Has anyone else besides me noticed the map flickering when the brightness or contrast is set to high while the map is being centered on an object? This can be easily reproduced by adding a dynamic layer as base map (noticed in a local dynamic map service layer rendering an map package, have not tried a tiled layer), have its brightness set to 100, adding a graphic to a graphics layer, having it routinely update its location on the map, and having the map center on its location as it updates.
The good news is that the map consistently appears to restore the base map content after panning unto the graphic, but it sometimes tend to turn black at times when it restores it at a slower rate. Another is that this does not occur at all when the opacity of the base map layer is used, instead, to resemble a brighter display by reducing its value.
