Mouse moves when axis move on joystick

[eddo888]

Description of Issue

I have a simple joystick configuration, I map an analog input to a joystick input. I am not including anything other than the joystick.h when I move the joystick axis, it moves the mouse

Technical Details

• Arduino Board = Arduino Leonardo
• Host OS = MacOS Mojave, 10.14.6
• Arduino IDE Version = 1.8.12

If I change the joystick type to "JOYSTICK_TYPE_JOYSTICK" the issue goes away.

Joystick_ Joystick(
  JOYSTICK_DEFAULT_REPORT_ID, 
  //JOYSTICK_TYPE_MULTI_AXIS,
  JOYSTICK_TYPE_JOYSTICK,
  32,
  0,
  true,  // Xaxis
  true,  // Yaxis
  true,  // Zaxis
  false, // rXaxis
  false, // rYaxis
  false, // rZaxis
  true,  // Rudder
  true,  // Throttle
  true,  // Accellerator
  false, // Brake
  false  // Steering
);

Looks like you found a solution to your issue, so I will close this. I have observed this behavior on Linux machines when the joystickType is set to JOYSTICK_TYPE_MULTI_AXIS as well.
