Was doing this to me and once I removed the "filter:" line the bleeding went away. Plus I use PIE.

Bleeds:

Quick IE Shadow Fix:

fixBoxShadowBlur($('*'));

function fixBoxShadowBlur(jQueryObject){
if($.browser.msie && $.browser.version.substr(0, 1) == '9'){
    jQueryObject.each(function(){
        boxShadow = $(this).css('boxShadow');
        if(boxShadow != 'none'){
            var bsArr = boxShadow.split(' ');
            bsBlur = parseInt(bsArr[2]) || 0;
            bsBlurMeasureType = bsArr[2].substr(("" + bsBlur).length);
            bsArr[2] = (bsBlur * 2) + bsBlurMeasureType;
            $(this).css('boxShadow', bsArr.join(' '));
        }
    });
}

}
