problem is there when you launch steam like so: "Exec=/usr/bin/steam %U"

problem is not there when you launch steam as so: "Exec=env STEAM_RUNTIME=1 steam %U"

Running without the Steam runtime enabled can result in some things not behaving as they should. Is your distribution disabling it as part of their Steam package?

we have two launchers because we are using arch linux and some games just wont run correctly with your packaged libs in /home/anex/.local/share/Steam so in hence provide 2 launchers

Do you know what these problems are exactly? If they're related to Mesa C++ dependencies we're working on addressing that upstream, so hopefully in the future everyone can consistently run with the runtime enabled.

UPDATE: Preliminary package done: https://aur.archlinux.org/packages/steam-native/

The problem

Steam uses its own steam runtime based on Ubuntu LTS libraries - these are really getting out of date and can cause issues with rolling releases like Arch/Manjaro as the libraries are getting too old for compatibility.

Why is it important?

There have already been 2 issues whose fix was to remove libraries from the steam runtime - that's only a temporary solution, and while adequate for the Arch Way, it's not really acceptable in a distribution like Manjaro.

The solution

Make a new package (actually meta-package), installed by default in the Manjaro editions that have Steam preinstalled, called steam-native, which sources the required dependencies and, adds the libudev.so.0 symlink in the post-install/post-update script adds STEAM_RUNTIME=0 to /etc/environment, and removes the variable in the post-remove script. It would include steam in the dependencies.
