I don't think that's it. This behavior is consistent between several retries. The clients are running on my main pc while the server isn't doing anything but llama.cpp and sometimes RDP for convenience.
For good measure, I did another retry using the exact same prompts while the only thing running on the server was llama.cpp launched over ssh and zero GUI/graphics elements. The results were identical.
I guess I should try making a new ST profile to check if I have some old feature/plugin enabled that influences this somehow.
