Background image not showing up - part of new background/design features?

[JHerschel]

Hello there!

We had a SharePoint online site where we added an image to the background (Site Settings > Change the Look > Pick theme > change image) and it is no longer showing up. 

I am guessing it might be part of the new design/ Web Part Section background.  Anybody else having this issue?  See attached image.  Even though we select NONE, it shows up white (not transparent)
