Big Box loses focus after exiting emulator Duckstation and PCSX2

[Tempest]

This behavior happens with DuckStation, in this particular case. I load the game from Big Box and when exiting the game using the pause menu from Duckstation, Big Box loses focus and I need to alt+ab to gain focus again. Basically, BB freezes and the video snap does not load until I alt+tab to focus. DuckStation starts in fullscreen and with -batch in command-line options.

I did not observe this behavior when exiting Retroarch, for example. One way to circumvent this is to assign a hotkey to the controller or keyboard to close the active window. However, I would prefer to exit using the emulator menu.

Has anyone experienced this? Is this normal behavior from Big Box when using other emulators rather than Retroarch?

Unfortunately it is a known and never solved problem that occurs differently on various systems, devices, games or emulators, in short it depends a bit on a million different conditions. For example Duckstation does not give me this problem, while it happens to me for other emulators.
To solve the problem safely I usually create an external autohotkey script similar to this:

WinWait, ahk_exe duckstation-qt-x64-ReleaseLTCG-MSVC.exe
WinWaitClose, ahk_exe duckstation-qt-x64-ReleaseLTCG-MSVC.exe
WinMaximize, LaunchBox
WinRestore, LaunchBox
WinActivate, LaunchBox
WinMaximize, BigBox
WinRestore, BigBox
WinActivate, BigBox

 

replace this "duckstation-qt-x64-ReleaseLTCG-MSVC.exe" with the one for your version of duckstation
