SDL2: RetroArch has to be restarted after Set All Controls in order for the controller to work

[davidhedlund]

Description

I am experiencing an issue with controller binding in RetroArch-AppImage when using SDL2. Here are the steps to reproduce the problem:

1. Delete all files in autoconfig/sdl2/.
2. Start RetroArch.
3. Navigate with the mouse since the fallback controller or keyboard will not work (see related bug: SDL2: Fallback controller not working with SDL2, and interupts the keyboard #13).
4. Go to Settings -> Input -> RetroPad Binds -> Port 1 Controls -> Set All Controls.
5. Bind the buttons as needed.
6. **Click on "Save Controller Profile".
7. You will not be able to navigate with the newly bound buttons.
8. Restart RetroArch.
9. The controller will work now.

Note

• This issue does not occur when using udev.
• This issue does not occur when using sdl2 with Flatpak.

Expected Behavior

The newly bound buttons should work immediately without needing to restart RetroArch.

Actual Behavior

The newly bound buttons do not work until RetroArch is restarted.

Environment

• RetroArch Version: 1.19.1

Additional Information

This issue seems to be specific to the AppImage version of RetroArch and does not occur when using udev or Flatpak with sdl2.
