This thread is the continue problem of the thread below:
https://sharpgl.codeplex.com/discussions/441132

Now I can see two OpenGLControl in VS2010's XAML design window,
But the VS2010 becames slow, when I start the Task Manager,
VS2010 uses about 30%--40% CPU.
When I try to close the VS2010, VS2010 will crash.

But when I start VS2010 again, and DO NOT show the XAML design window which contains OpenGLControl, VS2010 is NOT slow.

I have tried several times, almost 100% occured.

Add some additional information.

My OS is Windows 8.

It looks like that after change the RenderContextType from "FBO" to "DIBSection",
After show the design view of the window that contains OpenGLControl, although VS2010 still uses 30% of the CPU,
But VS2010 will not crash after I try to exit VS2010.

Another question:
Why VS2010 still uses about 30% of the CPU even though I closed the design view of the window that contains OpenGLControl.
