Keyboard and PS4 Controller Inputs conflict.

[frostlove]

Godot version:

3.3

OS/device including version:

Windows 7

Issue description:

When PS4 Controller is plugged in Dpad/Keyboard directional inputs aren't responsive. The arrow keys move sprite only for a little while before stopping completely. PS4 input on the other hand continues to move flawlessly. Changing Deadzones doesn't fix issue.

Steps to reproduce:

• Created a sprite2d node.
• Moved it around by changing global_position coordinates. Used Input.is_action_pressed functions.
• Used input mapper in the Project Settings tab.
• Keyboard works perfectly if I unplug the ps4 controller.

Can you reproduce this on the Joypads Demo or other games/applications? Can you reproduce this on Godot 3.2.3?

I got the same results on 3.2.3. Although it took a little longer for the keyboard input to stop on 3.2.3 than on 3.3. It doesn't seem to happen as often in 3.2.3.
I'm had this problem with pretty much every project I've tried so far. About 3 or so.
I recreated the demo I uploaded within Tte joypads demo and got the same result for every other project I did.

a small difference between the 3.2.3 and 3.3
3.2.3: The problem only happens after I hold down the left analog stick then release.
3.3: The problem happens whenever the ps4 controller is plugged into the PC.

*After experimenting some more I found out that even lightly touching the left analog stick stops the keyboard movement. But this happens regardless of the deadzone level. I've set the deadzone to 1.0 in the project settings but the problem still happens.
And by lightly touching I mean just barely touching it. Like 1-2% of the way down. I've tried setting the deadzone in gdscript so it could change during runtime but no luck there either.

@frostlove Thanks for the reply. Can you test this on all older 3.3 RCs and betas to determine when the regression started? You can download them here and here (3.2.4 was renamed to 3.3 during the development process).

Okay so Godot v3.2.4 beta1 is the earliest version that doesn't cause the PS4 plug in issue. But the lightly touching the left analog stick issue is still there (despite the deadzone). But I can still move the sprite around with the PS4 controller plugged in using the keyboard or controller.

edit-
I tested the deadzone issue all the way down to RC1 3.2.1 but it was still present.

A player of mine is running into a similar issue, their ps4 left/right input is randomly not working every few minutes. I haven't been able to reproduce the issue myself but here is a video that they took:

Closing as a duplicate of #45628.
The Input Map settings of the MRP show that keys, buttons and axes are mapped to the same action:
