artifacts in results

[vietpho]

Hi, thank you for your amazing work.
I ran your model using your pre-trained model, Afifi.pth. However, I am encountering some strange artifacts in the generated images. Due to privacy concerns, I can only show you a specific part of the image. However, I can provide more details about the image itself. The remaining portions of the image are filled with white, and there is a very small object of skin color present.
Do you have any idea why I'm experiencing these artifacts?
Thank you.
