I have a display failure while using menus with the minimize light theme.
You can try it yourself at
I have 7 items in the main menu. One of them has submenus (the about me item). If the page is fullscreen on my macbook, it works fine. But if I look at it from an iPad, the menu bar is split into two lines. And if I click on the "about me" menu item, the submenu is displayed over the second menu line and the text of it isn't readable any more.
You can reproduce this on notebook too. Just resize the width of the browser window until the Impressum item is below the About me menu and then move your mouse over the About me Menu item.
I am using iPad with iOS 7 and Safari 7.0.1. But I can reproduce it in latest Chrome for Mac too.
I hope you can fix this problem!
