How to scale plane to fit screen

Sure, you can download the video file here!

I’m showing a plane with some random material on it, and I’m moving the camera with a VIVE controller. The plane is not a component of the camera, and its coordinates are calculated entirely on its own, according to the position and rotation of the camera.

As you can see, it shakes a lot, and especially in quick movements, the corners take some time to get filled. In addition, I tried moving the camera with the mouse, and the result was the same, so I believe it is not an issue with the VIVE controller.

I wonder if this kind of mesh update every frame is too heavy to be done…
