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.<\/p>\n

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.<\/p>\n

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.<\/i><\/p><\/blockquote>\n

<\/p>\n

Mesa 26.2<\/a> 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.<\/p>\n

\"\"<\/p>\n

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

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.<\/p>\n

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

On the Intel side, it fixed a regression for Intel Arc B70 GPUs that caused some llama.cpp<\/code> 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.<\/p>\n

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.<\/p>\n
