I looked into this some more and thep3000 is right, it was just a projection matrix problem. The solution is simple – when you render to a render texture, set your camera’s projection matrix to be the vive’s projection matrix. Query the device and then if Vive is detected, assign the projection matrix as shown in this thread:

The only thing I did differently was using namespace Valve.VR and then calling:

OpenVR.System.GetProjectionMatrix(vrEye, mainCamera.nearClipPlane, mainCamera.farClipPlane, EGraphicsAPIConvention.API_DirectX)

     private IEnumerator TakeScreenShot()

             yield return new WaitForEndOfFrame();
     
             RenderTexture rt = new RenderTexture(resWidth, resHeight, 24);
             _camera.targetTexture = rt;
             _screenShot= new Texture2D(resWidth, resHeight, TextureFormat.RGB24, false);
             _camera.Render();
             RenderTexture.active = rt;
             _screenShot.ReadPixels(new Rect(0, 0, resWidth, resHeight), 0, 0);
             _camera.targetTexture = null;
             RenderTexture.active = null;
             Destroy(rt);
     
             string filename = ScreenShotName(resWidth, resHeight);
     
             //byte[] bytes = _screenShot.EncodeToPNG();
             //System.IO.File.WriteAllBytes(filename, bytes);
 
             Debug.Log(string.Format("Took screenshot to: {0}", filename));
     
             Sprite tempSprite = Sprite.Create(_screenShot,new Rect(0,0,resWidth,resHeight),new Vector2(0,0));
             GameObject.Find("SpriteObject").GetComponent<SpriteRenderer>().sprite = tempSprite;
         }
