I've been noticing this for a little while now. For some wacky
reason, the thread that tickles default buttons and progress
indicators to update is somehow no long working in my app. Default
buttons don't pulsate and the progress indicators don't spin. The
GUI is fully responsive otherwise, but these items don't animate
properly. Does anyone have any clue as to why that would happen?
I've completely stripped this project down to the absolute bare bones
and it shows this bug. Simply launch the app. You'll see that the
default button in the window is NOT plusating like it should be, and
if you click it, you'll see that the progress indicator does NOT spin
like it should.
One of the views in the hierarchy is set to have a CA layer (through
setWantsLayer). If you turn that off, it works. If you move the button
and progress indicator to different (certain) views, it works. (Other
combinations don't work.)
Here's a project:

Looks like a Core Animation bug to me.
