No response

Expected Behavior

No response

Anything else?

After debug, I have found that this error is caused by the below code.

# Runtime/Scripts/InputPositionCorrector.cs
unsafe void PointerMap(StateEvent* data, InputDevice device)
        {
            switch (device)
            {
                case Mouse mouse:
                    MouseState* mouseState = (MouseState*)data->state;
                    mouseState->position = Map(mouseState->position, inputRegion, outputRegion);
                    break;
                case Touchscreen touch:
                    // todo(kazuki): multi touch is not supported yet.
                    TouchState* touchState = (TouchState*)data->state;
                    touchState->position = Map(touchState->position, inputRegion, outputRegion);
                    break;
            }
        }

The mouseState->position sometime will be (0, NAN)

Hope to fix in newer version, thanks
