Check Your Game Mode

Window Size Mod only affects non-fullscreen windows. If you're playing in fullscreen mode, the slider won't have any visible effect. Switch to windowed mode in your Video Settings first, then adjust the window size slider.

Verify the Slider Is Responding

Open Settings and locate the window size control. Move the slider and watch for any visual feedback or change in your window dimensions. If nothing happens:

  • Ensure the mod is properly installed and loaded
  • Check that you're adjusting the correct slider (not a different graphics setting)
  • Close and reopen the settings menu to refresh

Reset and Retry

If the slider appears stuck, try moving it to an extreme position (smallest or largest), then adjust it back to your desired size. Close the settings menu completely and give the game a moment to apply the change.

If problems persist, verify your game window isn't locked or constrained by your operating system's window management settings.
