An animation can display an incorrect frame upon having its visibility re-enabled, resulting in a noticeable flicker. This can be prevented by setting the mesh's 'Visibility Based Anim Tick Option' to 'Always Tick Pose and Refresh Bones'.
Place a skeletal mesh set to play an animation.
Duplicate the mesh leaving it in the exact same position.
PIE and toggle one of the skeletal meshes' visibility and hidden in game as the animation plays.
Expected: Whenever visible, the animation of the toggled visibility mesh should match the un-modified mesh.
Result: There is a noticeable flicker where the toggled mesh is in an incorrect position for the first frame after being made visible again.
