Attachments: The KCM showing the black box instead of the preview

Description Ken Vermette 2015-01-25 23:43:27 UTC 
When viewing the Window Decorations KCM if you switch away (to the Widget Style or Gnome Application Style sections) returning to Window Decorations will present a blac box over the preview area. 

If you switch back to the main System Settings overview and re-load the KCM it will render again correctly until you replicate the problem.

Reproducible: Always

Steps to Reproduce:
1. Go to System Settings -> Application Style (it will give you a preview of window decorations)
2. Switch away to Widget Style or Gnome Application Style
3. Switch back to Window Decorations

Actual Results:  
The decoration preview is now a black box.

Expected Results:  
The decoration preview should show the window styles

Tested on Kubuntu 15.04
Plasma 5.1.95
Qt 5.3.2
Frameworks 5.6.0
