My team encounters this problem on every robot we make. We usually blame gearboxes and chains and forget a mechanical fix for it. The best way to augment the drive control is to place a gyro on the robot. While this is not a direct fix for the problem it treats the symptoms. The gyro detects the direction the robot is moving, compares it to the command from the joystick, and corrects the difference. The mecanum drive block has a place for a gyro input. All you have to do is pop the gyro on the bot (dead center) and connect it to the block.
