Application: krunner (0.1)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-0.rc1.git0.1.fc24.x86_64 x86_64
Distribution: "Fedora release 23 (Twenty Three)"

-- Information about the crash:
- What I was doing when the application crashed: just using KRunner via keyboard shortcut

Setup is
- internal laptop LCD, 2560x1440
- two external LCDs, FullHD

What I see pretty often is, that KRunner is not positioned correctly and on external LCDs is invisible. This happens after some time after clean boot. It works for a few minutes. After that, KRunner is invisible again (but works). Previously, only this issue was observed, now it's accompanied with crashes. Everything (position, no crashes) works correctly when only internal LCD is being used.

The crash can be reproduced sometimes.

-- Backtrace:
Application: krunner (krunner), signal: Segmentation fault
