Debugging Qwen Image Outpainting Errors

Fine-Run992 · reddit · 2026-07-17

The author encountered an error while performing outpainting with **Qwen Image Edit 2511** and wants to determine if the issue stems from mixing quantization and VAE components. Their environment and configuration include: - ComfyUI 0.28.0 - `Comfy-Org-qwen_image_edit_2511_int8_convrot.safetensors` - `dummy9996-Qwen2.5-VL-7B-Instruct-abliterated_int8.safetensors` - `Comfy-Org-qwen_image_vae.safetensors` They note that this setup works fine for simple text-to-image generation but fails during outpainting. They are asking whether mixing `int8_convrot`, int8, and BF16/FP16 VAE might be the root cause.
