The latest Mesa 3D graphics driver now is available to install via PPA in Ubuntu 18.04, and Ubuntu 18.10.

- format_types.h:1220: undefined reference to `_mm256_cvtps_ph’
- glLinkProgram locks up for ~30 seconds
- [RADV] The Witcher 3 system freeze
- Mesa 18.3.2 crash on a specific fragment shader (assert triggered).
