Blender objects with "Array" modifier are blurry and slightly delayed when animating

i have this really cool model and i want to animate it
when i animate it, all the objects with the “Array” modifier go blurry and are slightly delayed when animating

it’s barely visible but i can see it:

is there a way to fix it? or is it not even visible in roblox?

nevermind, it’s only visible in material preview mode
