Bazzite 44.20261026 stable updates Gamescope to 3.17, kernel to 7.2.11-ogc4

Bazzite has shipped stable release 44.20261026, advancing its custom gaming kernel from 7.2.9-ogc3.1 to 7.2.11-ogc4 and upgrading Gamescope from 3.16.31 to 3.17.0. The release also refreshes Mesa to 26.2.4, InputPlumber to 0.83.0, OpenGamepadUI to 0.46.1, and UMU Launcher to 1.4.4, alongside Nvidia driver updates for both open and LTS branches.

This is a routine but substantial stable update for the Fedora-based SteamOS alternative, touching the full stack from kernel through display compositor to user-space compatibility tools. Users on Deck, desktop, and Nvidia variants all receive package refreshes, with specific image flavors seeing additional updates like PipeWire filter-chain modules and desktop background packages.

Kernel, graphics stack, and gaming layer changes

• Kernel: Updated to 7.2.11-ogc4 from 7.2.9-ogc3.1 on the main branch; Nvidia LTS remains at 6.18.56-ogc1.1 with driver version 580.178.04-2.
• Gamescope: Bumped to 3.17.0^1-1 from 3.16.31^6-1, bringing Valve's latest Wayland compositor improvements for HDR, VRR, and nested session handling.
• Mesa: Ships 26.2.4-1 for open-source Vulkan and OpenGL drivers across AMD, Intel, and NVK paths.
• Input and controller stack: InputPlumber 0.83.0-2, OpenGamepadUI 0.46.1-8, and hid-fanatecff/hid-tmff2 driver updates refine wheel and gamepad support.
• Proton/Steam compatibility: UMU Launcher 1.4.4-1 and SteamOS-Manager 0~20261018.gitaa85e5b-1 keep the non-Steam and Steam Deck UI compatibility layers current.

Why it matters

For Linux gamers running Bazzite on Steam Deck, living-room PCs, or handhelds, this stable release tightens the feedback loop between Valve's upstream SteamOS components and a Fedora-based immutable system. The Gamescope 3.17 bump specifically matters for anyone relying on HDR output or variable refresh rate on external displays, while the kernel and Mesa refresh keeps hardware enablement aligned with AMD and Intel GPU developments.
