The Gemma-4-12B encoder and the diffusion model can't share 14GB of iGPU memory, so ComfyUI runs the encoder on CPU and every new prompt costs 20 minutes before the first frame. Splitting the encode into stable-diffusion.cpp fixes that, once you find the model stage it silently skips.

Running LTX video generation on a Radeon 780M mini PC with no discrete GPU, through a VRAM ceiling, four LTX-2.5 loading bugs, a GGUF quant missing its architecture metadata, and a silently dropped boolean flag that turned coherent video into static noise.
