Why do I get a black background while loading some pages in IE9 and Safari? It seems to go away after the page finishes loading, but it seems to be loading a transparent.png in the background or something and there is a black background underneath of them, while only temporary it's rather annoying to watch during page load. I can guarantee you that the background color #000 is not in the CSS either. Sometimes the black "pre-load" will even stick halfway or all the way down the page too.
Has anybody else noticed this as well or is it just on my end?
