Updates Gamescope from 3.16.23.6 to 3.17.0 while preserving the project's NVIDIA support.
- Uses upstream capture color and texture-sampling fixes, replacing two patches previously carried by this project.
- Retains NVIDIA fixes for in-game menu composition, GBM scanout for 4K and HDR, and display-mode filtering.
- Reverts an upstream shared-output allocation change associated with graphical corruption in Big Picture on NVIDIA.
- Keeps the notification fix and MangoApp unchanged from 0.2.6.
Tested on the project's NVIDIA PC: notifications, Quick Access Menu over games, streaming in both directions, HDR, VRR, and switching between 4K and 1440p.
Installation through the Desktop Mode updater was verified. Version 0.2.7 and Gamescope 3.17.0 were also verified after updating SteamOS to 3.9.5.
Update an existing installation through SteamOS Installer Update in Desktop Mode and restart when prompted.
For a new installation, follow the project's instructions to build your own USB installation image using the official Valve recovery image.
