We've also seen this fail on one screen size/resolution combination but pass on another combination. We're investigating what our test criteria should be. I asked the community (via Facebook and Twitter) what screen sizes, resolutions and zoom levels people are using. The most interesting insight that I hadn't realized before is that several respondents use a system zoom coupled with a browser zoom.
