Webkit box shadow causes massive performance issues

Question

when loading pages within the webkit container, those that have webkit box shadow end up scrolling really slow, and some pages end up more erratic than others.
Here's a few pages:
http://thenextweb.com (slow)
http://ign.com (almost can't browse)
http://shoemoney.com (shuts down the air app)
Is there someway to disable html5/css3 features?
Also, scrolling works for these sites on the Mac.
Thank you for your help.

Hello,
I'm sorry for the delay, Adobe US just got back from our winter shut down.  I took a look at the website's you listed but unfortunately wasn't able to reproduce the problem on either Mac or Win using the following code:
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
                            xmlns:s="library://ns.adobe.com/flex/spark"
                            xmlns:mx="library://ns.adobe.com/flex/mx"
                            creationComplete="init()">
     <fx:Declarations>
          <!-- Place non-visual elements (e.g., services, value objects) here -->
     </fx:Declarations>
     <fx:Script>
          <![CDATA[
               private function btn_click(evt:Event):void {
                    html.location = textInput.text;
               private function init():void
                    html.location = textInput.text;
               private function onLocationChange(evt:Event):void
                    trace(html.location);
          ]]>
     </fx:Script>
     <mx:VBox width="100%" height="100%">
          <mx:ApplicationControlBar dock="true" width="100%">
               <mx:Form styleName="plain"
                          defaultButton="{btn}"
                          width="100%">
                    <mx:FormItem label="location:"
                          direction="horizontal"
                                    width="100%">
                         <mx:TextInput id="textInput"
                                          text="http://www.adobe.com/"
                                          width="100%" />
                         <mx:Button id="btn"
                                      label="Go"
                                      click="btn_click(event);" />
                    </mx:FormItem>
               </mx:Form>
          </mx:ApplicationControlBar>
          <mx:HTML id="html"
                     width="100%"
                     height="100%"
                     locationChange="onLocationChange(event)"
                     verticalScrollPolicy="auto"/>
     </mx:VBox>
</s:WindowedApplication>
Do you have any sample code that would illustrate the problem you're seeing?  Is there a particular OS I should try?  Anything else you might think is relavent?
Thanks,
Chris
