I have a (rather different!) application that’s released as a Flatpak, and GPU acceleration is CUDA-only there, too. It supports ROCm when compiled locally, but ROCm just can’t work through the sandbox at this point, unfortunately. Not for lack of trying.
If you have an example of a Flatpak where it does work, I’d love to see their manifest so I can learn from it.
Fedora KDE is not deb based, but dnf is better than apt anyway fight me
