Left eye seems fine, right eye you can see how the green-ness is only covering half the water.
Whatever this is, it actually moves around in the right eye like it’s a green plane filling the water area, but when I move my head the ‘plane’ moves with me.
I’ve been seeing a similar issue exclusive to the right-eye. The material on the plane seems to warp and move around as the HMD turns and moves around.
I’ve also experienced odd instances where reflections and lights did not render properly in the right-eye. I have not tracked down what the cause is yet sadly
