temporary displays content outside of container
On two customers machines with Windows 7 and Firefox 26 happens following: At the webpage I have a div container which display the several different content, depending on the menu item choosed. Only with 2 contents there is a wrong display: Below the container there is a single line of content text which should not be visible (outside of container). This line disappears after some seconds.
I can't reproduce this on Mac, on Windows XP and Windows7, where the Windows machines are running in VMware. Neither a friend of mine can reproduce this. On the clients machine the wrong display is not shown on IE. This machine has a ATI Mobility Radeon HD3400 graphics card.
You can test this behavior at this 2 urls:

You can see the wrong line at this screenshot: http://gondomir.de/daten/steracfehler.jpg
On all other menu items the wrong display doesn't appear. The page is valid XHTML 1.0 strict. I also can't see a significant difference between the pages which works and which not. The pages makes heavy use of JavaScript.

Edit: This error does not show, if you scroll in the window and reload the page.
Did you try disabling hardware acceleration?
Try to disable hardware acceleration in Firefox (you need to close and restart Firefox).

Hi! I got the response from the customer. Disable hardware acceleration fixed this issue. As I can not reproduce this on my machines, is there a hint which HTML/CSS/Javascript code may cause this error?
