Sentry Crash Report:

Description xunilhcra 2016-11-09 03:11:51 UTC 
Application: plasmashell (5.8.3)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.8.6-2-default x86_64
Distribution: "openSUSE Tumbleweed"

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

Pressed the super key + "L".

- Unusual behavior I noticed:

This caused my dual monitor setup to lose their correct resolutions. By continuing to cycle through the different resolutions by pressing the super key + "L" it continued changing the resolutions on both monitors, with either one going completely black at times. Only one or the other monitor would have the correct resolution at a time, not both. Eventually I went into the Plasma Display and Monitor settings and noticed that the alignment was way off for both monitors. I realigned the displays and then had to kill 2 plasmashell processes to get my wallpaper showing again.

Superkey + L is a strange default, because I pressed it by accident and then this happened. It also is a confusing default because Windows users are used to this keyboard shortcut to lock the desktop. Maybe make Superkey + L actually lock the desktop rather than this behaviour?

-- Backtrace:
