This pre-release contains a preview of zink driver, see #30.

Known issues

libvulkan-1.dll error

This error can occur even if you don't select zink driver via SET GALLIUM_DRIVER=zink, see this bug report for more information.

How to fix

1. Download and install Vulkan runtime. Note; You may already have this if your computer supports Vulkan graphics as it comes bundled in graphics drivers. Though updating it separately won't hurt.

2. Run fix-libvulkan-1.dll-missing-error.cmd from release package and apply offered hotfix. This tool helps Mesa3D use Vulkan runtime by forwarding calls to libvulkan-1.dll down to vulkan-1.dll. This tool also verifies if Vulkan runtime is installed in the first place.

32-bit is busted

opengl32.dll crashes and takes any program down with it. This issue has been reported upstream.
