Bugfixes

25.3 -> 26.0

​https://gitlab.freedesktop.org/mesa/mesa/-/blob/26.0/docs/relnotes/26.0.0.rst

26.0.0 -> 26.0.1

• Missing Haswell case after a097a3d214eda7fb7b9ff63176754b7260e09e03 leads to bogus assert in intel_perf_mdapi.c
• Question: Does building Lavapipe on Windows require building "microsoft-experimental" as well?
• [ANV]: Regression in dxvk Greedfall
• [ANV][BMG] Building Mesa with Clang causes Missing Skin Textures in UE games - Tekken 8
• [ANV][DG2][Regression]: Flickering water "boxes" in Civilization VII
• [RADV] Killer7 has a blue tint with RDNA3/4
• [bisected] Xe3 regression with piglit tess/barrier-patch.shader_test after cmod prop change
• [radeonsi] Regression: GL_FEEDBACK returns 0.0 for X-coordinates (Legacy GL)
• anv, bisected: Genshin Impact wrong shadows, flickering grass
• turnip: llama.cpp: Running test-backend-ops results in segmentation fault
• venus crashes in vn_CreateDevice() with latest mesa/main [bisected]

The radeonsi regression fix is notable since we use Legacy GL.

[Bruce Dubbs]

Now version 26.0.2.

[zeckma]

Now 26.0.3.

[zeckma]

Now 26.0.4.

[Xi Ruoyao]

Just FYI with 26.0.{1,2,3} Zink caused frequent crash of GNOME shell on my system so I've switched back to the direct GL implementation (iris). Not checked 26.0.4 yet.

[zeckma]

Now 26.0.5. 26.1.0-rc1 has been released as well.

Replying to Xi Ruoyao:

Just FYI with 26.0.{1,2,3} Zink caused frequent crash of GNOME shell on my system so I've switched back to the direct GL implementation (iris). Not checked 26.0.4 yet.

Zink for me on my Intel system led to worse performance than the OpenGL driver. It didn't feel worth it at all to use it on that system.

[zeckma]

Now 26.0.6, and 26.1.0-rc3 has been released as well. We'll probably see 26.1.0 in two weeks.

[zeckma]

26.1.0 has been released. The plan is to update to 26.0.7 when it has been released, if it will be released. If not, then wait until 26.1.1.

[zeckma]

Now 26.0.7.

[zeckma]

26.1.1 has been released, but I'm thinking we should hold off on that, until this comes in.

In the mean time, I think I have a better scheme for handling Mesa updates.

Right now, the scheme is: 26.0.1 -> 26.0.7 -> 26.1.1 -> 26.1.<last>

The idea behind this was that the first bugfix release will give us a somewhat stable but good idea of what bugs are in the newest major/minor release.

I think we could still aim for that while creating a better user experience.

I think going for a scheme like 26.0.<middle> -> 26.0.<last> -> 26.1.<middle> -> 26.1.<last> is more stable, less chaotic, and still moderately gets us that idea I mentioned, of finding bugs.

Granted, all-in-all, it's up to the user what version they want to use. I'm mostly speaking about this since things can be a bit hectic from the last point release to the next major/minor and its bugfix, before going radio silent until the very last bugfix release.

• 26.0.1 fails to build: create_context.c: error: 'struct glx_screen' has no member named 'frontend_screen'
• A770: Counter-Strike 2 visual glitches (regression)
• Bisected regression: Assertion texObj->pt == view->texture failed.
• Kodi regression with panthor >= 1.7 after updating to Linux 7.0-rc1
• MDK2 HD (opengl) has most elements rendered as black
• Mesa 25.3 amdgpu memory issue
• OpenGL 4.1 VRAM Memory Leak with setting uniform variables
• Panfrost Bifrost compiler assertion failure: wrong vectorization in bi_alu_src_index (Mesa 26.0.0)
• RADV: RDNA4 visual corruption in DX11 (DXVK) – Mafia III character model glitches, AMDVLK renders correctly (9070XT)
• [radeonsi] Regression: GL_FEEDBACK returns 0.0 for X-coordinates (Legacy GL)
• glsl: spec@glsl-es-1.00@linker@glsl-mismatched-uniform-precision-unused broken
• ir3: ir3_get_predicate() vs &ctx->build
• r300 , regression , bisected : Glitches with Sauerbraten

• Portal hard locks the machine on rv350.
• Turnip crash with lazy depth textures: GPUMEM_BIND_RANGES failed (Not a typewriter)
• [regression] Left 4 Dead 2 crashing when joining or starting survival with "Official Dedicated" servers
• lavapipe: crash in caselist
• zink: mesh shaders broken
• Accumulation of black squares with OpenGL applications at high resolutions (hiz-related)
• RADV: Invalid hitAttributeEXT value when using function-call RT pipelines
• Segmentation fault in gm200_validate_sample_locations with Firefox on GTX 1070 Ti (nouveau)
• Vulkan CTS regression bisected to 5d2c17a5fdce ("vtn: skip make-available/visible for shared")
• [anv] Intel ARC B390 | Horizon Forbidden West | DX12 | Flashing effects
• [radeonsi] Missing ground texture in Lethis Path of the Progress
• amdgpu reset/crash when simulating stereo camera
• building mesa_clc on ubutu-26.04 with gcc-16 fails link
• util: Build regression with MSYS2 MinGW-W64 x64 clang 21 on 26.0.0-rc3
• wsi: assert(chain->dxgi); may failed under venus for win32
• Is maxFragmentCombinedOutputResources=16 in Honeykrisp reflects an actual HW limit?
• Mesa LLVMpipe Memory Leak
• glcpp: incorrect macro expansion in token pasting
• nir: possible exactness bug in reassociate

There's a couple of memory leaks and memory management, but I'm not marking them as security issues since they seem to be moreso regressions than security issues. Users would still face them at run time, though.
