Description
What is the problem or limitation you are having?
Previous discussion:
Except for WinForms, none of the native platforms make any UI changes visible until the next main loop iteration, so we're doing a lot of redundant work. And even on WinForms, excessive updates will make the UI look unstable, and probably reduce performance.
This is particularly an issue with layout – if you insert N items into the layout, or you have N labels and you change the font or text on all of them, then we'll perform N layout passes, which will cost O(N ** 2) time.
Describe the solution you'd like
Delay layout updates until the end of the current main loop iteration.
This may also affect non-layout style properties if they're assigned multiple times within a single main loop iteration, where only the final value really matters. But that's likely to be less of a performance issue, so it might not be worth the effort.
