I want to show accurate borders of provinces in my map, but there is a "small" problem. When land or river province borders with PTI, PTI cover hers neighbours for about 20 pixels. (And you cant't see shading layer covered by PTI effect). There is no such a problem with sea provinces.
Can I modify the way how PTI cover provinces? Or only solution is to enlarge ids layer? (like in the picture below)?
As you see my solution (enlarge IDs) is ugly... (But still better than PTI's blotch in place of borders). I want smaller PTI effect... (not 20 pixels but 2-3 max) Is it possible?
