A couple of weeks ago, within IE8, most video and certain other objects like gifs and hypertext flash with horizontal bars flashing across the object. Some of this occurs while a page is downloading (gifs and hypertext) and then stops when completed while certain videos flash when played while others do not flash at all. Also, when using the scroll bar, the entire screen flashes in the same way, with random horizontal bars.
Anyone have any idea why?

Unbelievable. It seems quality in
