I'm no expert but the clearance looks too small for me - don't really know how stiff this frameset is but I think that it could very well flex enough to scrape the chainstay when you apply more force through the cranks. Did you measure the chainline or it just "looks" right? I would try swapping the BB for a longer one if possible.
