@jvriesem that's not a problem, as you'd have to remove it anyway. The point of this exercise is to make Steam use the system versions of certain core libraries instead of replacing them with versions that don't work. (Why they would ship incompatible versions of standard libraries in the first place is beyond me) – tjollans Jul 24 at 10:25
You can create script with the following content to run it instead of steam:
#!/bin/bash
# Export so all child processes are affected as well
export LD_PRELOAD='/usr/$LIB/libstdc++.so.6'
export DISPLAY=:0
#export LIBGL_DEBUG=verbose
steam
LD_PRELOAD='/usr/$LIB/libstdc++.so.6' DISPLAY=:0 steam
