Application: kwin_x11 (5.13.5)

Qt Version: 5.11.1
Frameworks Version: 5.50.0
Operating System: Linux 4.13.0-45-generic x86_64
Distribution: KDE neon User Edition 5.13

-- Information about the crash:
- What I was doing when the application crashed:
When I turned on the computer after suspending it, there was the drkonqui notification saying the trace is useful (hopefully it actually is). I didn't loose the desktop effects or anything so I guess it restarted without me noticing at all.
- Graphic cards info:
Asus ROG laptop with
· Nvidia GTX 960M with propietary drivers 396.54 (always using this one)
· Intel HD 530

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
