Changing modules with url property of moduleLoader causes buttonBarButtons transition to flicker?

Question

http://filip.nedyalkov.net/moduleLoaderTesting1/ - source code view enabled - the mxml file is testing2
So as topic says, I am using moduleLoader to load 2 different modules with the use of buttonBar which has custom skin for the mid button which I use for all 3 buttons in it. In that skin there is a transition defined for up, over and selected states, which is fairly simple.
In order for the problem to be seen, I use another default buttonBar under it. Clicking on it's buttons will change the selectedIndex of the custom button bar so he has the same selected button as the bottom buttonBar.
So if you click on "no module" you will see that the transition is fluent, the icon goes a little darker and it's fine. But if you click to load module1 or module2, there is flickering with the icons that get in the selected state which kinda matches when the new module child pops up.
So my question is simple - how do I fix this?
Any suggestions are welcome. Feel free to download the code and test yourself.

Hi, thanks for the reply.
If you checked my example source code you would see that both of my modules are alike just the rectangle fill has different color:
<?xml version="1.0" encoding="utf-8"?>
<mx:Module xmlns:fx="http://ns.adobe.com/mxml/2009"
           xmlns:s="library://ns.adobe.com/flex/spark"
           xmlns:mx="library://ns.adobe.com/flex/mx"
            width="100%" height="100%">
    <s:Group width="100%" height="100%">
        <s:Rect width="100%" height="100%">
            <s:fill>
                <s:SolidColor color="0x000000" />
            </s:fill>
        </s:Rect>
    </s:Group>
</mx:Module>
How more lightweight the modules can be...
I did some more testing and there is no flickering when the module is unloaded only when loaded. And also if I set a timer to load the module after the transition is over there's no flickering. Also there is no flickering for texts and also there is less but still sometimes flickering if the transition target is not rect but group. And also if I set the transition to be not 200 ms as in my example but 1000 ms or more then there is no flickering again which doesn't make any sense to be, cause the flickering in a slower animation should be way more obvious that in a very fast one but it is in the countrary.. no flickering at all. Any ideas ?
So to fix the problem I have 2 options:
1) setting at least 1000 ms transition where I don't have flickering
2) use a timer for shorter transitions and load the module after it's ended
But this "hacking" doesn't seem very appealing to me so that's why I am asking here if this is a bug or what ?
