I'm releasing a quick bugfix for the cpu throttle issue as is. If it turns out it isn't related to the memory leak we can address that as we find a way to reproduce it.
we prefer users use flatpak, distrobox and even appimage over layering fedora packages with rpm-ostree, but if you really need something at a system-level then use rpm-ostree as a substitute for dnf and reboot when you install the package. can also install COPR repos with this too
