That is the same animation, but it is also triggered if you have chosen a different wallpaper per virtual desktop. It animates the background change when switching desktops, and the animation feels like it lasts around 500ms. I wouldn't mind a quick animation but the default is too slow.

Sounds like the fade-in between images when you choose a folder with files to set one as wallpaper every 5/10/15 minutes
