It heappens with both mja bulk trailers (image). The truck in front does not seem to be important.
May it be they would be shifted one or two pixels to the front - but it is all I see - and no any terrible bug.
No Vaclav, the problem are the white pixels of the front part of the trailer. I knew of it and probably reported, but I'll check it again. Thanks uci :)
Than I am sorry because I thought that those bright pixels should highlight something.
Fixed (again after alpha release).
