The third weekly release candidate of Mesa 25.2 is now available for testing ahead of its planned stable release in August.
Mesa 25.2-rc3 brings an assortment of different fixes as outlined below. We’re working toward the Mesa 25.2 stable release in the coming weeks with its many new features in tow. As of writing there are just three open blocker bugs for the Mesa 25.2 release: two macOS issues have been reported and then the third is just ensuring good NVIDIA Blackwell support in the NVK driver. NVK has been baking its Blackwell support with the Linux 6.16+ Nouveau driver and is shaping up well there. We’ll see if any other blocker bugs materialize but for now at least it’s looking good to see Mesa 25.2 released as stable in the next week or two.
Some of the Mesa 25.2-rc3 changes include:
– A number of RADV Vulkan Video fixes such as around AV1 encode and VP9 decode.
– The Vulkan API conformance version has been bumped to v1.4.3 for the NVK NVIDIA Vulkan driver.
– Several Lavapipe fixes for software/CPU-based Vulkan driver implementation.
– RADV fixes a memory leak with the geometry shader (GS) copy shader NIR.
– Complete support for ARGB4444 within Mesa’s DRI code.
– Fixing a possible crash in LLVM for the RadeonSI driver.
