The flickering menubar icons drive me insane. It's proof that Apple has is either unwilling or unable to commit enough resources to OSX to ensure that its quality is consistent with what users have come to expect.
Quality is important but it's also important to move the platform forward. This flickering menubar issue sounds like an issue maybe related to the changes with multi-monitor support and/or the changes made to improve UI performance on HiDPI displays. Just speculation so who knows but if so they might be a necessary evil. As far as the level of quality we expect this is where I start to wonder if I'm living in a parallel universe or something. My experience over the years is misbehaving menubar apps could make the entire menubar stop working sometimes even requiring a restart and icon cache issues in the dock/menubar were not uncommon. I haven't had any of those problems on 10.10 yet so maybe I'm more inclined to believe these changes (and bugs they may cause) are for the best interest of the platform over the long term. Who knows though -- if I was experiencing the blinking menubar problem I might miss the days of only dealing with an occasional menubar crash.
