I wonder if this is caused by running everything over the same bus. Graphics is internally PCIe, which is what thunderbolt basically is, which is also routed through USB-C ports. And WiFi is probably an internal USB device. They probably don't have a separate controller for each port, so the throughput is limited. I wouldn't think video capture saturates the bandwidth already, but it probably messes with the timing enough that the WiFi driver gets confused. If it is really that, and not a mere software problem, then it should also show up when e.g. mixing external monitors and USB devices, or in other combinations. If that is the case, this would be really nasty. Edit: someone on twitter says it is probably RF interference https://twitter.com/jcenters/status/794273083469139968 https://twitter.com/jcenters/status/794273083469139968
