 - Primitive restart is 'broken'. This seems to be a GCN hardware bug as it also affects proprietary drivers. Workaround implemented. (confirmed - see [this commit](https://github.com/mesa3d/mesa/commit/eae8f49fc65e6e625f5e05d38c3bf1b61b84bd3d))
 - ~~LLVM8 codegen is broken. Use mesa with LLVM9 codegen to avoid this issue. Padoka PPA has the updated LLVM9 drivers for ubuntu users. See [this bug report.](https://bugs.freedesktop.org/show_bug.cgi?id=110970)~~ Fixed in newer versions of mesa based on later LLVM versions.
 - 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.
