[NOTE] This seems to be undefined behavior in the spec. The gl_VertexID propagation behavior across MultiDrawArrays is not defined, i.e whether it should continue incrementing of reset to 0 on a new instance. However, due to the comparison with a loop of [first, count] and implied functional equivalence, this may be interpreted as a bug. Either way, RPCS3 provides a workaround using index lookups.

- ~~glGetTexImage/glGetTextureImage/glGetTextureImageEXT do not work with immutable textures if pack/unpack byteswap is requested. Workaround implemented.~~ Fixed in driver version 19.4.3 - ~~glGetTexImage/glGetTextureImage/glGetTextureImageEXT do not work with immutable textures if pack/unpack byteswap is requested.

- ~~Critical bug with Adrenalin 2020 drivers (since 19.12.x series). OpenGL no longer works with proprietary AMD drivers. Issue reported to AMD, we're waiting for action from their side.~~ Fixed in driver version 20.1.4 - ~~Critical bug with Adrenalin 2020 drivers (since 19.12.x series).

- Primitive restart is 'broken'. This seems to be a GCN hardware bug as it also affects proprietary drivers. Workaround implemented.

- LLVM8 codegen is broken. Use mesa with LLVM9 codegen to avoid this issue. Padoka PPA has the updated LLVM9 drivers for ubuntu users.

- If using the experimental Southern Islands amdgpu support, enabling MSAA may cause the emulator to crash. This is a limitation of the driver, disable MSAA to work around this issue. - If using the experimental Southern Islands amdgpu support, enabling MSAA may cause the emulator to crash.
