The problem is, that all graphic sliders are set by default at 2/3 of maxium. It lead to many objects missing (not displayed) in coalition space and I had at first no idea what is going on. I thought first that it is LOD issue (some objects visible only on very short distance, some stations not visible at all, coalition trade lanes invisible), but then I got idea look settings and sliders were not maxed. I maxed them all and game looks how it should again ...
I played before for few hours in Sirius space and there was all visible, so it was quite a surprise when I switched to my char in coalition space and saw missing graphic ...
