Shadow Light Bleeding

Is there anyway to prevent the light bleeding from realtime shadows? This happens alot with intersecting things that dont have their vertices welded together.

Give walls a real depth instead of just a plane then it won’t be visible.

Its not exactly a bleed but a precision limit.
Not using soft shadows reduces it but is likely not desireable and in the end you shoul never have paper walls anyway, there are other problems with non-walls (0 depth walls) as 0 just is no favorable width of an object thats meant to block anything
