      If the OpacityAnimator animates the opacity of a new item from 0 to 1 in a StackView, the item can be shown for one frame with 100% opacity and then its opacity will change from 0% to 100%.

      With the NumberAnimation, this issue is not reproducible.

      I've attached two basic applications to this bug report, which demonstrate the issue. Glitch-OpacityAnimator.qml uses an OpacityAnimator for the enter transition, Glitch-NumberAnimation.qml uses a NumberAnimation for the enter animation.
