The same scene on Mac OS shows a clear black line, but no black line on windows.

The dot is visible in both places.

@mvaligursky Martin, I think you got Mac? Do you see the issue as well?

I remember that black dot issue on my Windows laptop as well. I didn’t think I created a report of it as I was quite new to PlayCanvas.

We seem to have an issue on this already. Seems to only happen on sphere lights.

The issue is with the area light and glossiness property. If I keep the glossiness value above 80%, it starts to show.

Correct, the issue mentions that a high glossiness is needed.
