Actually it has changed back to normal now.. Thanks!
Rascal78 that's an ad window, and you can't do anything about that. Roku puts ads there all the time, and you have no control over what will appear there. It's the same on my Android TV devices, with ads across the top part of the screen that I can't control. They only control you have is the custom themes that Roku pushes out occasionally and when they add a menu item for something new (like they did for Spiderwick). Those you can disable.
The lower-left ad depends on the theme. I use the Nebula theme and never have that one.
The right one is a promo ad, so you can't hide it. With regular ads, you can highlight the ad and hit the asterisk key and choose to hide it. It will be replaced with a different one.
