The ISS live feed uses the cameras of the HDEV experiment. This is a group of four cameras in a pressurized housing attached to the outside of the ISS.
The picture is from the forward-facing camera. What you're seeing in the top-left corner of the image image are a dust filament on the housing (red circle), what appears to be sunlight reflecting off a surface defect of the housing (green), and the edge of the housing itself (blue). The visibility varies with sun angle and brightness; they're not visible as I write this, but could be clearly seen shortly after the ISS came out of Earth's shadow.
