Feature/Bug? - Black background when using xRender Compositor

[martinandersen3d]

When using OpenGL, there is no blur - but only in parachute, the blur works other places.

When using the xRender Compositor, there is no background and it is hard to see the elements in parachute.

It would be nice to choose background from a dropdown:

• Use a blurbackground
• Use a Solid color background

With options:

• Blur amount
• background transparency
• Background color
