Blurry mouse-over popup previews in the store?

As titled. When I mouse over say, the Assassin's Creed Odyssey box that only initially shows the title card, platform, and price, there's a popup that shows the name in text along with the tags, reviews, and the store video.

That popup is blurry. I don't know how else to describe it. It's like it's just out of focus, and that wasn't happening yesterday.
