Description

The code below on started doesn't stop(), complete() or running = false.
alwaysRunToEnd must be false or the loops do not be Infinite (but it will loop the specified number), which doesns't make for a smooth transition.

This might be fixed but I did not find a bug report and could not test on a newer Qt version.

       SequentialAnimation {
                id: seqAnim
                loops: Animation.Infinite
                alwaysRunToEnd: true
                OpacityAnimator {
                    target: whiteRect;
                    from: 1;
                    to: 0.6;
                    duration: 200
                }
                OpacityAnimator {
                    target: whiteRect;
                    from: 0.6;
                    to: 1;
                    duration: 200
                }
                // disable alwaysRunToEnd and this for workaround
                onStopped: whiteRect.opacity = 1
            }
