Public bug reported: Application: kwin (4.11.11) KDE Platform Version: 4.13.3 (Compiled from sources) Qt Version: 4.8.6 Operating System: Linux 3.13.0-46-generic x86_64 Distribution: Ubuntu 14.04.2 LTS
-- Information about the crash: - What I was doing when the application crashed: This occurs somewhat regularly upon logging into kubuntu. On other instances it is when I return from either hibernate or suspend to RAM. The result is the windows have no title bar and cannot be closed. i have to restart the computer to get it to work again. Sometimes I have to restart several times. I tried to switch to a terminal and use killall kwin and then DISPLAY=:0 kwin to restart it but this has not yet worked. The crash can be reproduced sometimes. -- Backtrace: Application: KWin (kwin), signal: Aborted Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
