Yes but that doesn't help fixing the problem...lol Can someone please give a straight answer on how to fix it, i'm in the same boat here. My hackintosh boots up fine, it's not a big of a deal for me however i like to see things work perfectly.

I know but there is nothing you can do. The new AMD 10.14.5 drivers do this for everyone and so far, no solutions.

I wonder if this issue affects real Macs too.
As those cards only fits in MacPro's, being PC GPU's, bootscreen is not visible on real Macs. Less chances that it'll be fixed. Mac cards needs special vBIOS to display boot process...

As long it is just a cosmetic issue, OK. But if that also have effects on the overall macOS , less good

I have the same issue updating from 10.13.6 to 10.15.1 it works for about 10 seconds then it gets the purple lines, doesn't update progress and eventually goes to a black screen. No way to tell how long iz left on the update.
