I have updated my note 10+

I have been always using a stock wallpaper amd a stock theme.

I have noticed , and this is a first day , that my background changes , its like stock wallpaper , but its like it kind moved or someting.

It stays like that , sort to say "moved" for a while , and than it returns on normal.

Or i can return it by my self , true wallpaper selection or true a deafult theme.

But has enyone expirienced this????
