Bug ID: 391673
Summary: Kwin is having a lot of bugs recently using some of my
applications on plasma 5.12
Product: kwin
Version: 5.12.3
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: luismora1...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.12.3)
Qt Version: 5.9.1
Frameworks Version: 5.43.0
Operating System: Linux 4.13.0-36-generic x86_64
Distribution: Ubuntu 17.10
-- Information about the crash:
- What I was doing when the application crashed: Using Inkscape, Kdenlive and
Audacity, then, Kwin stopped working and then, the desktop froze, i wasn't able
to do or save anything, it really bothers me, because i like KDE, but can't
understand why this happens when i work with graphic tools and audio tools.
Maybe could be the drivers, but without KDE i didn't have any of those issues.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
