when Using SDXL-control-lora with 6GB VRAM, "Ran out of memory"

I have tested SDXL in comfyui with RTX2060 6G，
when I use "sai_xl_canny_128lora.safetensors" or "sai_xl_depth_128lora.safetensors", it will show "Ran out of memory when regular VAE decoding, retrying with tiled VAE decoding."
but when I use "diffusers_xl_canny_small.safetensors" or "diffusers_xl_depth_small.safetensors", it works well.

when I use clip_vison, it works well too.

So the problem may come from comfyui's nodes. This maybe a bug.

Thanks for the great job and hope comfyui better.
