Bug 369534

Application: kwin_x11 (5.7.5)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.7.4-200.fc24.x86_64 x86_64
Distribution: "Fedora release 24 (Twenty Four)"

-- Information about the crash:
- What I was doing when the application crashed:

Running with dual screens.
Started a few terminal windows without problem. Starting another windows crashed kwin, leaving the new window borderless.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
