Short description of error
Local collections in viewports don't update when an object is wither created or moved into one currently (in)active in a 3D view.
When you create or move an object into a collection that is currently visible or hidden inside one or more 3D views then the visibility isn't updated correctly unless the eye icon for all affected collections has been activated.

Here is a video to demonstrate this more clearly:

Uncheck the collection "Exclude from view layer" box, and update occurs.

I'm a student developer trying to contribute to blender, and this doesn't seem to hard an issue. Could I try this out? Any pointers as to which parts of the code base I must focus on? I was able to reproduce this issue on 2.90, and it looks simpler to fix than most stuff in the quick hacks.

Hi @actuday, from a quick test here I noticed that forcing the viewport to re-calculate the objects visibility fix it (e.g., add a new collection and toggle its visibility, or toggle the local collection button). So see what is happening when either of these operations happen.

There is a chance that these operations are calling an overall update of the visibility calculation, which is less ideal. In that case compare to what the move to collection operator is doing. Maybe it is already calling for an update, but it is missing the viewports? Maybe it is being smart about updating the object visibility (most likely scenario) but it is messing something up.

Relevant information: This bug also affects moving an object into a locally hidden collection from the 'Move to collection Menu' (shortcut - M).
