title: FBSDKLoginButton weird background
body: <p>I'm trying to use the Facebook Login SDK and the <code>FBSDKLoginButton</code>. I initially used it on a white background but when I changed to a non-white background it exposed a very strange background image...</p>
  
  <p><a href="https://i.stack.imgur.com/3xPG9.png" rel="noreferrer"><img src="https://i.stack.imgur.com/3xPG9.png" alt="enter image description here"></a></p>
  
  <p>I'm not sure what I can change on it to hide that weird white background.</p>
  
  <p>Has anyone dealt with this? How can I hide that white stuff?</p>
  
  <p>Thanks</p>
