NEXT (Proton) — REQUIRED, or the loader is ignored and the fix won't apply in gameplay.
  Steam > right-click ${TITLE:-$GAME} > Properties > Launch Options:
      ${LAUNCH_OPTION:-WINEDLLOVERRIDES="${LOADER%.dll}=n,b" %command%}

  Then set the in-game resolution to your native ultrawide res, fullscreen.

Tuning (METHOD=bepinex games):
  Config is generated on first launch at
      <game>/BepInEx/config/*.cfg      (edits apply live, ~2s, no restart)
  Plugin log (proves whether it applied):
      <game>/BepInEx/LogOutput.log

Troubleshooting:
  Different loader name:  LOADER_NAME=version.dll ./install.sh $GAME
  Diagnose injection:     add PROTON_LOG=1 to launch options, then
                          ./tools/read_protonlog.sh $APPID
  Remove everything:      ./install.sh $GAME uninstall
