Mesa 25.2.6 released
Mesa, the free and open-source library for 3D graphics rendering, has released its latest version - Mesa 25.2.6. This release includes a variety of enhancements and bug fixes across multiple components.
In terms of Vulkan support, several key improvements have been made to improve performance and stability. A fix for integer dot product properties was contributed, along with the addition of features such as capturing and replaying buffer addresses for EDB capture/replay. Another significant improvement fixed invalid sparse bitfield offset computations and prevented modifications to LOAD_REG operations on MOV_INDIRECT/BROADCAST.
In addition to Vulkan enhancements, Mesa 25.2.6 includes a range of improvements to OpenGL support. For example, a fix was made for nir/shrink_stores, preventing stores from being shrunk to invalid components. Meanwhile, cl_local_size for precompiled shaders in the Panfrost driver was also fixed.
Radeon and RadeonSI drivers have also seen significant enhancements. Several key improvements were made to radv/video_enc, including cleaning up slice count asserts and overriding H265 SPS block size parameters. A fix was also contributed for the comparison of stride arrays when emitting vertex buffers in the R600 driver.
Other notable enhancements include the marking of fadd/ffma as nsz for fneg distribution, renaming rsqrtf() to _rsqrtf(), and mitigating a GPU hang on Hawaii in Dota 2 and RotTR by disabling compute queues.
Mesa 25.2.6 also includes various bug fixes and performance enhancements across multiple components. These improvements aim to enhance the overall graphics rendering experience for users of Mesa-based applications.
The release is available for download from the Mesa website, with a SHA256 hash of 361c97e8afa5fe20141c5362c5b489040751e12861c186a16c621a2fb182fc42 for the mesa-25.2.6.tar.xz file.
