I am trying to install macOS on my Toshiba Satellite P75-A7200 laptop. I managed to configure OpenCore as much as I knew, utilizing Linux to get DSDT and get ACPI configured.

I made the configuration using https://dortania.github.io/vanilla-laptop-guide/. I configured GPU using WhateverGreen's Framebuffer Patching Guide. I even tried the AzulPatcher4600_equivalent.plist. I always get into this glitchy screen. (OC.zip and config.plist)

See images to see what I am talking about. Help would be appreciated. (I attached the latest open core log)

I managed to get the screen less glitchy (but with weird colors and weird resolution) by taking an open core config.plist from a laptop with a similar configuration from GitHub (attached bellow as randomconfig.plist)

try enabling csm in your bios
 
That did not work. After enabling csm in the bios, I couldn't boot.
I have exact same gpu, I also experienced this issue and csm fixed my issue @Feartech is right this is the solution.

Try press F11 in Clover and boot macOS.,
Edit:Sorry you're working on open core try to reset nvram maybe this will fix your issue.
 
I leave you my EFI OC you can get the video configuration from here

I leave you my EFI OC you can get the video configuration from here
Hi there,
i was having problems with the boot resolution being very low until logon and i couldnt find a way to fix that without having glitches when i was disabling the csm at the logon.
I saw your post and i have checked to see what was wrong on my system and i found out that disabling the csm and adding your AAPL00,override-no-edid fixed my problem but it seems that the colors are not so accurated.
I was wondering if you can help me getting my EDID or tell me how did you got yours, all the steps.

Thank you.

I succeded to extract the EDID with Monitor Asset Manager for Windows, i copied the HEX on AAPL00,override-no-edid but i was still having the issue and i fixed everything by just replacing this HEX 80A07038 with yours 804A7138 assuming that is for refresh rate.
 
Hello again,

i just saw that for working is using a 55Hz refresh rate and i was wondering if you know how to change it to 59Hz or 59,99Hz to be more close to 60Hz.

Thanks.
 
Screen OK, but USB 3 not working

I have the same laptop -- Toshiba P75-A7200. I have Catalina 10.15.7 running with full acceleration etc. It also glitches for me as soon as I get to the log in screen. BUT, I close my lid/screen and wait for the screen to go blank, then when I open up the lid the screen wakes to the perfect state. So for me the glitch is temporary. I just do this 'close lid' trick for 30 secs every boot or so and get on with my stuff.

HOWEVER, I cannot get my external USB drive to show up. USB 3.0 does not work. Bluetooth and webcam work, USB 2.0 works. If anyone has a solution for USB , do let me know.

Thanks!
