Removing volume scatter from the broken file seems to fix the smudging. Copying all objects into a new file (Blender Build 2019-05-23 14:37, hash: fd3f75a02c) with volume scatter also works fine.

Recorded the smudging issue happening today (version: 2.80 (sub 71), branch: master, commit date: 2019-05-23 16:13, hash: a3bc869038.

Not sure if this is related but switching one of the viewports to material killed the light in the rendered mode - the smudging started happening shortly after.

Edit - removing volume scatter stops the smudging but the lights still break, will move to another issue

Seems like Collection Instances + Volumetrics are causing the smudging:

Looks like it. Seems to be instances + volume then?
