Hello @M66, welcome to the forum.
Is it a background pattern Messaging app you are referring to? If so you can remove it by going the conversation in question then clicking the 3 dots in the upper right corner. Then click Clear conversation wallpaper.
If this not what you are asking about please get back to me and elaborate what it is you need assistance with.
