RobotArmApp example demo is visibly moving frame by frame at the end of each movement

• User clicks on a new pose
• RobotArm starts moving slowly
• RobotArm continues its move very fast
• RobotArm ends its movement very slowly, with the framerate being visibly on the low single-digit numbers.

Even if the end of the movement is slow, it should be smooth.

This happens on both raspberry pi and intel 620 embedded graphics.
