Fixed in commit f170171.

proton::list_installed() now scans multiple locations instead of only the configured compat dir:

  • ~/.steam/root/compatibilitytools.d (ProtonUp-Qt default)
  • ~/.local/share/Steam/compatibilitytools.d (alternative Steam data dir)
  • /usr/share/steam/compatibilitytools.d (system-wide)
  • The configured proton_compat_dir from config

Versions are deduplicated by name (same version found in multiple paths only appears once), sorted newest-first, and shown in the settings pick_list in the GUI alongside the configured compat dir versions.
