title: HomeAsUp icon showing a bit off
body: <p>I have this weird issue with the <code>getSupportActionBar().setDisplayHomeAsUpEnabled(true);</code> because it is showing the left arrow a bit off the layout. </p>
  
  <p>This is how the left icon looks </p>
  
  <p><img src="https://s30.postimg.org/s1axx8ump/11938904_970359143027460_1594648506_n.jpg" alt="left arrow"></p>
  
  <p>This is the code I use to set the <code>Toolbar</code> as the <code>SupportActionBar</code></p>
  
  <pre><code>Toolbar toolbar;
  ...
  toolbar = (Toolbar) findViewById(R.id.toolbar);
  setSupportActionBar(toolbar);
  getSupportActionBar().setDisplayHomeAsUpEnabled(true);
  </code></pre>
  
  <p>And this is the activity layout</p>
