Flashing content in Document

[LeoYang06]

Embedded PCLView control in Document, PCLView content keeps blinking. Its not clear if it is related to this.

<LayoutDocumentPaneGroup>
	<LayoutDocumentPane x:Name="LayoutDocumentPane">
		<LayoutDocument Title="Document 1"
                        ContentId="document1"
                        Description=""
                        IconSource="{nfo:FrontierImage About,
                        Brush=DodgerBlue}">
			<views:PCLView />
		</LayoutDocument>
	</LayoutDocumentPane>
</LayoutDocumentPaneGroup>

The code in PCLView is as follows, passing the Panel handle to C++ and drawing the content.

<WindowsFormsHost Grid.Row="1">
	<forms:Panel x:Name="renderContainer"
                 BackColor="#040508" />
</WindowsFormsHost>

Everything shows up fine outside of Docking.

Is this related to #85?

I cannot see the file.git，The problem may be caused by the compatibility of DX and user32 controls.I need a demo that can reproduce the problem

There is an idea to use WriteableBitmap as graphics cache，like the project of CefBrowser that chrome used in wpf

@LeoYang-Chuese Can you please attach a re-producable zip code container to this issue?

@Dirkster99 @LyonJack
The problem occurs after using the UserControl wrapper PCL, and does not occur without using the UserControl wrapper.

Project AvalonDock.Demo operates normally, and Project AvalonDock.UserControlDemo can reproduce the problem.
