What does 13583 1x1 pixels mean? My iPad randomly takes me to a screen with this.

It's an ad collection cookie. Here's a link that opts out and makes it go away. At least it seems to have worked. I was getting the blank web site while playing a game and it has not happened since. Good luck..

Sorry....seems it didn't solve the problem.... Took a while, but came back.. Maybe someone else will solve it...

This is happening to me too, and it's getting really annoying. I'm thinking of permanently deleting app if it can't be stopped.

That's what I did... It was a solitaire ap and once gone,so was the problem..

So how did you figure out which app it was? This just started happening to me again today on a totally different (new) mac. 😕
