[enranime]

is this intend? when generated image using canny model it's will always leave white line (the line that control net draw in canvas)

~~Are you using images that have a black background and white lines? Canny model requires a white background and black line image as input (currently if preprocessor is none).~~

Not related, works fine on my end. Seems like a bug.
