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".
