Application: systemsettings5 (5.13.2)

Qt Version: 5.11.1
Frameworks Version: 5.47.0
Operating System: Linux 4.17.3-1-default x86_64
Distribution (Platform): openSUSE RPMs

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

enter systemsettings5 -> application style -> window decorations 

this happens in dual screen setup with one monitor being standard dpi and the other one is hidpi AND while systemsettings5 is currently on the standard dpi monitor

- Unusual behavior I noticed:

in dual screen setup, when one monitor is hidpi and scaled to 2, the other on is standard dpi with scale of 1, entering systemsettings5 -> application style -> window decoration crashes systemsettings5
this happens only when systemsettings5 is found on the standard dpi monitor.

if systemsettings5 is found to be on the hidpi monitor, then it opens window decorations without crashing.
additionally to this, apply button is disabled until the window is resized manually.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
