MiniMax H3 Workflow Bug: Prompt Leakage and GPU Fans Spiking to 100%
gerentedesuruba · reddit · 2026-08-11
A user reports severe bugs while running MiniMax H3 in ComfyUI using a vanilla I2V workflow. Symptoms include:
- Prompt Leakage: Backgrounds and prompts from previous jobs bleed into completely new generations.
- Parameter Locking: Node settings get stuck in memory, ignoring changes even after restarting ComfyUI, requiring a full PC reboot.
- Hardware Anomaly: GPU fans ramp up to 100% for a few seconds during specific inference steps (e.g., step 1 or 17 out of 20).
