My impression is that some parts of Windows force animations to play out fully (probably not allowed to skip keyframes?) instead of real-time. So when something is animated, and the connection is bad, it takes ages for the animation to finish. Also, animations stay enabled in the first place in some places when using RDP is a bug in itself.
