ScreenCapture.CaptureScreenshotAsTexture() throws warnings

Does anyone has any idea how to get rid of these warnings?

Here is the code:

 private IEnumerator RecordFrame()
 {
     yield return new WaitForEndOfFrame();
     screenShot = ScreenCapture.CaptureScreenshotAsTexture();
 }
 StartCoroutine(RecordFrame());

And this code works but throws these warnings into the console:

Ignoring depth surface load action as it is memoryless
Ignoring depth surface store action as it is memoryless
