Weird Artifacts in Mac Installer

Config : I5 4690 + HD 4600 Biostar H81 HMV3 RAM Gskill 4*2 1666 MHz 240 Gb ssd.

Opencore 0.67 Macos Catalina

The artifact is like those old school crt without signal.

It didn't happen yesterday, I couldn't install yesterday due to no Internet and Today I am stuck.

It recovers for a second after sleep and does that pattern again.

I had success with this machine in past with GT710, but I wanted to try HD4600 itself.
