Does snapcompact's pixel-font context compression work with self-hosted VLMs?

A Reddit user asks whether oh-my-pi's snapcompact works with self-hosted vision models. The scheme replaces normal LLM summarization by rendering the conversation into dense pixel-font PNG frames that a vision model reads back — no LLM call, no API key, fully deterministic.
For cloud models the pitch is saving billed vision tokens, but the poster self-hosts DeepSeek-V4-Flash-Vision-Exp on 2× RTX Pro 6000, so there is no per-token billing to save and render compute is cheap. The real question is whether a local VLM can read those frames accurately. All shape tuning and recall evals were done on Claude, Gemini, GPT, Kimi and GLM, with no local-model benchmark available; the maintainer also flags fidelity risk for code, tables, Unicode and dense terminal output — essentially a whole coding transcript. The poster asks for anyone with hands-on local VLM experience with snapcompact.
