The Faugus Launcher, a game launcher for Linux to manage Wine and Proton games, has been released in version 2.5.7.

Just one day after version 2.5.6, the update brings a unique window class per game (fixes taskbar grouping and pinned shortcuts, which need to be re-created), a suggestion menu for the SteamGridDB asset picker, plus fixes for the sleep inhibitor, gamepad navigation and memory usage.

Additions / Changes

• Each game now has a unique window class. This fixes taskbar grouping. Games launched through another application, like WoW through Battle.net, will still be grouped together, as this is a Wine/Proton issue. It also fixes pinned shortcuts. Shortcuts need to be re-created to work.
• Added a suggestion menu to the SteamGridDB asset picker.
• Now skips the SteamGridDB asset fetch when the title entry loses focus while editing a game.

Fixes

• Fixed the sleep inhibitor not being released on game exit.
• Gamepad navigation is now locked by window focus instead of running games.
• Fixed retained memory after asset downloads and dialogs.

The following dependencies are required for the AppImage, as they cannot be bundled with it: pygobject gtk4 libadwaita libmanette
