I installed bazzite today I didn't notice issue for about 4 reboots and until I had paired the second controller but not 100% without starting again to test
switch mode only, but you can put it in switch mode with the 2.4ghz dongle if you use a beta firmware that 8bitdo accidentally gave out and promptly removed because it had some issues they didnt like (like it turns off the controller when switching from xinput to switch input) i emailed them and asked about the feature and they said they are still working on it and hoping to get it into a stable release at some point
Easiest solution I think would be to buy a 8bit and use via 2.4ghz but rather use controllers I have and hold put on buying a new one in hope valve make a new steam controller
I'm willing to bet my issue is something to do with pairing 2 but I'd have to do a full new install to test that theory as if it is causing it seems unpairing one isn't enough to fix
I've tried googling if another else has my issue but only find people with issues in games with steam input and game natively seeing controller, I'm having issue with duplicate without even starting a game
Maybe not sure it's duplicating all inputs like pressing a send a a if I have my controller set to not use nintendo layout it really shots itself as duplicate is still using nontendo layout so pressing a sends a amd b so you can't do anything as it accepts and presses back at same time
i know steam has sometimes messed up the nintendo layout so you turn it off, next time you connect the controller its off in steam but still acts as if it is on
