thanks, I will try.
I saw these effects in the austria map.
The effect of the --transparent option is only a change in the number of 
shapes. This means also a change in the number of sub divisions and
how different parts of a road are distributed to these sub divisions.
So, --transparent doesn't directly cause a problem.
