Color banding with Dell G7

[vinhtq115]

Does anyone know how to fix the color banding issue on Intel UHD Graphics 630? I installed Mojave on Dell G7 with Intel UHD 630. Everytime I use something that blur my wallpaper like Launchpad or Dashboard, this happens. (Forgive me, idk how to describe it in English).
This is what it looks like when seeing directly

but it's perfectly fine when I take screenshots and see it from my iPhone

Try plist from the guide:
https://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/

(note: it is probably an EDID issue, so also look into FixEDID).

Try Skylake Spoof.

With the plist UHD 630 in the guide, it still looks like in earlier screenshot.

Sklylake spoof not applicable to UHD630.

You failed to attach any PR files representing this scenario.
But if you're sure you did it correctly, then it leaves EDID fiddling...

Here are PR files. FixEDID shows the same for both my and your config.plist.

Your ioreg shows obvious SMBIOS truncation.
You need config.plist/KernelAndKextPatches/DellSMBIOSPatch=true

You could try other (valid) ig-platform-id values, or try patching EDID.
Also, you have not yet implemented backlight control.

Keep in mind unresolved issue with UHD630:

These are PR files when using your config.plist + DellSMBIOS patch.

About not implementing backlight control, I guess it is not the cause because I already implemented it in my config. I will look into another solution.

And about the 3 minutes, it's not a big deal to me because I will restart it by holding Power since it's faster anyway.

Your ioreg proves your assertion false.
