With my new Moto, on a site like Google News, the site allows you to scroll either vertically or sideways. Sometimes when I'm scrolling vertically, it suddenly thinks I'm scrolling sideways, which I don't want. Have you had this problem? Try it on that site. It also sometimes happens in the Twitter app, in Search Results, which has two columns, for Top Tweets or All Tweets.
