  I've just commited change to NSWindow.m which have to improve 
  overall window drawing. The idea is to draw window's content view
  before backend window starts drawing on screen. After this change I
  noticed that almost all windows(including menu, appicon) draws without
  turning white (or black for back-art) first. Although, some panels
  (Save Panel, Open Panel), have NSBrowser and button while other content
  draws with delay and old behaviour. Maybe panels should be checked?
