Mesa 19.1.4 is now available with fixes for hair oddities in Max Payne 3 on AMD/RADV
The latest version of the graphics library which underpins all GNU/Linux graphics when free drivers are used has a lot of other fixes for Radeon graphics cards. There's also fixes for nv50 and nvc0 based NVidia cards in the free nouveau driver and some fixes for Intel integrated graphics.
Games like SuperTuxKart render their graphics using the Mesa 3d graphics library.
There's also fixes for the spirv, nir and egl backends. This is a minor bug-fix release, the bigger features like AMD Navi support will come when Mesa 19.2 is released. The first release candidate for 19.2 should have been out yesterday according to their total plan for Mesa 19.2. It has been delayed. Mesa developer Emil Velikov has announced that "With multiple teams finalising the final features for their drivers, I've decided to push the branch point by one week." Mesa 19.2 rc2 is scheduled for August 13th which indicates that rc1 will be available on that date.
The Mesa team high-lights these fixes in Mesa 19.1.4:
- A fix for hair artifacts in Max Payne 3 on AMD/RADV.
- Vulkan 24/48 bit formats are now not supported on Ivybridge.
- R8G8B8_UNORM_SRGB is not supported on Haswell.
- Vulkan transform feedback extension is disabled on Intel gen7.

- nir: Allow qualifiers on copy_deref and image instructions
- st/nir: fix arb fragment stage conversion
- nir: don't return void
