The black triangle below 6 is created when drawing via BBitmap::View::FillPolygon. It shouldn't be there (as evidenced when drawing directly to BView (grey screenshot)

    13I have 2 code paths to draw a BPolygon.  The first one draws directly from BView::Draw() (via FillPolygon) and works fine .  If I add the same BView to a BBitmap, then there is occassional corruption when drawing the BPolygon.  See screenshots.  The grey polygon is done directly via BView::Draw::FillPolygon.  The coloured polygon is drawn when added to bitmap (it creates a mask used for compositing).  Saving the BBitmap data also shows the corruption so it's not the compositing code path.
