X with line at top of screen
There's an X with a line at the top of the screen. Clicking the X produces a dialog asking if I want to leave the page. What is this and how do I stop it from appearing?
Something about how the page looks makes me feel like I'm seeing a page meant for mobile even though I'm on desktop Chrome.
I see it being a progress bar now, but I don't recall seeing it change as I answered questions when I posted the question. It's possible I found it so bad looking in conjunction with the new terrible mobile optimized content senselessly displayed on a desktop page, and going to an ad at the bottom of the page first then jumping to the top of the page, I didn't even try to answer a question. I don't remember. Like many other sites, multiple device characteristics and fluid-dynamic-adaptive layout is resulting pages that are barely tolerable where they work best and much worse everywhere else.
