Lighting Rays and Shadows

[[zcd]dARKtROOPER]

I am using a canted display VR HMD (8kX) and in the night I get strange behavior for lighting (and shadows)- like what has been posted here and there in the forum, but none seemed to fit exactly.  Depending on height these rays seem to grow and shrink and grow and shrink. I added a screenshot which shows what I mean, except for the dynamic changes to it. 

Also, the shadows re a bit strange/doubled as some other light, cloud, smoke issues (2D/3D, doubled and so on- but that’s another issue but it could be to the same cause, so I thought I mention it).
