Sentry Crash Report:

Description Jeppe Bundsgaard 2016-01-13 11:01:46 UTC 
Application: plasmashell (5.4.2)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-23-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed:
I am sending mail with thunderbird. I alt+tab and do not release alt before thunderbird is finishing sending, and closes the mail window. 
- Unusual behavior I noticed:
All windows loses their control-line in the top. I cannot move or change windows. I cannot alt+tab. In the status line, the active windows pop up when I hover with the mouse, but I cannot activate them. If I close a window, it does not dissapear from the status line. I can start programs from the K-start-button.

I am not sure this is the correct crash added to the report. There is no crash information when it happens, but one shows up when I reboot. This is the one I am attaching.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted

Comment 1 Martin Klapetek 2016-01-27 02:55:20 UTC 
Thanks for the report

The issue you describe seems like KWin is actually crashing. The
Plasma crash you see on reboot seems unrelated.

In any case, please try updating your Qt to 5.5.x which is available
for *buntu and see if that helps. In our experience it helps a lot with
crashes like these.
Comment 2 Thomas Lübking 2016-01-27 09:11:16 UTC 
Backtrace and plasma dupes look like it's just bug #341497 - which won't fix before Qt 5.6
The description however rather matches bug #356616, would be bug #317765.

You're likely not getting a kwin crash dialog because of bug #353428 ?

=> Please attach the output of "qdbus org.kde.KWin /KWin supportInformation" (the relevant bit is whether you're using compositing or not, ie. whether this is a dupe of bug #317765
Comment 3 Martin Flöser 2016-08-29 07:50:36 UTC 
Please provide the information asked for in comment #2.
Comment 4 Jeppe Bundsgaard 2016-08-29 15:24:29 UTC 
I got a new computer, and changed to Ubuntu Gnome (because of the touch screen support). So I'll close this bug.
Cheers,
