We are having a problem with the angular gauge widget in IE. Sometimes  it is rendered incorrectly and all we see is a small gray cube in the  top left corner. 
  
It looks like the size of the chart is 1x1cm. If we refresh the browser  then it shows correctly. Sometimes even on the first time it looks fine.   
  
As I said, this only happens on IE. Firefox and Chrome are fine. 
  
Any suggestions?
