- glMultiDrawArrays is broken. Workaround implemented and problem reported to AMD. No replies yet.<br>
[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
- 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.
**Vulkan.**
- Primitive restart is 'broken'. This seems to be a GCN hardware bug as it also affects mesa drivers to some extent. Workaround implemented. (confirmed - see [this commit](https://github.com/mesa3d/mesa/commit/eae8f49fc65e6e625f5e05d38c3bf1b61b84bd3d))
