Back-lit slope self-shadow / shadow disappears when camera pans horizontally or zooms in.

[Jason.Zoe (JasonZ)]

I tried this but it didn’t work.

How to avoid disappearing / popping shadows when they are in the camera viewfield at short distances?

All over this scenes, shadows pop in and out in front of the camera at short distances (pay attention to the yellow building and to the building at the left): I have done everything listed in this topic: r.Shadow.FadeResolution r.Shadow.MinResolution r.Shadow.TexelsPerPixel r.Shadow.RadiusThreshold I also tried increasing Dynamic Shadow distance, but no effect.
