Improve Exit Transition from Pause Screen

📋 Summary

Improve the transition when exiting a game from the Pause Screen so the emulator does not briefly flash back on screen before the shutdown theme or LaunchBox/Big Box returns.

❗ Problem

When selecting Exit Game from the Pause Screen, the screen can briefly flash back to the running game or emulator before the shutdown/game-over theme appears.

In some cases, users may also see a blank emulator window or other emulator closing visuals.

This makes the exit transition feel unpolished, especially in Big Box setups where startup, pause, and shutdown themes are intended to hide emulator behavior.

💡 Proposal

Keep a LaunchBox/Big Box controlled overlay visible during the entire exit flow from the Pause Screen.

When the user chooses Exit Game:

• The game should remain hidden immediately

• The shutdown/game-over theme should appear without exposing the emulator

• If shutdown themes are disabled, LaunchBox or Big Box should return cleanly without showing the emulator closing process

• Emulator closing windows or blank flashes should be masked where possible

🧩 Use Cases

• Exiting an emulator from the Pause Screen in Big Box

• Arcade cabinet setups where emulator windows should never be visible

• Themes that rely on smooth startup, pause, and shutdown transitions

• Emulators that briefly show blank or intermediate windows while closing

📦 Benefits

• Makes game exits feel smoother and more polished

• Better hides emulator behavior from the user

• Improves the Big Box arcade/couch experience

• Makes pause and shutdown themes feel more cohesive

⚠️ Considerations

Some emulators and fullscreen modes may still limit what LaunchBox can fully control, especially during process shutdown. The goal should be to improve masking and handoff behavior wherever possible, while preserving reliable emulator exit commands.
