Some background videos are causing serious stream corruption

Here is the link to graph files and video files: h++ps://

The problem can be seen in the Action.mp4 video file in the folder linked above.
As soon as I switch from Cat-1.mp4 background video to 1.mp4 background video - both camera streams of the meeting attendees and the screen sharing becomes corrupted.

This also relevant to screen capture with AMD AMF when the webcam stream is captured from XSplit VCam with 1.mp4 video background.
I have several video files that are causing this bug, but I cannot figure out why is this happening.
