If this is the OP then this is what my 'no fix' is referring to. Legacy gives me full (non broken) rendered lines.The yellow borders/coastlines do not fully render, but only partially render, leaving them fragmented.
I should probably made a separate post for the map layer render in general (sorry for that) but since they are both 'not working' for me since the 64bit version came out I thought I mention it cause they might be connected? If you want me to make a separate post i'll do that with some 1.5 vs 1.6 screens.
