phoc 0.12.0 needs Breaks against mesa (and potentially livglvnd0)
See https://gitlab.gnome.org/World/Phosh/phoc/-/issues/258
After installing sudo apt install -t octarine libegl-mesa0 libgl1-mesa-dri libegl1-mesa-dev libglx-mesa0 mesa-va-drivers mesa-vdpau-drivers mesa-vulkan-drivers libglapi-mesa libgbm1 (not sure if all of these are necessary, I just upgraded every package with mesa in its name that were already installed) phoc 0.12.0 is happy again.
phoc only (if I understood correctly) Breaks against libglvnd0 for additional outputs to be correctly recognized.
