Cannot reproduce in 2.83.7

Does this happen in any file/nodetree?
Is this only an issue in 2.83.7? Do other previous https://download.blender.org/release/ work?
Note 3.37 added support viewers inside nodegroups 8dbd8a8d92, but I doubt this is related?

@lichtwerk Okay, I found the reason.
Looks like it is smart feature, not a bug.
Strength of output node changes to compensate current exposition.

But as far as exposition do not work with Scene lights/world enabled, it causes issues in this case.
I mean this: blender/blender#81991 (Viewport, option Scene Ligts and Scene world influence to color management.)

So in this case it is about addon design, I think.

Ah, yes.

Will have a look at blender/blender#81991 next, might be the case that if blender/blender#81991 is solved, this report would be solved, too?

@lichtwerk
Yep. Anyway blender/blender#81991 should be solved before this.
And I am not sure it is a bug. We need to call addon developer.

So, while it is unfortunate that we have this thing going on with blender/blender#81991, I think the Addon generally does the right thing.
And we cannot really work around it because you could have multiple viewports with different settings for Scene Lights / Scene World, so it would be arbitrary.

Afraid we have to close this (but feel free to comment again if you'd have a way around this)
