Description Martin Hunek 2016-02-16 18:10:09 UTC 
After fresh start and login with multiple screens, opening of any two windows results in kwin_x11 service to STOP. All windows then lost it's upper panel, and any new window renders partially out of primary screen (on upper edge).

By sending KILL to kwin_x11 and starting new instance, kwin resumes its function.

Before the last update crash happened just on fresh start, not after forced restart of X11 by Ctrl+Alt+Backspace. In current version it crashes every time.

Reproducible: Always

Steps to Reproduce:
1. Login with multiple screens connected.
2. Open any two windows.
3. After opening of the second one, kwin_x11 service stops.

Actual Results:  
kwin_x11 service stops.

Expected Results:  
not to.

You can also CONT for a clean segfault exit.
The othe problem is the segfault that triggers this - if you can reproduce it at will, please gdb into the stopped process and dump a backtrace.
