Problem with Intel HD 630 in Catalina 10.15.7

I’m using MSI GV72 7RD with : CPU : i7 - 7700HQ GPU : Intel HD 630 + nVidia GTX1050 (disabled via wegnoegpu) Using OpenCore, WhatEverGreen and Lilu (all latest version)

I have a problem with Graphics, which is blinking in black/dark and Transparent area. QE/CI works fine. Just blinking like low Refresh Frequency and you can see my video (here)

Things i have tried : - PlatformInfo : MacBookPro 14,3 + 14,2 + 14,1 with 0x591B0000 - 0x5912 not working too with all PlatformInfo

I don’t know what to do now and how to solve this. Thank you verry much for your help.
