Mesa 26.2.1 Released with A Large Collection of Bug Fixes

Mesa 3D graphics library released 26.2.1 version a few days ago, making the new 26.2 release series stable enough for production use.

Mesa announced 26.2.0 a few weeks ago with many exciting new features. Now, it’s ready for use by the first 26.2.1 bug fix update.

Mesa 26.2.0 is a new development release. People who are concerned with stability and reliability should stick with a previous release or wait for Mesa 26.2.1.

Mesa 26.2 updated its Rusticl OpenCL implementation with OpenCL 3.1 capability across Apple AGX, Intel, AMD, Vulkan-based, and CPU software backends. It introduced many new extensions support for AMD Radeon, Arm Mali, and PowerVR GPUs, as well as some improvements for NVIDIA and Intel GPUs support.

The new 26.2.1 release includes tons of fixes and improvements. For AMD GPU, it fixed a color-splitting artifact when playing YouTube AV1/VP9 videos with hardware decoding on RX 7900 XTX.

It also fixed 26.x regressions that HEVC/H.265 hardware decoding through VA-API stop working on Stoney Ridge AMD GPUs, and, H.264 hardware encoding through VA-API to produce corrupted recordings in gpu-screen-recorder.

It as well includes fixes for RadeonSI OpenGL and RADV Vulkan driver crashes, a rendering problem in Insurgency: Sandstorm where some geometry becomes black because of Z-fighting, and texture-filtering rendering bug in Wolfenstein II: The New Colossus.

On the Intel side, it fixed a regression for Intel Arc B70 GPUs that caused some llama.cpp unit tests to sometimes pass and sometimes fail, Intel GPU hang on certain Alder Lake-HX integrated GPUs when using OpenGL, and a bug how they handle vkCmdWaitEvents2.

For NVIDIA, it fixed the NVK driver for older NVIDIA Kepler GPUs can crash inside its shader compiler when running a wgpu application such as Zed.

Other changes include:

• Fix for a graphics-rendering problem in Witchfire.
• Firefox malfunction fix in Raspberry Pi 5.
• Fix AMD BC250 GPU detection.
• Add data integrity checks (CRC) support for for Arm GPUs using AFBC.

There are as well numerous other bug-fixes and improvements, see the official release note page for details.
