Is visual clipping common for either too much or too little b12?

I've recently resolved a lot of unilateral ear issues (fullness, low frequency hearing loss, balance issues and vertigo episodes) by taking a sublingual methylcobalamin supplement. I was actually misdiagnosed with Meniere's disease until I looked at my genetic data and discovered a b12 recycling problem and saw immediate relief when I started taking it.
Now that it's been a few months of those symptoms completely resolved, I'm noticing a bit of what I believe to be defined as 'visual clipping' whereby it feels like you miss a frame or there's a bit of a jump in your visual surroundings when you move. It only occurs once in a while but it actually seems to be more noticeable on the days that I take the b12 supplement. I was also taking a multivitamin that includes what a b-complex would but I've been experimenting with not taking that to try and get to the bottom of what can be causing this now.

Would it be nerve sensitivity by having too much b12?
Can it be a symptom that I still don't have enough b12?
Is it just the slow process of my system getting back to normal with the b12 deficiency rectified?

Looking to see if other have any similar experiences to this particular symptom. Thanks!
