I believe the tools like Resolve are built around VFX reference platform specs. I doubt anyone will standardise on the basis of a rolling distro where you can’t pin glibc version. https://vfxplatform.com
The flatpak runtime they would choose would have a fixed glibc version.
steamos is not a rolling release. yes, it’s built on arch, but they halt with snapshots and do testing and their own patches before they roll out updates.
