One detail in Mesa 26.1.3 captures where Linux graphics is heading: it fixes a RADV/ACO regression in Cyberpunk 2077 and, two lines down, a RADV NIR compiler infinite loop triggered by loading Gemma 4 via llama.cpp on a gfx1100 card. The same driver team now fields gaming and local-inference bugs in the same release. As local LLMs spread, should Mesa treat compute regressions with the same urgency as game-breaking ones?

Mesa 26.1.3, released June 18, is a bug-fix release implementing OpenGL 4.6 and Vulkan 1.4. The fixes are oddly specific: a RADV/ACO regression flashing reflections in Cyberpunk 2077, a RADV NIR compiler infinite loop when loading Gemma 4 via llama.cpp on gfx1100, an Intel ANV null-pointer dereference on DMA-BUF import on Xe2, and a radeonsi gallivm SIGSEGV during GL_FEEDBACK software fallback. Running a GPU compute or gaming workload on Mesa, which path do you hit?

New blog post: The Diagonal Seam 📐

Mesa's u_blitter copies pixels by drawing a textured quad - two triangles with a diagonal seam between them. For NEAREST filtering, that seam produces a stripe of wrong texels on GC7000, failing dEQP's nearest_consistency tests.

The proprietary Vivante blob doesn't draw a quad at all. It draws one oversized triangle and lets the scissor clip it. No seam, no problem.
