
