Bazzite unstable updates to Linux 7.3.4-ogc4, reverts Framework panel replay fix

Bazzite, the Universal Blue-based SteamOS-compatible gaming distribution, has published unstable build 45.20261114.1 with a kernel bump to 7.3.4-ogc4.1 alongside its existing NVIDIA LTS kernel at 6.18.60-ogc1.2. The release reverts a prior commit that removed a panel replay workaround for Framework laptops, suggesting the fix introduced regressions or remains incomplete with the newer kernel. The update also expands the Bazaar curated application list to include Epic Games Launcher.

This unstable build carries Mesa 26.2.6-2, Gamescope 3.17.0, MangoHUD 0.8.4-2, UMU Launcher 1.4.4-1, and SteamOS-Manager from late October 2026. Desktop environment versions include GNOME 51.1 and KDE Plasma 6.8.2. NVIDIA users receive either the open driver at 620.70.06 or the LTS proprietary driver at 580.196.07, with Waydroid split into standard and NVIDIA-specific variants.

Kernel, graphics stack, and handheld-specific changes

• Kernel update: The main kernel advances from 7.3.4-ogc3.1 to 7.3.4-ogc4.1, while the NVIDIA LTS kernel remains at 6.18.60-ogc1.2, indicating continued dual-kernel support for different hardware configurations.
• Framework laptop regression: Commit 5644914 reverts the removal of a panel replay workaround, implying the original fix for display power management on Framework hardware was not stable enough for general use with the updated kernel.
• Gaming tools stack: Gamescope 3.17.0^1-1, MangoHUD 0.8.4-2, OpenGamepadUI 0.46.1-8, InputPlumber, and UMU Launcher 1.4.4-1 are all present, maintaining Bazzite's focus on Steam Deck-like handheld and controller-oriented gaming.
• Bazaar expansion: Epic Games Launcher joins the curated list in Bazaar 0.9.4-5, broadening non-Steam game store support without manual installation.
• Intel graphics updates: intel-igc moves to 2.41.16-1 and intel-opencl to 26.35.39758.21-2, bringing newer Intel graphics compiler and OpenCL runtime components.

Why it matters

For Linux handheld and living-room PC users, Bazzite's unstable channel serves as an early testing ground for kernel and gaming stack changes that may eventually reach the stable branch used by Steam Deck-like devices. The reverted Framework panel replay workaround highlights the ongoing difficulty of maintaining display power management fixes across kernel versions for emerging open-hardware laptop platforms. The Epic Games Launcher addition in Bazaar reflects continued pressure on Linux gaming distributions to support multiple storefronts beyond Steam, particularly as anti-cheat compatibility and Proton improvements make more titles viable.
