I checked the support ticket that you send us and will also paste the answer here in case anyone else is interested in it:
...Regarding the problem with our demo site, we are not sure what may be the cause. Obviously all of the scripts/styles are loaded correctly. We are also using the same resolution (1920x1200).
We have tested this page on different machines with IE11 and have tried with choosing different modes of the browser, but we are not able to reproduce it. Could you please check if you observe the same issue on other machines with IE11. If the problem persist, could you please try with restoring the advanced settings of IE from Internet Options -> Advanced.
We will be waiting for your reply...
