You may have noticed that, lately, UHub pages bounce around a bit before finally settling down and letting you read them. It has something to do with the top of the page, where the site menu and the search box are. I've turned off the mobile, "hamburger" version of the toolbar for now, which has reduced, if not eliminated, the bouncing, until I can figure out what's going on. My apologies for this, but hopefully it'll reduce your vertigo.
