Lockscreen wallpaper just started appearing

[kombatkarl]

On my LG G4, yesterday a new lockscreen just started to appear. If I tap the memory icon it acts like it is doing a sweep of the memory. Once I "Swipe To Unlock" I am taken to my normal lock screen to do the pattern I have set up. Any ideas where this came from? It's very annoying.

Does it persist in Safe Mode?

No, it does not.

In that case, it's caused by a third-party app.
