Created attachment 14520 [details] Screenshot showing issue in IE8 Since 1.23wmf12, the background of #mw-page-base (the top area, behind the tabs, defined in navigation.less) is rendered using linear-gradient only, and has no PNG fallback. This mean older browsers that do not support gradients, such as IE8, now show a plain grey background, and the tabs have a sharp white top edge. See attached screenshot
