Yes, XDG_RUNTIME_DIR is problematic, but as "su -" doesn't work in GNU Screen (it yields major display issues), I presume that some environment variables (terminal related?) are still useful.
I just have tried it. "su -" preserves TERM=screen.xterm-256color. Behavior is different from pure xterm-256color, but I have no guess what you may consider as major display issues. E.g. vim is even able to determine if background is dark or light and to adjust color scheme accordingly.
