# steam-runtime is a somewhat a mess bundled with old libraries
# due to this reason, system native graphic drivers may not load
#
# if we remove some bundled libs and preload some system libs
# system native graphic drivers will be able to load
#
# however we must do this everytime when we launch steam, because
# steam-runtime is being fixed right away by steam client
