title: Rounded corners become edgy when scrolling listview
body: <p>I have a <code>ListView</code> in my Android app. The items have rounded corners defined like this:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;shape xmlns:android="http://schemas.android.com/apk/res/android"
  android:shape="rectangle"&gt;
  &lt;padding android:left="15dp" android:top="15dp" android:right="15dp"
      android:bottom="15dp" /&gt;
  &lt;solid android:color="@color/item_background" /&gt;
  &lt;corners android:radius="1dp" android:bottomLeftRadius="15dp"
      android:bottomRightRadius="15dp" android:topLeftRadius="15dp"
      android:topRightRadius="15dp" /&gt;
  &lt;/shape&gt;
  </code></pre>
  
  <p>When the <code>ListView</code> is displayed everything looks fine. But as soon as I start scrolling, the rounded corners get edgy and as soon as the scrolling stops they become rounded again.</p>
  
  <p>Any ideas?</p>
