Sapphire R7 260x no animation and transparency

[wecler]

Hello all!

I'm new to hacks and I thought maybe someone here could help me with my problem. I have successfully installed Big Sur, although
I am having some issues with general system stability.

I have Big Sur 11.6.1 running on my hack and it works with everything except that the dock animations don't work and the transparency, i.e. the outlines of the application windows are black. I think the two screenshots can explain my case much better. It simply feels a little laggy. (At first I had problem that my mac showed 7 MB Display)

I should mention that I use OpenCore 7.4 and I've followed the official guide.

I've installed following kexts:
- Lilu
- WhateverGreen
- NVMeFix
- RealtekRTL8111
- SMCProcessor
- SMCSuperIO
- VirtualSMC
- WhateverGreen

I've tried changing my WhateverGreen version from 1.5.4 to 1.5.2 but it didn't worked.

I tried using no-gfx-spoof in mine device properties also without success and I have also tried following device-ids:

51660000 - AMD Radeon HD 8xxx 2GB
50660000 - AMD Radeon HD 8xxx 2GB
40660000 - AMD FirePro M6100 2GB

I've also added -raddvi radpg=15 to my boot-args.

My setup:
Big Sur 11.6.1 (iMac 15,1)
Processor: i5 4190 (Haswell)
Graphic: Sapphire R7 260x (I also have an GTX 660 and it worked oob although after some time using it artefacts appeared) - UEFI is supported
RAM: 16 GB 1333 MHz DDR3
Mainboard: Gigabyte GA-H81M-DS2
SSD: Samsung 256 GB 850 EVO

Does anyone have any idea how I can fix this problem?

I am grateful for any help!
Thank you very much!

Hello. Do you have 1GB GPU?

If this is the case, then you can flash VBIOS from 7790, but you need to carefully check that your version of video memory is in VBIOS from 7790.

Sorry for my English，I think you can try the method from << Solved >> - Radeon HD7730 QE/CI not active on Big Sur | tonymacx86.com
