I find this a lot with HTML guys I work with. They add a few px of padding to the top of something to get it vertically centered on Chrome and then it's broken on IE. Then I tell them to fix IE and then it's broken on Chrome. Then it's two more hours of screwing around until they get it right. Then I show it to them on a notebook with a different DPI setting...
