Sentry Crash Report:

Description Pas 2019-03-26 09:49:56 UTC 
Application: kwin_x11 (5.13.5)

Qt Version: 5.11.1
Frameworks Version: 5.50.0
Operating System: Linux 4.18.0-17-generic x86_64
Distribution: Ubuntu 18.10

-- Information about the crash:
- What I was doing when the application crashed:
  Initiated resume.
- Unusual behavior I noticed:
  One of the monitors/displays went blank and eventually displayed the no-signal OSD (then turned off the screen because power saving), during this on the other display the Plasma greeter/login screen was unresponsive (no login dialog, only the background and an immovable mouse pointer).

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
