Mesa 26.2.5 Released With Fixes for RADV, RadeonSI, ANV, and Zink
Mesa 26.2.5 arrived today as the fifth minor update to the Mesa 26.2 stable series. The release polishes the NVK, Freedreno, RADV, RadeonSI, Zink, ANV, PVR, and PanVK drivers.
AMD Fixes in RADV and RadeonSI
The AMD stack drew the most attention in this release. RADV and RadeonSI now handle ray tracing more reliably. The fixes address black patches, texture artifacts, and load-dependent crashes.
Moreover, the AMD stack gained a floating-point precision fix for the video game No Man’s Sky. It applies when the game runs on the RADV Vulkan driver. Developers also fixed mesh shader state tracking issues and a race condition in the AMD kernel interface. Finally, they corrected ray-tracing data structure alignment for GFX12 hardware.
Intel ANV and the Jay Backend
On the Intel side, the ANV Vulkan driver received GPU synchronization fixes. These prevent hangs and incorrect results in timing workloads. A separate fix plugs a memory leak. Compute workloads were not cleaning up properly after a failure.
The Jay shader backend also got a small patch. It now skips work when there is none. This is a preview of Mesa 26.3, due later this year. That version will enable Jay by default and promises around 10% better runtime performance than the legacy BRW compiler.
Freedreno and Zink Updates
Freedreno also saw attention in this release. A fix targets a draw call issue on older Adreno A630-family GPUs. The bug caused crashes and visual glitches.
Zink received the most patches, with 27 in total. They improve frame presentation, fix memory leaks in the swapchain, and clean up invalid reads on teardown.
Smaller Changes
On top of that, Mesa 26.2.5 brings smaller fixes to the NVK, PVR, and PanVK drivers. Several texture-format codecs are now more portable across hardware architectures. In addition, Mesa’s internal NIR shader representation received a cleanup. For the full list, read the release announcement page.
How to Get Mesa 26.2.5
System integrators and people who compile software from source can download Mesa 26.2.5 from the official Mesa website. Everyone else should install the new release from the stable software repositories of their GNU/Linux distribution.
The next bugfix release, Mesa 26.2.6, is due on October 28.
