It just seems stupid having a view color because the menu draws its own
background, so we are just letting the app_server draw a background which
immediately gets drawn over. And that was what was causing the flickering
in menu bars and to some extent menus (though in my testing it was much
worse in the menu bar.)
Mayble problem actually happens because background color and bitmap are
drawn by app_server and BView contents are drawn by application. It
happens asynchronously. When app_server validates view it draw background
and send validation request to an application. As result background is
drawn even if application is hang.
