The spinning circle left of Welcome after typing password is invisible. Still a space for it, it's just invisible. Anyone know how to correct it? It came back once but gone again, lol. I tried changing lock screen wallpaper and other lock screen settings. I was trying to fix a very annoying PC freeze when using web browser. (turned out to be Avast and had to repair it.) Now, this is the only problem left. It's very small but really weird.
