The crop function doesn't work with ai generated PNG

[linopolo]

"I'm using WordPress 6.8.2. The bug occurs both on my live website and locally with XAMPP. I generated a PNG image with ChatGPT, uploaded it to the media library, and used the crop tool. I applied the crop and saved the result. However, when I insert the image into a page, it appears uncropped.
I Attach the image so you can test it

Hello @linopolo
Can you try to add the image, and then go to the right sidebar > Block > Resolution and Select Full Size or Thumbnail?

I'm not 100% sure, but it feels that the cropped Large size is not being generated correctly.

[linopolo]

Ok it works.
To run a more accurate test, I converted the generated image to JPG, then uploaded it to the library, cropped and inserted it into the page. The problem persists. On the other hand, a regular PNG taken from Google retains the cropping.

Can it be that the C2PA data is blocking the conversion?

Check your image on

​https://contentcredentials.org/verify

and you will see it has content credentials

[linopolo]

yes the image has C2PA data I updated also the complete exif of the image

Can you also upload the JPG you mentioned before?

I stripped the JUMBF data entirely from the original png:

Thank you for the support. So, at this point, what will happen? Will there be any changes to WordPress? Or should I just stick to the first suggestion you gave me?

Oh wait, my mistake. I did push the 'update' button instead of 'Save Edits'. I'm sorry.

I bet it's not a metadata problem. @linopolo try with another of those "AI-generated images", with different dimensions. Instead of 1024×1536, try with a square image 600x600, for example. I have a feeling that there coudl be an edge case bug.

[Presskopp]

The issue seems to be the generation of the 'large' size only, as you mentioned before.

[linopolo]

Ok, I generated by chatGPT a 600 x 600 image png. I converted it in jpg.
I Uploaded all two on the library, cropped both then inserted in a page and it works.
Now I upload the two images for yout test

Jpg 600 x600
