Screen flicker / glitch and freeze

I’ve got an issue with a 12 retina macbook. Im getting a screen flicker / glitch that is very random. Sometimes it’ll happen upon first boot, sometimes it’ll happen when i login, and sometimes i’ll be able to get into mac os and then it’ll just happen randomly. I’ve tried to get to a stage where i can reinstall macos however if i can get to install it, half way through the installer it’ll glitch out.

The macbook will also occasionally just freeze on logging in without the flickering issue.
