Bug ID: 382786
Summary: KWin crashes and moves apps couple pixels higher
Product: kwin
Version: 5.10.2
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: maila...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.10.2)
Qt Version: 5.7.1
Frameworks Version: 5.35.0
Operating System: Linux 4.4.0-87-generic x86_64
Distribution: Maui
-- Information about the crash:
Just browsing firefox on 4k screen with VirtualBox open and the Virtualbox apps
move up so title bars aren't visible after KWin crashes. Only effect is a
screen flash and the apps have moved uo. Easily fixed by moving them down as
Kwin restarts instantly
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
