Physics-enabled sprites are shaking when applying velocity

cocos2d-x C++
1

Hi,

I have a simple c++ class that inherited from Sprite. It has a PhysicsBody (using default physic engine). In the update method of this class i apply some velocity to it:

void PhysicsBody::update()
{
    ...
    Vec2 velocity;
    velocity.x = 0;
    velocity.y = 100;
    this->getPhysicsBody()->setVelocity(velocity);
    ...
}

When i use version 3.3 of cocos2d it has not any problem, but in v3.5 and v3.7 it is shaking a little!
When i use Box2D there is no problem.

I use Visual Studio 2013 and build project as win32 project.

Thanks…
