I see all the pixels kind of popping on themselves (not popping like rendering new stuff) but like popping for no point, am i crazy? is this normal? U can particularly notice it when I look down at the trees

I've saved and did it again for 2 times yet it still doesnt work- I'm at the door of this and I found all the symbols and i also checked on internet and they are correct, yet, when i go with the cilinder to open the door it says somethings wrong, can anyone help me? thx
