Issue description
When putting a lot of PointLight2Ds in an occluded room, with walls in the middle, choosing Mix blend mode, and enabling shadows for occluder to work, zooming in shows weird black lines:
Changing their shadow filter from none to average shows the artifacts more clearly:
Changing shadow filter smooth doesn't help...
Changing shadow filter color from "black" transparent to "white" transparent seems to ease the effect..
However you can still see the lines there:
Change shadow filter to average from none and you'll see clearly that the artifacts are still there:
Steps to reproduce
Place a lot of PointLight2Ds with Radial texture, Blend mode set to Mix and Shadow enabled in an encapsulated room with occluded walls, and two pillars on the center.
