There were similar issues like you said with the Radeon board that were covered by the recall; but if it was a hardware issue then why would so many people only have the problem after upgrading the OS? Still seems like there could be some solution with a firmware or driver update.
By disabling the AMD Radeon HD 6770 driver in the System, the graphic corruption and crashing have been eliminated. The display will not be as fast or fluid sometimes but it is still perfectly useable. I assume this just disables the Radeon GPU while still allowing the display function to operate. This fix is similar to what has been done on the Powerbooks which have this problem (although there you have an Intel GPU to use instead). To perform this fix:
Amd Radeon Hd 6770m Driver For Mac
Hopefully for any new/future game projects they use Vulkan as the primary graphics API. All major graphic vendors offer drivers with native Vulkan support for Windows and Linux and even many Android phones support it. Sony supports Mantel which formed the foundation of Vulkan and so likely also supports Vulkan in some form. Switch graphics being powered by NVidia also has native Vulkan support although some developers use the API Nvidia provided for Nintendo.
Only the Xbox One and Apple products do not natively support Vulkan. Technically the Xbox One can support it if Microsoft swallowed their pride and let AMD provide driver support for it, since it uses the same chips as the PS4 which almost certainly does in some form. Apple will never support native Vulkan but MoltenVK acts as an adapter between the Vulkan API and Metal which all Apple devices support. Hence a Vulkan backend can be made to run on Mac in a reasonable way. 2ff7e9595c
