Sorry to hear that. Can you provide details on your setup and maybe the command line output?
I tested it mainly on Linux, but a quick test on Windows also looked fine.
I usually play horror games in batches. And this one displayed wrong in the same way for me. Which makes it unlikely to be an external issue. To be honest, for a second it made me panic that a graphic driver somehow corrupted until I went back and tested one of your previous games which also run on the same engine. It looked fine, unlike Offshore.
Well, it is still possible... seeing you already conducted tests. I just can't be sure what.
