How to get a transparent background in detail view in layout

Is there a trick to make overlapping detail views (in layouts) have fully transparent backgrounds when printing? The backgrounds show when printing to .pdf and .png files.

View>capture>to file removes the background, but leaves the border lines framing each detail view, so that method does not seem to work very well for me.


Got the same problem, i’m working on “art style” of my drawing in layout, and this boders me a lot. Couldn’t find solution so far.
