But why do those fireflies have black outlines? Is this something with my PC/video player, or is it oversharpened to show the issue?

How many passes is that? Can you tell us more about this? It's hard to tell what happens here and what is the solution with so little information provided.

You use almost a year old version and touch settings that are clearly designated as debugging only and that they should not be touched, and then you complain something is not working.

But why did you even touch that setting in the first place, and did not even mention this, expecting that we will help you, buddy?
