Ghost/Phantom Inputs in Emulationstation

[lexx]

Hey there!

A few weeks ago I switched to RecalBox and I absolutely love it so far.
I used some time lately to reorganize my library of games.

Before I had a little smaller library and ghost/phantom input just rarely happened. For example: When I scroll down the game list of a platform, it would just go on until I press another key.

Now that my library is bigger, it happens much more. Actually so often that I can't use my controller in Emulationstation anymore.

Here is what I use:
Raspberry Pi 3b
Asus BT 4.0 Dongle
2TB HDD
Sony Dual Shock 4
8bitdo NES30 Pro
Rii i8+ Keyboard

These input problems do not happen when I use the Rii i8+ Keyboard, which came with his own dongle.

It does happen with both Controllers. Doesn't make a difference if I use my BT Dongle or the onboard BT.

What I still need to try is if it happens when I use a cable connected to a controller.

What's the cause of the problem?
Since it only happens in the game list, I assume that the huge amount of scraped images are causing it(?)

Can you reduce it somehow? New/other Bluetooth dongle? Wait for the RecalBox Version for the 3b+?
Overclock higher than 1300Mhz?

Anything that could help is appreciated.

Thanks,
lexx

@lexx start evtest and check all input devices to see which one is sending ghost inputs. Have you enabled the gpio controls ?

@substring Thank you for answering.

I usually have only the PS4 controller paired. The 8bitdo is never being used. Only tried it out to see if I also have the problem with that one as well.

Only the Rii i8+ with his own dongle is connected and my PS4 controller over Bluetooth

I've tried the evtest just now. Here are two pictures.
Strange is that I see the keyboard twice. And the test itself was too fast to see any manual input from the controller. Edit: You can actually see one from me.

I did not enable gpio controls. Isn't that related to multiple arcade controllers? I'll look it up.

@lexx which controller generated all those outputs ? which number in [0-2] ?

[lexx]

@substring It was 2 - the Wireless Controller aka PS4.

Edit: Same happens with the 8bitdo NES30.
The pictures from the post above were with onboard Bluetooth enabled and no dongle connected.

I now disabled onboard Bluetooth and added my dongle. It works a bit better, but it's still hard to navigate through the Emulationstation menu. Still ghost inputs. Only the keyboard works flawlessly.

In-game everything is fine.

@lexx your pad looks like it's not calibrated as it's alays sending inputs

@substring Anything I can do about it?

Another edit: After thinking about it ...
That would be strange as it has no problems in games. At all. It's only happening in Emulationstation. Nowhere else.
I'm confused.

@lexx the gamepad is constantly moving of 1/256th, so most emulator that use digital inputs wouldn't notice it
