There are no issues with Albinos and the "poor vision" thing is an old wives tale that needs to die.

Slight neuro issue has been documented in SuperBlack/SuperCinny. May or may not be the case here, I would suggest keeping an eye on her and seeing if the behaviour is temporary or sustained. Even if it is sustained it may not be a neuro tic, I have a couple animals that intentionally bluff strike a few times before actually making their "kill" strike. So long as the animal is eating and otherwise healthy I would not stress it
