Hi there @Ivancamachovaladares!

Firstly, a big thank you for raising this issue. Every piece of feedback we receive helps us to make Umbraco better.

We really appreciate your patience while we wait for our team to have a look at this but we wanted to let you know that we see this and share with you the plan for what comes next.

• We'll assess whether this issue relates to something that has already been fixed in a later version of the release that it has been raised for.
• If it's a bug, is it related to a release that we are actively supporting or is it related to a release that's in the end-of-life or security-only phase?
• We'll replicate the issue to ensure that the problem is as described.
• We'll decide whether the behavior is an issue or if the behavior is intended.

We wish we could work with everyone directly and assess your issue immediately but we're in the fortunate position of having lots of contributions to work with and only a few humans who are able to do it. We are making progress though and in the meantime, we will keep you in the loop and let you know when we have any questions.

Thanks, from your friendly Umbraco GitHub bot 🤖 🙂

Hi @Ivancamachovaladares, thanks for the issue report.
I have tested this on 15.3.1 and 16.0.0-rc and cannot reproduce with the steps provided.

I wanted to ask you on which URL do you see the black background, is it in the Backoffice media library?

What about the website frontend?

What about the direct source URL of the image, i.e,. is the black background already present on the source image or applied later down the stream?
