That's not a layout change; it's a frame model change...
but in other cases no reflows are going to happen. To avoid flickering, I need to know whether any reflows are pending, and wait to show the view until afterwards, but if none are pending, show the view immediately. What is the best way to determine whether there are any pending changes?
On the reflow branch you could check the DIRTY and DIRTY_CHILDREN framestate flags. That won't help with pending style changes, but it'll work to detect cases when the popup or something in it needs to be reflown.
