Screen Flickering. Is this normal?

Hello fellow HP enthusiasts,

I've recently acquired an HP Prime G2 from an UK seller, but the screen seems to have a lot of jitter whenever it's scrolled, mainly in the Home and CAS screens.

Here it is: https://youtu.be/v9V_jHZpJrc

It's not very noticable on video but it makes me crazy. Updating the firmware didn't help either. Does anyone else have this problem or is my unit possibly defective?
