glass on supercharged slime machine renders wrongly when moved after a long while

when you look through moving glass when it moves (at least when going through new chunks on flying machine) the glass renders stuff real glichy. you can see all sides of the front row of glass and the water was sethrough. the slime machine i used with this was https://www.youtube.com/watch?v=pRi926Au7EY and i added glass at the front. i was waching youtube while dis was happening. you have to use the machine for quite a while before it started happening.
