The big controversy over openSUSE Tumbleweed changing from apparmor to SELinux should be coming to an end soon. The devs have been working hard to get a fix pushed that will allow anyone installing wine, proton, lutris, etc to be able to use these game packages without issue. The new fix is a package that modifies SELinux remain in ‘strict’ mode while simultaneously allowing gaming to work. The package selinux-policy-targeted-gaming will now be installed as a dependency along with steam, wine, and lutris. As of writing this article only steam includes selinux-policy-targeted-gaming as a dependency. You can, however, install the package manually if needed with:
sudo zypper in selinux-policy-targeted-gaming
