While waiting at a red light for passengers to load/unload, strange graphical artifacts can be seen in the video attached below. I tried changing from DLSS, to FSR and none but it would not go away. The station in question was Warszawa Wschodnia, and it was at 2:02am at night. I was in the Pendolino.
