> In the meantime, I compared all the code of my previous version against the code of the new version, looking for changes that might cause this difference in behavior. The only really big change is that my new version makes use of the new NSVisualEffectView when running under Yosemite. I wonder if Apple accidentally or on purpose did something in implementing NSVisualEffectView that would cause this delegate method to be triggered. It doesn't seem likely, but I can imagine that NSVisualEffectView might be doing things behind the scenes that are very deep in the system.
Just my two cents : if NSVisualEffectView is one of the APIs that
triggers a GPU change, then you're likely to get a "monitor changed
notification" when the application starts, since GPU changes will be
handled on the OS side as if the display was detached from the
integrated GPU and attached to the discrete GPU.
