We’ll start with Mesa 12.0.6, which appears to be an extra, but also the last point release to the 12.0 stable branch, patching a CSO (Combined Sewer Overflow) issue that could lead to lockups of the graphics processing unit (GPU), as well as other unforeseen performance of the Gallium graphics drivers. From the release announcement, it would appear that Mesa 12.0.6 fixes a total of 43 bugs discovered lately in the RadeonSI, Intel i965, and Nouveau open-source graphics drivers, along with the Intel (ANV) Vulkan driver, the GLX DRI3 GPU offloading support, and NIR, the new IR (internal representation) for the Mesa shader compiler.
