Advanced OpenGL apps may cause graphical glitches and/or GPU hangs

[VisualEhrmanntraut]

After evaluation, I do not recommend using this hack kext because it just lowers the OpenGL version, which works around some dysfunctional OGL extensions. Do not ask for help or report its use here. On some systems or apps it even causes the hardware acceleration (of apps) to be completely disabled. The goal of this issue is to track progress finding and resolving the underlying issue, not working around it.

BFixup-master.zip

BFixup.kext.zip

The kext did fix this problem.

Just use that BFixup.kext and the Lilu.kext provided in BFixup-master.zip.

Then, you will find Chome/Edge or any other Chromium-based browsers works fine.
As well as vscode, etc.

Guess nootedred just can take this kext in its source code.

I've got some suggestions on Hackintosh/Ryzentosh, especially for problems with trackpad or things like that.
In case someone is gonna need that, I'd leave the link.

Edited by me, Visual, to attach the following information that may be useful to future readers

This kext patches the dyld to force GLEngine to report a lower OpenGL version. This is not a proper fix and merely works around some specific broken OGL extensions. I do not recommend using it.

[VisualEhrmanntraut]

Also I found that in AMDRadeonX5000GLDriver, function _gfx9_HwInfoInitData and _amdUbm_HWL_Init, that the device family is hardcoded instead of being read from the accelerator.

[txrm]

DOSBOX's OpenGL freezes the system immediately, looking into what triggers it since it's a fast and reliable crash.

Config field is output = surface | overlay | opengl | openglnb | ddraw

Not working for me here. The system fails to boot after I enabled BFixup.kext; it instantly reboots upon reaching the Apple logo. When I turn on verbose mode, the last line in the log states something like, 'AppleNVME Assert Failed (0 != Data),' followed by an immediate reboot. Whether using the provided Lilu.kext seems irrelevant. (5900HX, Ventura 13.5.1)

it works for me.
BFixup.kext needs to be placed before noodred.kext

@b00t0x can you provide a web page where your code change helped avoid firefox crash ?

@jalavoui Firefox causes system freeze not on the specific page but even on the settings window. (5850U + 12.6.8)

Are there any settings in opencore that can temporarily disable GPU acceleration?

[VisualEhrmanntraut]

@shenfu1991 You just disable the kext

[jalavoui]

@b00t0x sorry to ear your firefox so crasy
anyway your code sugestion didint work for me and might break vcn decoding
the only "fix" that worked for me to avoid firefox scroll bug is comment this line in 5000
// {"__ZN29AMDRadeonX6000_AMDAccelShared11SurfaceCopyEPjyP12IOAccelEvent", wrapAccelSharedSurfaceCopy,
// this->orgAccelSharedSurfaceCopy, !catalina},
is just a workaround till something better comes up
i have this terrible link to check firefox crash
https://arstechnica.com/
you can get crash log if you use tor browser
so for me firefox only crashes on certain sites that use unsupported opengl calls
i'm happy with that for now

this is tor brwoser crash log

but all you will get is a broken firefox interface

there's also a possible issue with high ress lcds (>4k) that can be causing issues. i hope someone report this

[VisualEhrmanntraut]

Talking about that workaround... I just realised something:
With the VTable wrap hack the team ex-member came up with, if the called function inside the wrap calls another virtual function in the this pointer, then the wrong function gets called

[jalavoui]

hmmm maybe that bugs iosurface

Ways to make Firefox work:

1. On termial:
   cd ~/Library/Application\ Support/Firefox/Profiles/*.default-release/
2. nano prefs.js
   add this line: user_pref("layers.acceleration.disabled", true);
3. Launch firefox:

• open: about:config
• search: webgl.disabled
• change to: true

4. restart Firefox

Chrome seems to die due to a command sent by libGLES2. Relevant log attached. (This is an Electron app, therefore uses Chromium)

[SiddharthMant]

It seems that this issue doesn't occur if I don't increase vram to 2 gb. I was using Hackintosh with 512mb vram (default for my laptop) since the last 2 weeks and although the UI would slow down, there were never any artifacts in chromium based browsers (edge) and system never crashed either.

There were a lot of errors in kernel log about amd driver failing to allocate more vram (512mb). But the system worked fine.

with 512m vram if you open chrome://gpu acceleration is disabled so you need to increase vram for it to work. i use 2g

thanks a lot for the kext, would you mind sharing the sources for it?
and, with this enabled do you know more or less what apps are still having issues? can't try it myself yet but thank you for sharing.

Your patch matches against GLEngine, correct? @jalavoui It appears my command has some kind of issue

[VisualEhrmanntraut]

Yes, dunno why it doesn't work. Sorry about that. I've opened up GLEngine and see what you are patching. Is this changing the supported GL version, or is this for the supported GL extensions?

Whether using the provided Lilu.kext seems irrelevant. (5900HX, Ventura 13.5.1)

Edit: Seems kext conflict happened here. Fixed by modifying the load order in config.plist. Moving BFixup.kext to make it higher than NVMEFix.kext (Not sure if this is the conflicting one) seems doing the trick.

[VisualEhrmanntraut]

So it does actually lower the GL version

[laris]

i doubt Alacritty will work anyway maybe can you try build Kitty and hack gl.c to something like int gl_minor = GLAD_VERSION_MINOR(gl_version)+1;

yes VisualEhrmanntraut i posted the picture above no crashing chrome shows this

i mod the patch to 3.3 to make alacrity happy but it just crashes because (i think) os x just refuses to enable the needed extensions that's why i check and let it stay at 3.2 as most apps are happy with it

Thanks for your tips, I use WezTerm as alternative in short time.
Will try build Kitty in future.
