You can still end up with the jarring flash. Say you delay 100ms--if the action takes 120ms, you have the same problem.

- TeMPOraL 7y agoFlash is good. If the state transition is "no indicator -> spinner -> checkmark", then if the user notices the spinner flashing for one frame, that only ensures them the task was actually performed. It's a real case, actually. I don't remember a name, but I've encountered this situation in the past, and that brief flash of a "in progress" marker was what I used to determine whether me clicking a "retry" button actually did something, or whether the input was just ignored. It's one of those unexpected benefits of predictability of UI coding; the less special cases there are, the better.
