Description

Hi,
first, thanks for providing this awesome software!

One of the last updates broke the remove backround extension in the Extras tab. At least for me.
That one: https://github.com/AUTOMATIC1111/stable-diffusion-webui-rembg
It still removes the backround but its no alpha chanel anymore but just black, which is unusable.

I reverted back severall versions but only the one from before flux got it working again.

Steps to reproduce:

  1. put an image in the extras tab and enable remove backround.

It would be great if this could be fixed. I dont know if this can be fixed by the Forge team or the Remb Team.

Cheers

Research direction

Start by reproducing the issue in the Extras tab with the remove background extension linked in the report, checking whether the output is black instead of an alpha channel. Compare the behavior with the version from before Flux support was added and determine whether the fix belongs in Forge or the rembg extension. Done means background removal produces a usable alpha channel again.
