I think this may not be a gnome-shell issue at all. I installed appimagelauncher [1] some time ago and if I disable the daemon and reboot then it seems the memory leak is no more. At least I think that is the case, I need to do some more testing but thought I should report back immediately so that no-one wastes any more time on it.
I will follow up when I have reached a firm conclusion.
