The past few times on Xbox ever since the latest update to the A350 I have noticed that I only can see the engines turning when a high power setting is set. If engines are on at idle or even 40% thrust the engines do not spin at all but instead look like they are powered off. But you can hear them. Please fix this on Xbox.
I have attached a screenshot of the plan holding short Runway 09L at KATL where the engine is powered at idle, but you cannot see the engine turning.
