If that is the case the normal way of doing that is using a double (or triple,
or n-ple) buffer instead of copying. Given that a render will clear the
contents
anyway, you can get by without copying and avoiding the performance hit from
it.
Just use different TextureChunks and replace the one attached to the FBO.
