Strange I had the slightly faded bathroom mirrior persist for quite a few screens.
But while ignoring it I didn't notice if it ever disapeared after that.
Just know that on mine at some point it turned into the faint image of a whisky bottle.
And then the update ended kinda like playing a game with a water mark in the images weired.
Just sayin.
This is the first I heard of that particular issue. Nobody else has mentioned it. I added it to my production notes though and when I circle around back to this later, I'll look into more.
