I am pretty sure that no RDP solution for any Linux desktop system uses graphics primitives. For that to happen, all the toolkits would have to implement some way of passing their scene graph and their primitives to the compositor and the compositor would have to know what to do with that info.

RDP also supports plain framebuffers and that's what we use.

Anyhow, with the advent of specialised hardware for video encoding, passing framebuffers isn't necessarily such a bad option. You just have to make sure that the CPU doesn't touch the framebuffer before encoding and after decoding.
