Graphic Artifacts Problem - Solution

[Kaijun]

If you guys met some kind of graphic artifacts problems at the menu bar,

then try something below:

Two Solutions:

• download AppleIntelFramebufferAzul.kext.zip and replace the old one (back up it if possible). Notice it's only tested for 10.9.x
• Change the Color Profile: Preference - Display - Color (try sRGB IEC profile)

however i don't have such kind of problem, so that i can't do some further research because i don't know if it works even if i make some progress... but i think it may be the problem with Framebuffer. you guys can try to modify a suitable Framebuffer and see if it works!

I confirm second solution. I'm using sRGB IEC profile since I had troubles with graphics and everything works fine.

It looks like graphics artefacts are caused by setting wrong ig-platform-id for graphic card in DSDT. @Kaijun can you try other ig-platform-id, maybe it will fix Preview.app.

[Kaijun]

@Virusak yeah it could be. but you know, there's no problem with my laptop. so even if i change the ig-platform-id and start with the new dsdt, i still can't tell if the ig-platform-id works properly for you guys. so the best approach is that you guys change the ig-platform-id manually by yourself (by using MaciASL.app) and test which ig-platform-id is the best for you! (there're probably more than 10 ids)

Where to put "ig-platform-id" and any idea what values we have test? I have graphics artefacts and it's quite annoying.

Thanks for all your support and great work!

P.S. For my laptop this works:

"AAPL,ig-platform-id",
Buffer (0x04)
{
0x00, 0x00, 0x16, 0x0A
},

@TheGuild already solved? did it work for solving the graphic artifacts problem?

[vasil-boshnyakov]

Yes, this change to ig-platform-id solved my issue with the graphics artefacts.
Now everything works just fine :)

[Majkwin]

@TheGuild , can You write a brief guide how to change it? Or maybe upload your dsdt.aml file if you haven't change anything else?

[vasil-boshnyakov]

You have to modify the file:
/EFI/CLOVER/ACPI/patched/SSDT-3.aml

with MaciASL application. Just change the device ID, Save and restart

thanks, it's working
