Looks like interior mode, does it do this with other render modes? Also, just becuase I have to ask, is DOF turned off in the camera settings?
The other option is to just start disconnecting nodes in the mat graph and see if anything changes. I'd remove the displacement first, and see if that fixes thing. Make sure your Photographic Styles are al turned off.
Basically you want to just start turning things off in a methodical way to track down what parameter is causing this.
