Description phillip 2016-06-09 00:30:05 UTC
Application: kwin_x11 (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-22-generic x86_64
Distribution: Ubuntu 16.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I tried to open Dolphin. Dolphin opens successfully but kwin crashes and all windows from every desktop are suddenly visible all at once. I do kwin --replace to get things back to normal.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted

Comment 1 Thomas Lübking 2016-06-09 05:59:15 UTC
This is a crash on exit, bug #363251
Likely triggered in the "dead" kwin process when calling "kwin_x11 --replace" and not the actual problem (ie. not related to "opening dolphin" and all decos gone)

Can you please post the output of "qdbus org.kde.KWin /KWin supportInformation"?

> Plugin: org.kde.kwin.aurorae
quelle surprise...

run "kcmshell5 kwindecoration" and switch to breeze, do the crashes still happen afterwards?
Comment 4 phillip 2016-06-10 16:33:06 UTC
That does appear to have fixed it. No more kwin crashes.
This seems to have started for me after a recent Kubuntu 16.04 update. It did not cause me any trouble until a couple days before I submitted the ticket.
Thank you for your help, Thomas. If there's anything else I can provide, let me know.
Comment 5 Thomas Lübking 2016-06-10 16:38:00 UTC
This will be the linked bug, upstream bug is https://bugreports.qt.io/browse/QTBUG-53452
There's unfortunately not much you can doother than not using aurorae.
