I've searched far and wide, and as far as I can tell no one else is having this problem. Whenever I try to set my background to a picture I've downloaded, it offers the crop options, but only offers the size/ratio for a single screen pane. When I crop and set it, I get a stationary background image that doesn't move at all when I flip from panel to panel in my desktop. I have no idea why it's not cropping my backgrounds to the wider ratio so there's a transition effect when swiped to a different pane. I'm using OpenHome, so I wouldn't be surprised if that had something to do with it... but I can't imagine why it's working the way it is. If I choose a background from the "wallpaper gallery" or through an app the background works normally. It's also not a resolution issue, since I've tried it with images I've used as hi-res wallpaper on a PC from interfacelift. Any ideas?
