There was an off-by-one error in DelayedControls::get() when picking controls from the queue to return back to the pipeline handler. This is only noticeable as small oscillations in brightness when closely viewing frame while AGC is running. The old StaggeredCtrl did not show this error as the startup queuing mechanism has changed in DelayedControls. Fix this by indexing to the correct position in the queue.
