Bug 395906

Application: kwin_x11 (5.12.5)
 (Compiled from sources)
Qt Version: 5.9.6
Frameworks Version: 5.47.0
Operating System: Linux 4.17.1-gentoo x86_64
Distribution: "Gentoo Base System release 2.6"

-- Information about the crash:
- What I was doing when the application crashed:
I was testing the effects of KDE, I just enabled the Composer, I changed it to OpenGL 3.1 and the rest is in the standards. When you try to drag any window to the edges, KWin closes unexpectedly.

- Unusual behavior I noticed:
KWin restarts to "seemingly" try to "find out" to which size the window would be resized.

- Custom settings of the application:
Render Infrastructure.

The crash can be reproduced every time.

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