Left eye renders fine; right eye has the surface as fully opaque with yellow lines on it. Turning off stereo instancing fixes the problem, but also massively drops performance.

Here’s the material graph. Setting the opacity to 1 also “fixes” the issue, in that both eyes see an opaque surface, but then almost totally removes the point of using this shading model.

I have the same issue and really would like to use the single layer water with stereo instancing.

This is still not fixed in 5.4.4, sadly
