Screen artefacts at startup for few seconds

3 posts in this topic

Recommended Posts

Hello,

I recently setup my hackintosh running of a 7370Pc-Pro mobo and an i5 8600K. -

I don't use a dedicated CG but my HD 630 IGPU that wome with my cpu.
My bootloater is opencore.
But i'm facing an issue :
At bootup my screen is full of artefacts (screehsot bellow) but after few seconds it come back to normal.
It seem a driver do not initialize correctly. I made some research on google and i found that this issue is called "screen gabbing" but i couldn't find any fix for my problem.

I already updated lilu and whetever green. I checked too my igpu plateforme id and my device properties.
Does someone know how to overcome this problem ?
Thank you !

 

 

Ps : in the screenshots bellow you will be able to see the before, after.

Most likely an issue of high resolution or screen EDID. You could try to configure Clover to inject the latter to begin with. Use Clover Configurator app to that effect.

I'm using opencore,

how i could implement your fix using opencore ?

      Hackintosh post

      Hi Everyone.  I really need some help.  My GPU just went out so, I'm replacing my Vega 64 with a 5700 XT and was planning on using my iGPU until the when/if the 5700XT is supported  in a mackintosh.   

      I've currently got a GB Z390 M Gaming with an 8700K.  16GB Ram. Running Mojave 10.14.2.  Right now everything is working perfectly (except I have to pull my Vega 64 to get the water block looked at - the pump was making weird noises this morning, but is still working at the moment as I use this sparingly).   
      The hack boots.   [Intel GPU shows up in system report](https://imgur.com/a/rwhDbSM) but the problem I'm facing is there is no output to it.  
      Does anyone know what I've got going wrong here?  I appreciate any help and will make a donation to a charity to celebrate when I get this figured out.  I've been working on this on and off all dang day.

      Hello folks 
       
      I am having issue with my vanilla Mojave 10.14.6 (18G87) freshly installed with freshly made config.
      The issues are: some of the animations are stuttering like opening Launchpad, making selection on desktop the rectangle stutters, moving windows etc. is delayed a bit or stuttering, pictures on web like Unsplash are loading very slowly (my internet speed is okay). Very rarely I have my iGPU working smoothly and that happens just for like 10-15 seconds.
       
      My configuration:
      Drivers I have installed on my Clover (5037 or newer):
      Kexts I have installed (I updated them recently to latest):
      My config: https://pastebin.com/AWvuJsYq
       
      Yes, I have been faking my iGPU with device-id and ig-platform-id as Kaby Lake (it was just easier for me tu run when using High Sierra with my GTX 1060 + quick sync (iGPU) because it was showing there as Kaby Lake) but that faking shouldn't have any impact on that iGPU performance, right? I know a person who is using UHD 630 on 4k 60Hz monitor and it works just fine for him so that's something with my setup.
      Do you have any ideas what should I check or change?

      Hello everyone 
      I decided to open this thread for Intel HD Graphics 530 SKYLAKE 
      This GPU seems to be problematic with Hackintosh , specially if you intended to use it with 4K monitor or Multi-Monitor .
      Simply after you followed all the right instructions to patch framebuffer using Lilu.kext and WEG as described here in @headkaze 
       
      "Gen 6: Skylake (Intel HD Graphics 510-580)
      - S/L/E/AppleIntelSKLGraphicsFramebuffer.kext
      - Support started with OS X 10.11.4
      - device-id: 0x1916 0x191E 0x1926 0x1927 0x1912 0x1932 0x1902 0x1917 0x193B 0x191B
      - AAPL,ig-platform-id (desktop): 0x19120000 (default)
      - AAPL,ig-platform-id (laptop): 0x19160000 (default) " 
       
      Simply after Apple logo boot go to black screen 
      I can't use platform-id : 0x19120000 as suggested is a default 
      I am sure Bios settings is correct , Clover is correct , Kexts , ...etc 
      But end always with Black screen 
      I've seen a lot of people have the same issue when googling it , but no solutions at all 
      I want to know what is the reason that cause the black screen ?!! 
      Is 0x19120000 not default ?
      @vit9696 WEG issue ?
      Something else? @PMheart @vandroiy2012 
       
      FYI : using  Displayport 1.2 , using HDMI = Black screen 
       
      Only solution is using Platform-ID : 0x193b0005 
      Now you can boot normally but Monitor in this case seen as TV NTSC 
      Is 0x193b0005 is the default Platform ID ?  
      Can someone help us please ?
      Thanks
