<< Solved >> Internal screen wrong color/banding on KabyLake - Intel HD 620 [Mojave/Catalina]

[prospoerous]

Hello, you guys! I'm got some problem with my Hackintosh laptop, detail below.
My laptop's information:

• Model: Acer E5-575
• CPU: Intel Core i3-7100U
• IGPU: Intel HD Graphics 620
• RAM: 4GBx1 + 8GBx1 => 12GB RAM Bus 2133
• Wifi: Replaced with DW1820A.
• Clover: Clover 5106
• OS: 10.15.3
• UEFI/LEGACY: UEFI
• Storage: SSD M.2 WD Green 120GB + 500GB HDD

What's working? => Touchpad, hdmi, audio, USB port, brightness, hotkeys,...

I patched framebuffer with Intel HD 620, you can see in the "EFI/Clover/config.plist" I attached.
And with mojave&catalina all 3rd party application is so slow when open than default and system app. I take about 20s for open, (High Sierra 10.13.6 is open so fast, ~2,3 seconds) (If you know this problem, please help me, else you can skip this line)

I can adjust brightness or plug the HDMI cable in/out without problem. But the Internal screen is wrong colour or depth colours or banding like this (I don't know how to call it):

____________

With 10.14 & 10.15 when I closed lid or sleep, then wake the laptop up, the internal screen is normal, no more effect by colours

Thanks for reading, hope you can help me!
