Solution to border disappear when dragging the scrollbar under IE _ Experience exchange

I usually use div plus border to define the edge, but sometimes I find that when I drag the scroll bar under IE, border will often disappear, and when you refresh, it will come out again.
This problem, I think for a long time and did not come up with any reason, so in some previous pages written in Div+css, this problem exists.
Today, this problem, it really affects the final result, where a hint: "think div plus a height can be solved." "
The following is a comparison chart before and after.

As for the cause of this problem, I think it should be IE bug. When you use Mozilla Firefox/opera you don't have this problem.
