Kinect Azure Pointcloud and Kinect Azure Color don't match

Hey. I want to build the classic kinect pointcloud system with colors as plenty of us have made before. However I came up with difficulties at the very beginning.
Kinect Azure Top works fine, but whenever I add Kinect Azure Select Top, pointcloud slows down; there is a visible lag. Therefore when I combine both inputs they don’t match.
I have this issue on two different machines. I checked two different USB cables. I haven’t checked different sensor yet. I’m using orbec, not original Azure.
Has it occurred to anyone?
