Yeah -- I think it's a known bug (though not sure if it's in the tracker).
The solution is probably to do something like the compound path rendering you (Phil) have experimented with, or, perhaps more easily, rendering without alpha to a temporary image buffer and then compositing it with alpha in a single step.

Any solution to this has to be to make them not overlap at all. This is an old problem, to be sure.Ben Root ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
