glitch

After many tries, I was finally able to pass beyond the clover loading text [ verbose ] where it got stuck on blacks screen before, but I got this weird graphic glitch on my 5700 XT [ DisplayPort]. I tried the other ports as well and tried disabling the iGpu [ UHD 630 ] in Bios [ Internal Graphics = disabled ] but still same glitch. I can still see the installer and interact with it but can't read clearly since its all over the place.

Vanilla Install

I’m using iMacPro 1.1 / adding agdpmod=pikera was able to boot but with graphic glitch. Without it I get black screen.
