Event Timeline

Jacques Lucke (JacquesLucke) triaged this task as Confirmed, Medium priority.

Same effect with volume scatter connected to volume socket in world output in eevee

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: rBfd3f75a02cf9) 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: a3bc8690387b.

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:

I assume this is the same issue? T65004

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

Yeah. happening everywhere, like in this demo scene:

Maybe this issue should be high priority???
