Bazzite releases unstable build with Mesa 26.2.6 and Gamescope 3.17.0 updates

The Bazzite project has published a new unstable release, version 45.20261110, providing updated packages for its SteamOS-like gaming environment. This pre-release build targets users testing the latest bleeding-edge software for gaming on Linux, including updates to the graphics stack and desktop environments.

Key updates in this iteration include significant version bumps for Mesa, Gamescope, and the Nvidia driver suite. The release also includes updates for both GNOME and KDE desktop environments, alongside improvements to container tools like Distrobox and Waydroid.

Technical component updates

• Graphics Stack: Updates Mesa to version 26.2.6-2 and provides new Nvidia Open (620.70.06-1) and Nvidia LTS (580.196.07-1) drivers.
• Gaming Compositor: Upgrades Gamescope to version 3.17.0^1-1 and the Gamescope Session to a git-based build.
• System & Containerization: Updates include Kernel 7.3.3-ogc1.1, Distrobox 1.8.2.5-2, Waydroid 1.6.3-2, and Waydroid (Nvidia) 0.1.2-3.
• Bug Fixes: Addresses an issue to ensure user services do not run on the GDM user via commit 5c3b32c.

Why it matters

As an atomic, gaming-focused Fedora derivative, these updates allow testers to validate the stability of the latest Mesa and Gamescope versions before they reach more stable Bazzite branches. This is critical for maintaining compatibility with Steam Deck-like handheld experiences and ensuring smooth Vulkan performance on both AMD and Nvidia hardware.
