Having a glitch when running a script that makes a rig appear

So the video shown below shows a flickery type of glitch. It has CanCollide to false and Transparency on each part set to 1. I have a script that makes it collidable and sets the Transparency to 0. Only then does the flicking glitch occurs is after the script is ran.

when any 2 parts render in the same spot, this glitch happens. it is known as z-fighting

edit: i should include that it is very known, and unlikely to be fixed by roblox themselves.

Alright cool so you think I should just pull it from ReplicatedStorage if theres no other solution?
