Issue with removing background on transparent image (v1 API)

Hi everyone,

We’re experiencing a strange behaviour when uploading an image on which the background has already been removed. The background is already full transparent, and the border of the subject are very crisp, so I’d expect that the result had no visible alteration. The source file is available at this link: https://test-cdn.thron.com/api/v1/content-delivery/shares/6epgi3/contents/b76d9f55-8fa4-4573-b25e-19cc38bffd2e/image/customer_provided-original?w=2731&h=4096

However, we’re receiving an output image with a couple of strange artifacts on the space between the trouser’s legs, and the edges of the legs themselves.

This is the call we’re performing:

curl --location 'https://sdk.photoroom.com/v1/segment' \
--header 'x-api-key: XXX' \
--form 'image_file=@"original.png"' \
--output "output.png"

Regards,
Leonardo

We received a second notification on another content with the same features (PNG with transparent background); the result is similar and has the same artifacts.

The result is as follows:
