Dear Dylan, Timo, I'm the same person who submitted the Mesa 25.2.8 backport (#50). I now offer a fully tested backport of Mesa 25.3.3 (including security fixes up to 25.3.6) for trixie-backports.
Key adjustments for Trixie: - LLVM 21 → 19 - libdrm-dev >= 2.4.124-2 (instead of 2.4.125-1) - spirv-tools-dev → spirv-tools (>= 2025.1~rc1-1) - DirectX-Headers relaxed to >= 1.614.1 - Disabled native D3D12 driver (unused on Linux) Added patches for a Meson scope error and two CVEs (CVE-2026-40393). The backport compiles cleanly in Trixie amd64/i386 and has run stably on my Intel Arc B580 system for days (gaming and LLMs via vulkan). Due to the size of the [debdiff](https://stornic56hub.duckdns.org/git/stornic56/mesa-debian/raw/branch/main/debdiffs/mesa-v25.3.3/mesa_25.3.3-1~bpo13+1.debdiff) (~10MB, includes new source files for CVE patches), I have uploaded it to my [repository](https://stornic56hub.duckdns.org/git/stornic56/mesa-debian/releases/tag/v25.3.3). Please review, I'm willing to help maintain this backport. Thanks for your work. Best regards,
