Comment (by leavengood):
Well maybe making the menu background transparent was not a good idea. 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.)
Though with all this I have to wonder why there is flickering at all
because I thought Stephan made all app_server drawing double buffered.
Maybe the issue here is the app_server draws the default view color
background, and then the client side drawing happens, and those two sets
of drawing operations are not double buffered together, but each is
separately double buffered.
