Materials / geometry rendering in view.

Greetings,
I will be up front, I am by far more of an artist than a programmer so I’m not sure if there is a fix for this, that being said.
I have been working on a minecraft (UE Edition) for a bit more for practice than anything else. However if I go back and forth from a block I can see rendering of mats / geometry.
I’m not sure if this is just something that will happen with this Engine or if I am going about something badly, or perhaps even a setting can be ticked.
I have posted a video showing what I mean.

It might even just be my rig not catching up fast enough, just thought I would ask in case anyone knew.
