I'm hoping that 10.11 will perhaps be the release that refines things quite a bit, concentrating on stability and generally cleaning up messes like this.
Let's remember that they did a fairly major overhaul of everything with Yosemite. This is just how software works sometimes. But you're right, there was a certain amount of UI stability during the Tiger through Snow Leopard era that I wish that Apple would get back to.
Try switching between the tabs in the "About this Mac" dialog. The framerate is truly shameful. Astonishing that it got approved at all. I had to try it on a couple different Macs at the Apple Store to believe that it wasn't some random problem I was seeing.
