A long time later I think I now know what's going on.............
I think it's Nissan bokeh that causes the effect....the spiting of OOF subjects making double edges , given the right distance apart these double edges combined with the double edges of other grasses etc. (by chance). and produce interference patterns that mask detail by adding and subtracting "clutter" in localized areas of the image.
It never happens on flat areas even when there is much detail!
