Broken Olarila EFI for Broadwell... glitch graphics found/with workaround

[theokeist]

I reinstalled mac multiple times, Catalina, Monterey and suddenly it started to be broken,

It started to work again after reopen laptop lid - but this is ugly workaround

I tried updated EFI from forum as well as my EFI folder from here, which worked previouse times..

Below is video with issue.. during boot, install, and same thing after install when login & power on pc
