How can i clear the cache or viusalize buffer of globedisplay in c#

When i create a polygon element on the Globe control and give it to rasterize property using IGlobeGraphicsElementProperties it works properly. However , when changing the position of the element by using updateElement() method, the old texture (contents of the previous screen for the element) is still shown on the screen (it is not refreshed). Is there a way to update rasterize polygon element or is there a way to clear the buffer/cache wherever it is stored.I guess IGraphicContainer and visual buffer are working asynchronizely because when i debug the code in graphicsContainer element property seen as it wanted . But i cannot find where the buffer/cache is stored in globedisplay. Same problem occurs when i want to delete the element although i delete the element it is seen on the screen.IGraphicContainer delete element does not work properly when a polygon element has rasterize property.
But when IGraphicContainer DeleteAllElements() method is called it deletes all element and works fine. My assumption is DeleteAllElements() method clears the buffer/cache in a way but how ?Please help me. Any help will be appreciated. Here is the screenshots.


In figure 1 original element is seen. In figure 2 i tried to move element and update it. On the screen the updated elemnt is seen with some part of the previous elemnt property .

IGraphicsContainer graphicsContainer3D = m_globeGraphicsLayer as IGraphicsContainer;

}
points[0].PutCoords(x_old, 39.5);
points[0].Z = 100000;

points[1].PutCoords(x_old + 1.5, 40.0);
points[1].Z = 50000;
