Toggle Flickers in IE8 for "slow" speed

[curious]

In IE8, when toggling to hide the element, the background that was previously there flickers at the end of the slide if the speed is not set to "fast". If the speed is set to "fast" it does not flicker and looks perfect as intended. This flickering does not happen in Firefox.

I am a newbie and going through the tutorial "Tutorials:Getting Started with jQuery" and using the jQuery Starterkit. The CSS compatibility is "BackCompat". Here are some examples of what works and what does not work:

This flickers (default): $(document).ready(function() {

$('#faq').find('dd').hide().end().find('dt').click(function() {

$(this).next().slideToggle();

});

});

This flickers ("slow"): $(document).ready(function() {

$('#faq').find('dd').hide().end().find('dt').click(function() {

$(this).next().slideToggle("slow");

});

});

This works perfectly without any flicker ("fast"): $(document).ready(function() {

$('#faq').find('dd').hide().end().find('dt').click(function() {

$(this).next().slideToggle("fast");

});

});
