Can see the time and date being added here I think:

end simultaneousHowever, it may definitely get broken by Apple, as you note.
I won't use it, myself, because I can't deal with wallpaper moving behind my work (I also can't listen to music, while I work. Maybe it's a "generational" thing). Also, I use a 49-inch ultrawide, so it might be vomit-inducing.
I remember some other utility that played wallpaper videos, but it wasn't anywhere near as nicely done.
And I wasn't even using video wallpapers at the time.
Just discovered I had no internet 3 days into the month as my ISP had cut me off. Had to dig deep and spend hours I'll never get back trying to find out where all the data was going.
Here's a thread I just found now that shows others having similar issues: https://www.reddit.com/r/MacOS/comments/1ii38g8/macbook_wall...
