Workaround implemented and problem reported to AMD. No replies yet.
[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. +- ~~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 **Vulkan.** - Primitive restart is 'broken'. This seems to be a GCN hardware bug as it also affects mesa drivers to some extent. Workaround implemented.
