It looked close to this:

I had it set as my background up until the big update (I believe the one to Manjaro 20). That was the update that caused a bunch of UI issues on Gnome especially with the dock. And I think it got rid of the background I had and actually deleted it even though I was actively using it.
Crazy part is, I’ve looked back through all the old versions of gnome and none of them have a background like this. Maybe I’m just imagining that it was part of Manjaro? Maybe I downloaded it somewhere else? Anyone remember seeing a wallpaper like this on Manjaro sometime in recent past?
