Hello. Thanks for reading my topic. I have updated Retroarch to current version1.17 using cores recent compiled. Ubuntu 20.04.6. PS4 DS4 controller using udev with udev permissions. Not is possible any other buttons inputs if holding the R3 stick button. I use the R3 for hotkey “fast forward” for some cores. However not is an issue with “fast forward” because if is mapped to keyboard space key is possible any input in controller.
I have tested disabling autoconfig input setting.
