This is why Christian and I have invested so much effort into the CI system for Debian. There needs to be a clear accounting of what works and what doesn't for every library on every architecture.
It's too late to edit, but I should add that the RX 6600 XT is not officially supported by the upstream ROCm project. It's not clear to me that the experience would be better on any other distro. That's where having public test logs would be valuable.
IIRC, nothing below the 6800 is supported by ROCm... so the lion's share of their installed base of the 6000 series is excluded from 'official' support. nVidia's compute drivers support all of their devices and have across multiple generations, AMD's support only the low volume devices and drop support for older generations seemingly almost as fast as they are released.
