no transparent with container control

Hi - I can’t seem to get my container control to have a transparent background.
This only happens in windows - on Mac it’s rocking.

I have a container control and on top of that I have a png graphic in a canvas. Even without the canvas overtop, it appears as a white background on my window.
I can assign the backdrop graphic to the CC backdrop - but it still has a white background.
Transparency is set to true - also If I try to runtime that transparent setting, it tells me that this item does not exist

PPRecord.Transparent=true

I’m using 2014 r1

any fix for this?

In your container control ensure that “Custom Color” is set to “OFF”.

That totally solved it - thanks so much!
