Huge problem while rendering screenshot

Before on Version 4.0 I didn’t have this problem. I updated to the new (horrible licensing) 4.1 version.

I always use “clear” background because it’s a neutral background that I enjoy very much.

But now for some reason, when I render a screenshot, the background does something really weird :

This is what it’s supposed to look like :

Why does this happen in version 4.1 ? How can I have the background be displayed as it’s shown in enscape in real time ? What is going on ? I’ve never seen this problem before and I’ve been using Enscape since 2017.

Thank you for your response.

I found the problem, I had Alpa Channel activated.
