there are lots of input problems with Retroarch – not sure anything will be done upstream. For example if triggering the hotkey to open the gui, it should not then assume X has been pressed to open the search. Gizmo has submitted a new working fix to remove the search box, so if you update retropie-setup and rebuild from source it will be gone. I will recompile some new binaries as soon as I’ve had a chance to test the latest retroarch.
