Soft Shadows in Blender 2.90

When soft shadows are activated in Blender 2.90, a strong casting of rays appears, which cannot be controlled in any way.

is this a bug?

Those are not actually rays. Shadow maps are just that, maps. What you’re seeing are pixels being stretched along the wall. Increase your base shadow map resolution in the render panel under shadows. Also, shadows are no longer rendered with filtering anymore (the blurring affect). Instead the individual passes are rendered with crisp edges so the default resolution is far too low. All shadows are now rendered the same way so the global sampling settings (in the render panel) define how smooth the shadows will look.
