Rendertexture to texture2d in Unity5

I used this method in Unity4 and the texture2ds came out fine:

 RenderTexture.active = screenshares[x];
                     screenshares2d[x].ReadPixels(new Rect(0, 0, screenshares2d[x].width, screenshares2d[x].height), 0, 0);
                     screenshares2d[x].Apply();

But after going to Unity5 the texture2ds turn out gibberish. Is there a newer way or old way to solve the same problem?
