In my case, when I set Title property for the pages, I'd say it is not flickering of entire window.
It looks like caption twitching.
When you switch items, caption bar disappears and appears again with new title on it.
Anyway, it looks a bit ugly.
Please fix ASAP!

Currently, I get a different effect.
Following a sample app shown here https://github.com/xamarin/xamarin-forms-samples/tree/master/Navigation/MasterDetailPage , the Mac variant crashes when clicking on the (navigation) menu, throwing a NullPointerException from Main.cs.
Is there a relevant unimplemented API on macOS that we need to know about?
