Simple solution: isolate, by running 1 X server per client (or set of clients if you want gimp and krita in the same sandbox)

Is there any tutorials/examples of how to do this?

Apologies for not answering your question directly, but I'm pretty sure this is what XWayland does to allow for compatibility of X apps ontop of wayland.
