Occasionally I run into limitations in the viewer (apart from bugs): a 
couple of thousand colors (and esp transparencies) in one form for instance 
can easily overflow some internal 'whatever' and then result in black 
images; it may have to do with some resource stack.

One characteristic of a form is that its mediabox is a cropbox as well 
(resulting in .5bp rounding errors because somehow internally the accuracy 
is pretty low). It may happen that during flattening (or even inclusion) 
this box is interpreted differently (or gets lost) thereby resulting in too 
much image. Over time one learns how to deal with that kind of side effects -)
