I have about 15-20 Latitude 7350's deployed and almost all users are seeing issues on Teams calls, the other parties video may appear fragmented and green at times. They see us just fine but we cannot clearly make out other video, sometimes a shared screen or other times the face of the other party. Almost looks like a scene from the Matrix with green fragments. All video drivers are up to date as well as Windows updates. Same with updates through Dell command update program.
Most of the laptops are docked through a WD22TB4 Docking Station.
We also have several Latitude 9330's which have no issues with Teams video calls.
