Sorry to hear your problems with CentOS Stream 9.   As you have 
discovered, it is too new for general use.  You are beta testing for  
Red Hat Enterprise Linux 9, which is not available yet.  If you want to 
continue to be a beta tester, report these problems to Red Hat.  For 
example, the fact that the mesa-libOSMesa package is missing.   Once 
RHEL 9 comes out, we will work on making a ChimeraX release for it.
