Need more details on your hardware (monitor, how it is connected), and supporting "Problem Reporting" files.

You did not patch the framebuffer for HDMI. Your display shows connector-type as DP <00 04 00 00> instead of HDMI <00 08 00 00>.
And to eliminate hardware/cabling issues, you should test on Windows too.
Also, check BIOS settings (DVMT-prealloc).

But my display is connected with DP.

Ok, my bad. For some reason, I read it as HDMI.

I tried another values of DVMT, no results.
Cable is good on windows.

Try other ig-platform-id values.
 
Changing to 18.1 model didn't help me. I used UniBeast 8.2.0 for creation boot flash. Then I installed clover 4411 and put any others kexts (FakeSMC, Liu, IntelGraphicsFixup, RealtekRTL8111, AppleALC) into EFI/Clover/kexts/other folder. Kexts are taken from "Downloads" section. My BIOS settings follow recommendations from this site.
PS1 Sierra works perfectly
PS2 Without IntelGraphicsFixup is much less flicker. Any ideas?

I can confirm that with iMac18,2 there is flickering. Chaning to iMac18,1 solved them on my rig.

Intel HD630 , i57400

This is only after 10.13.4 update, on 10.13.3 iMac18,2 works as it should.
