'Flashing' RadPaneGroups

[Matthew]

I'm using prism in combination with RadDocking and am generally happy with the results so far. The region adapter blog you guys presented helped a lot. Still i have one gripe, below is my 'Shell' xaml. When the (silverlight) app first starts my RadPaneGroups, which are regions and initially empty, show (flash) for a split second before being loaded with region content (which shows them again) from my ModuleInit.

Has anyone seen this type of behavior before? Any solutions?

<telerik:RadDocking x:Name="layoutRadDocking">
    <telerik:RadDocking.DocumentHost>
        <telerik:RadSplitContainer x:Name="centerRadSplitContainer">
            <telerik:RadPaneGroup x:Name="centerRadPaneGroup" prism:RegionManager.RegionName="centerPaneRegion" />
        </telerik:RadSplitContainer>
    </telerik:RadDocking.DocumentHost>
    <telerik:RadSplitContainer x:Name="leftRadSplitContainer" InitialPosition="DockedLeft">
        <telerik:RadPaneGroup x:Name="leftRadPaneGroup" prism:RegionManager.RegionName="leftPaneRegion" />
    </telerik:RadSplitContainer>
    <telerik:RadSplitContainer x:Name="rightRadSplitContainer" InitialPosition="DockedRight">
        <telerik:RadPaneGroup x:Name="rightRadPaneGroup" prism:RegionManager.RegionName="rightPaneRegion" />
    </telerik:RadSplitContainer>
    <telerik:RadSplitContainer x:Name="bottomRadSplitContainer" InitialPosition="DockedBottom">
        <telerik:RadPaneGroup x:Name="bottomRadPaneGroup" prism:RegionManager.RegionName="bottomPaneRegion" />
    </telerik:RadSplitContainer>
</telerik:RadDocking>

Hello Paul,

The issue has been fixed in the Q2 2012 SP1 (2012.2.0725) release of RadControls. Could you please upgrade to that version or newer one and give it a try?
