In the dialogue with Gordon, the camera repeatedly captures the texture of the overlapping characters and Gordon himself.
Occurs after completing Gordon’s quest chain. It happened periodically before, but I couldn’t “catch” it. Video and log files
Update: The problem is with the camera itself. If you’re in a building with an open entrance (meaning the building isn’t a separate location), it can already capture the roof and display it during dialogue. Also, when interacting with objects, it highlights objects that are hidden from us but become visible during interaction. For example, bridges and trees (cut down).
