Bug ID: 362461
Summary: Plasma crashes when switching between Windows host and
VirtualBox Kubuntu 16.10 (with Plasma)
Product: plasmashell
Version: 5.5.5
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: martin.h...@posteo.de
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.5.5)
Qt Version: 5.5.1
Operating System: Linux 4.4.0-21-generic x86_64
Distribution: Ubuntu 16.04 LTS
-- Information about the crash:
- What I was doing when the application crashed: Simply switched back to
VirtualBox client (which is the Kubuntu 16.10 system). The crashes re-occure
frequently but not always.
- Unusual behavior I noticed: Mouse integration seems to have a difference in
position of mouse pointer sometimes. Mouse pointer is visible approx 30 pixel
to the right and bottom of "real" position for the Kubuntu VirtualBox client.
E.g.: When I want to resize a window, I gently have to pull the mouse pointer
downwards to the right until I see the resize pointer symbol on screen.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
