Describe the bug
I'm using the image streaming feature in my Gradio project. However, this feature appears to have stopped working since [email protected].
Previously, I enabled image streaming by setting streaming=True on the gr.Image component. This worked as expected in [email protected], where the right output image would update in real-time as the left input image changed in the example.
Starting from [email protected], however, setting streaming=True seems to have no effect. The output image no longer updates in sync with the input image. This behavior is the same whether streaming=True is set or not.

with gr.Column():

input_img.stream(lambda s: s, input_img, output_img, time_limit=15, stream_every=0.1, concurrency_limit=30)
