Hi,
I was putting many pins to a world map and over Rio de Janeiro, my city, there are too many pins represented by a PNG image with transparency. When the map starts those images overlap and a black rectangle appears. It disappears as we do zoom. I put the map (still under construction) here:
http://cartola.org/panoramas/Mapa/
and here is a screenshot with a red circle around what I mean.
Does anyone has already had this problem? Any solution / suggestion?
Thanks, Cartola.
