When I switched to using a QCCompositionLayer the particle system starts rendering incorrectly. In particular it looks like the blending modes are messed up. Here is the "correct" appearance:

And here is the bad:

As you can see the note images in the particle system are no longer colored but appear to be a washed out yellowish color. The blending mode for the particle system is "add" but changing it does not make the view and the QCCompositionLayer match appearance.
I have tried making the QCCompositionLayer opaque and giving it a solid background color. The composition has an opaque gradient billboard as a background. Nothing has helped so far.
Searching around I have not found anybody else reporting this issue but then there does not appear to be many people talking about QCCompositionLayer in general.
I would be happy to provide my composition but since the issue only manifests itself in a QCCompositionLayer I would have to make an example program to show the issue.
Hopefully someone will have encountered this and found a solution and say you need to set the fliberdyjibbet attribute to "whuzzle" and it will be fixed. :) I apologize if I have missed something obvious or not provided some crucial bit on information. Thanks.
