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
