Application: plasmashell (5.8.4)

Qt Version: 5.7.0
Frameworks Version: 5.30.0
Operating System: Linux 4.8.7-040807-generic x86_64
Distribution: KDE neon Developer Edition

-- Information about the crash:
- What I was doing when the application crashed:
Plasma crashed when i was hovering the mouse over thetaskbar entry for Kontact, running via Xorg while Plasma ran in Wayland.
- Unusual behavior I noticed:

The mouse cursor moved smoothly over top X applications, but stuttered and moved with jerky motion when moving over the plasma panel.

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