I can see through walls all of the time. How can I fix this?

[SeasickSquid57]

Hey guys. I've only been playing Soma for about twenty minutes. I just made it through the first part after getting the Omnitool thing. I crossed a bridge and made it into the room with the weird little robot/tissue hybrid thing and entered the first ventilation system you can crawl through in the game. As soon as I entered the vents I could see through all of the walls and couldn't see the interior of the vents or of any room I entered afterwards. How can I fix this? If I try reinstalling the game will I lose my save file? Thanks for any help.
