Closed

System Information
Windows 10, GeForce GTX 1080 Ti

Blender Version
Broken: 2.8 c750ebe113 (and any earlier version)

Short description of error
Denoising seems to produce artefacts around objects with light emitting materials. This bug report was requested by @LukasStockner following the AMA at the Blender Conference.
It's unclear to me whether the artefacts are caused by misconfiguration or if the denoiser handles the scene suboptimally.

I apologize in advance in case this doesn't work as expected due to my lack of knowledge about the denoiser and its settings.

Increasing the feature strength mostly eliminates the artefacts, but this does potentially impact other areas and one might lose details there, right? If the current result is the expected behavior, please close the task.
