Bug 123449

Description:
Setting the background surface of the default outline area "Gliederungsbereich" in the master view will not be seen in the normal view

Steps to Reproduce:
Just open a new presentation and skip using a predefined master (with ESC).
Activate the master slide view now.
Select the outline area and define a colour for the background surface.
=> You will see the whole square filled with this colour, as expected
Now activate the normal view


Actual Results:
You will see a white background only
Even in presentation mode, there is no colour rendered

Expected Results:
The background should be rendered with my selected colour


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes

Additional Info:
Hints: 
- Switching back to master view will show You the colour again
- Doing the same actions with the title area works flawless
