I guess you should expand a bit on the exact setup you're doing here. Are the pipes working the same way on the DE2 than on DE1, ie does the pipe blending applies before the alpha blending, and therefore you need to make sure that there's not two planes with alpha going to the same pipe? Also, you seem to use the pipe and channels indifferently now, why is that? Thanks!
