I just encountered a very strange bug, any object place on the surface of the water, or submerged will have weird texture distortion as the camera is on the very surface of the water and then placing the camera underwater will generate black boxes all around the shape of the object, no matter if it is fully in water or not.
Normal, few inches above water
Texture distortion just an inch from the water
Underwater
And also in some areas the sea floor seems to be missing as soon as you hit the water-
Another view-
And finally it seems that this may be a bug too, anything under any depth will appear too visible, and not appear like its underwater in some angles.
Sorry if some of these bugs are known already, I searched around but wasn't able to find any similar posts. The black squares underwater are the most jarring though, they happen in any underwater situation whether normal or with the bottom mesh missing like here again
I made sure I wasn't running any programs in the background that could be interfering with the game somehow like MSI afterburner etc, made no difference.
