My thought on this bug was to fix it in the scenegraph, rather than forcing a complete repaint in the toolkit. The scenegraph tracks the state of what is dirty and would only need to repaint if something has changed (and probably only those parts that have changed).

@arapte Can you take a look at this and see what you think? I am not able to look at it for at least a week.
