Dell E5430 HD 4000 glitches/artefacts even using WEG and framebuffer patching

[bebetoalves]

Hello, I have a Dell Latitude E5430 non-vPro (8GB RAM/SSD WDGREEN 240GB/i3-3110M) with Catalina installed on it, I'm using OpenCore for this. Almost everything is working, but I'm having problems with the HD 4000 (1366x768) video card. I followed the entire tutorial in the WEG documentation for my video card model and I even did the framebuffer patching, I also did the SSDT and DSDT patching, but this video card continues to present some problems, the biggest of them are glitches and artifacts on the screen when the system is on.

 

I recorded some videos showing this:

Boot glitch: https://streamable.com/pksh89 (It used to be worse, somehow the glitches reduced.)

Shutdown/reboot glitch: https://streamable.com/nsl3vd

System on: https://streamable.com/bsjkt9 (glitches on the bar)
