Collection display in viewport not consistent with final render

I am starting to use RPR for personal project in blender, and I notice an unexpected behavior regarding collection visibility.


The test is a simple cube in a collection called "test" inside another collection called "source" :
The collection test is instanced in the scene ( because I noticed the issue while using instance and trying to hide the source to the render )
Bellow the test scene ( cube going inside the plane is the original one, the cube on the plane is the test collection instance )


Base scene

The source collection is hidden for rendering so as expected if I do a regular render here is what we get :
normal render ( NOT VIEWPORT )

But with the same set up, in the viewport I still get the source collection to show :

viewport render

To be sure I even unchecked the "visible in viewport" icon in the outliner for both, and it works only for the instance collection :


So this is a bit annoying, because I can't really get the viewport rendering to work as I want when I need to test a scene with instances because the sources of those instances are always visible.
However, for final render, it is not a problem and it works as expected.


Thank your for your help

To reproduce the issue, simply render the scene using viewport render, and then render the scene using top menu render > render image.
