Naming nitpick: onChanged isn't really a great name for a signal. Usually, "on" is used with slots.

What about connecting `Compositing::animationSpeedChanged` to `Compositing::updateSettings`? e.g.

  connect(this, &Compositing::animationSpeedChanged,       this, &Compositing::updateSettings);

Given that m_changed is not set to true when anything has been changed, there is a chance that we won't send a reinit request.

We probably need to save the return value of `m_settings->isSaveNeeded()` before calling `m_settings->save()` and check it here.
