FrontWars players running the Steam desktop client may encounter bugs when playing in fullscreen, most notably ghost duplicate windows appearing when pressing Alt+Tab. Developers Phoenix and VexxusArts have deployed client patches to address window management, background processes, and overlay interference.

The Alt-Tab Duplicate Instance Bug

On Windows systems, playing FrontWars in fullscreen previously caused extra game instances to spawn inside the Alt+Tab window switcher and Windows Task View whenever players tabbed out.

Key characteristics of this issue reported on the Steam Community forums include:

  • Tabbing away from fullscreen generated phantom duplicate windows that could be cycled through using Alt+Tab.
  • Closing the visible game client often failed to eliminate the phantom entries.
  • The ghost instances did not display corresponding processes inside Windows Task Manager, leaving players unable to force-close them manually.

Official Patches and Fixes

The development team addressed window management problems across two major desktop client updates.

Desktop Client Update 0.1.7 Fixes

Update 0.1.7 directly targeted the Alt+Tab fullscreen glitch alongside keybind conflicts:

  • Disabled Steam Overlay on Windows: The Steam overlay has been turned off by default on Windows to stop duplicate window instances from piling up in Alt+Tab and Task View.
  • Shortcut Interception: Fixed keyboard inputs like Ctrl+W, Ctrl+R, and Ctrl+Plus/Minus accidentally closing, reloading, or altering the zoom level of the client during matches.
  • Window Startup Fix: Addressed a bug where the client display window would occasionally fail to appear upon launch.
  • Crash Recovery: If the client crashes multiple consecutive times, it displays an error screen with a "Retry" prompt instead of looping through continuous restarts.

Wrapper 0.1.5 / Update 41.6 Adjustments

Earlier improvements deployed in Update 41.6 resolved hidden background tasks:

  • Full Exit on Close: Pressing Alt+F4 or clicking the window close button now terminates the process completely, preventing Steam from incorrectly showing the game as still running.
  • Startup Reliability: Resolved failures when starting a session after a previous improper shutdown or when opening the game via a desktop shortcut.
  • Steam Deck & Linux Handling: Addressed startup failures in Steam Deck Game Mode and defaulted controller inputs to a keyboard-and-mouse profile.

Troubleshooting Checklist for Fullscreen Problems

If you encounter input freezes, ghost windows, or black screens while running FrontWars in fullscreen mode, follow these verified resolution steps:

  1. Verify Client Version: Ensure the Steam client has downloaded Desktop Client Update 0.1.7 or later so the overlay disablement and window pooling fixes are active.
  2. Close via Standard Exit: Use Alt+F4 or the standard window close button rather than terminating tasks abruptly, allowing the 0.1.5 exit routines to clear the session cleanly.
  3. Switch to Web Browser Play: Because FrontWars shares unified servers between the Steam build and the web version at frontwars.io, players experiencing persistent client window errors can access matches directly in a browser.

Frequently Asked Questions

Why does FrontWars keep showing duplicate icons in Alt+Tab?

In earlier client versions, tabbing out of fullscreen mode created phantom instance hooks inside Windows Task View. Developer patch 0.1.7 disabled the Steam overlay on Windows to prevent these ghost instances from generating.

Does closing FrontWars leave hidden processes in Task Manager?

Prior to client update 0.1.5, closing the game could leave background tasks active, causing Steam to register the game as running. This was resolved so that closing the window fully terminates the application.

Why is the Steam overlay unavailable in FrontWars?

The developers intentionally disabled the Steam overlay on Windows in Desktop Client Update 0.1.7 to resolve critical window duplication and task management glitches during fullscreen gameplay.
