Created attachment 711524 [details] command line output of the steam client prior to the crash I made a test package with the runtime-fix removed: https://build.opensuse.org/package/show/home:Mailaender:branches:games:tools/steam and it indeed crashes after login on a Thinkpad X230 on Tumbleweed. Already tried steam --reset and steam STEAM_RUNTIME_PREFER_HOST_LIBRARIES=0 as well as steam STEAM_RUNTIME_PREFER_HOST_LIBRARIES=1 but nothing seems to help. Not sure how to debug this.
