Signal loss on boot after update latest IntelGraphicFixup?

[telepati]

Hi, guys, after update v.1.2.4 to v1.2.6 I am getting the signal loss on boot. Normally I am just getting boot glitch with v1.2.4 and I can live with that but after update to v1.2.6 first boot glitch come then signal loss coming then boot. Normally I am not using any ig-platform-id and injection on config files and my HD530 working as an SKL CRB after update v1.2.6 it shows as an In HD 530 on about my mac. I made videos for clarification for my problem. How to get rid of this signal loss problem? is it possible to use v.1.2.6 as an SKL CRB?

v1.2.4 just getting boot glitch

v1.2.6 boot glitch and signal loss and its automatically change SKL CRB to Intel HD 530

I used to igfxfw=1 boot arg with v1.2.6 and it doesn't help.

Attached gen_debug files.
