I posted the details about what happened along with sample videos on the forums but it never got a response. Resolve doesn't offer email support for the free version and the paid version has no trial so I have no way to test if things would get fixed with the studio version.

I tested it on Debian (unstable channel at the time), but the same problem happens on Windows too. If I were to try Linux again it would involve setting up a dual boot and maybe trying Arch, or at this point Debian stable maybe (when I tried unstable it was before Buster was available).
