Visual bug with freeform Light2D overlapping itself

As you can see in the second image, the bounds of the light is intersecting itself. I’ve tried using AlphaBlendOnOverlap but that just reduces the effect slightly rather than fixing it.

I can only get this if I don’t use tight corners convex corners, which unfortunately I intend to use a lot of.

did you ever happen to find a solution to this?
