Alright, before I go to bed, I found the following line in src/_backend_agg.cpp at line 709 (in draw_markers()) makes all the difference:
set_clipbox(gc.cliprect, rendererBase); Commenting out this line fixes my problem. I'm not sure why it's a problem, (maybe a missing restore to previous state somewhere?). I'll look into this tomorrow, but it would probably be a lot easier with someone familiar with the code.
