Qt Version: 5.5.1
Operating System: Linux 4.2.6-301.fc23.x86_64 x86_64
Distribution: "Fedora release 23 (Twenty Three)"

-- Information about the crash:
- What I was doing when the application crashed:
Adjusting position of the displays

- Unusual behavior I noticed:
KDE frequently crashes when adjusting resolution or doing more or less anything when using a 4k monitor (Dell P2415Q) with 2 1080p monitors

- Custom settings of the application:
Have a 4k monitor
Nvidia binary driver

The crash can be reproduced every time.

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