The problem: I'm removing a ui component and adding a new one. I don't want there to be any frames rendered between the two calls. In other words, on frame x the first ui component should be visible. On frame x+1 that ui component should be hidden and the new component should be visible. The behavior im seeing is more like frame x+2 or x+3, so there is a visual "pop" The goal: I want to remove a component from a display list and add a new one without any popping. Ideally it'd be something like... function swapUIComponents(newComp:UIComponent, oldComp:UIComponent, displayList:DisplayObjectContainer) : void { mx.core.Application.application.updateDisplayBuffer(false); var oldIndex:int = displayList.getChildIndex(oldComp); displayList.removeChild(oldComp); displayList.addChildAt(newComp, oldIndex); mx.core.Application.application.updateDisplayBuffer(true); } Anyone have any thoughts on this?
