              Took me a while to isolate this issue but eventually found that there where rectangles being drawn with an alpha value of zero. In the content parser we had a special condition where we changed the compositing rule from DST_OUT to SRC_OUT if the alpha value was zero. I can think of a good reason as to why this would be the case and can only assume that this was added to try and address some partial support for transparency groups.

              A user on the forums, http://jforum.icesoft.org/JForum/posts/list/0/20803.page also came to the same conclusion which is interesting. I'll make the change the let QA decide if its valid.
