I have this warning on v4.2.1.stable.official, no sure if this is something of concern ?
InputManager.gd:288 @ _emit(): An input event object is being parsed more than once in the same frame, which is unsafe.
If you are generating events in a script, you have to instantiate a new event instead of sending the same one more than once, unless the original one was sent on an earlier frame.
You can call duplicate() on the event to get a new instance with identical values.
