Has anyone else noticed that when there's not enough data to fill a mythweb page that the bottom of the page will be white? The white goes away (ie, becomes the background color) when the window is refreshed by switching tabs or opening another app over the white space and then closing/minimizing it. Also selecting a drop-down menu will usually immediately clear the white.

This is happening to me on Firefox 1.5.0.3 under Linux and Windows. I think it also happens on my wife's Mac Safari browser but can't be sure.

Yep. Seen that too with certain browsers. Firefox seems guilty of this, Galeon generally seems OK.
