Problems with gpu

[RehabMan]

Reinstalled macOS, patched kext and now it stuck at garbled apple logo.

Mobo: manufacturer/model + bootloader(Clover/Chameleon/Chimera)
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
Mobo: HP ProBook 4540s (Clover)
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768

Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx), and graphics capabilities. For a laptop, these details are important and affect critical installation procedures.

Note: When specifying your bootloader, if using Clover legacy, please be sure to specify "Clover legacy"). Specifying "Clover" will be assumed as "Clover UEFI"

Done. Attaching cpu-z report just in case.

Done. Attaching cpu-z report just in case.

Boot verbose, show photo. Attach EFI/Clover folder as ZIP (omit 'themes' folder).

It booted with graphics acceleration somehow But I've noticed weird black flickering:

Is it fixable? Attaching ioreg and terminal output:

You could try different ig-platform-id values as well as FakePCIID+FakePCIID_Intel_HD_Graphics, but the problem is likely due to incorrect DVMT-prealloc setting.
