Yes. It was fixed by putting black background on the colormap and deleting .kra files from the map folder (.kra is extension of Krita, my image editor). Looks like when I put black background first time, I didn't it properly.

Alright, i solved this problem myself

While creating new map, I encountered with error: game couldn't read my colormap. Everything in that colormap looks fine. I attached that colormap to this post.

Alright, there is an updated map, with most of downsides fixed. I left 3 blur variants and original map, 3rd should work best of those. And, even with using a mask on 3rd variant, I still have borders slightly affected somehow, so you can see some of parts of road artificially modified. And, as long as I played (rather, re-completed) this game more, I have more questions/suggestions: Add "skipsaves" option into option menu. Does wheel damage increases on offroad terrain? Not sure if its just my PC,...

Onsemeliot, thanks for feedback on my map! I will fix its downsides you just listed as I will back home (I am not at home now). And, as I read through level making guide, I haven't got why should "blurfilter" be matrix with diamond-shaped positioned numbers.
