This directory is the canonical source record for the patched Gamescope helper shipped by the launcher. The executable remains in the Python package because runtime lookup and installed paths are compatibility interfaces.

source.sha256 records the exact Ubuntu source archives. Obtain both archives without renaming them and place them in .artifacts/native/gamescope/sources/:

gamescope_3.16.20+ds.orig.tar.xz
gamescope_3.16.20+ds-1.debian.tar.xz

The patches are applied in this order:

gamescope-wayland-letterbox-backing.patch
gamescope-wayland-libdecor-input-scope.patch
gamescope-lazy-output-images.patch
gamescope-wayland-live-resize.patch
gamescope-keep-nested-windows-visible.patch

Build

Run the recipe from any directory:

./native/gamescope/build.sh

Pass a different source-archive directory as the first argument and an output directory as the second argument when needed. Set CONTAINER_ENGINE to select Docker or Podman explicitly. The recipe builds with dpkg-buildpackage in an Ubuntu 26.04 amd64 container, writes below .artifacts/ by default, and checks the result against binary.sha256. It refuses to write over the shipped helper. The container downloads build dependencies, so the Ubuntu 26.04 package repositories used at build time remain part of the build environment.

The files named gamescope-compat.README, gamescope-compat.copyright, and the five patches continue to be staged at their historical flat installed paths. The full Debian copyright record is retained in gamescope-compat.copyright.
