Gives up gamescope's features (HDR handling, FSR, overlay; most `-steamos3` menus need gamescope). +## Plasma session with Big Picture started at login: works (2026-10-01, night) +- `~/.config/autostart/steamify-bigpicture.desktop` (`Exec=steam -gamepadui`) in the normal Plasma Wayland session, SDDM autologin set to + `plasma.desktop` (`pkexec /usr/lib/steamos/steam-set-session plasma.desktop`): Big Picture opens by itself, smooth, no artifacts, no + KWin environment variables needed.
