The poster says MiniMax-H3 runs impressively in ComfyUI at first, but their next three text-to-video generations all show the same strange floating artifacts—colored spots, tokens, fruit-like shapes and leaves—across different prompts.
- Hardware used: RTX 4090 with 128 GB system RAM.
- One attached example shows a black cat video frame with bright floating overlay objects.
- The user is asking whether others have seen the same artifact pattern and whether it can be debugged.
