If the value is still NO, IIRC there has been a long-standing bug with NSProgressIndicator in certain views. Try calling [[self.loadingProgress superview] setNeedsDisplay:YES] after you stop animation. If that works, that will be confirmation that the bug still stands...

Yes, both of these are trying to force an update. As I said before, the bug isn’t that the area isn’t marked dirty, it’s that the visual-updating code refuses to acknowledge it. The updating code only triggers when something outside the view, like the toolbar, indirectly forces a redraw.
(It does happen sometimes, just the very first time I run the program. So the issue is timing-related.)
I got a solution now. After I stop the animation, I switch the progress indicator from bar to circular. That change is recognized by the updating code and triggers the auto-hide. (I guess the bug is only in the bar code.) I have to put a change-back to bar-style in my progress-starting notification. The animation is sometimes cut short, especially during the normal cache-preserving reloads, but it’s livable.
