title: OpenLayers map shows an extra tile on top of map
body: <p>I have an <code>Windows Phone 8</code> app made with <code>PhoneGap</code> framework to show a map of <code>OpenLayers</code>. Sometimes, although very rarely, I <strong>surf between views</strong> (<code>jQuery Mobile</code> is used) and suddenly when I am back on Map <strong>it shows an extra tile on the center of map</strong>. Tile is as wide as the map and starts some 20% before top and ends some 20% from bottom. It does disappear only when restarting the app.</p>
  
  <p>I am trying to show up the phenomenon on dev mode of Google on browser, but so far no success.</p>
  
  <p>No error is shown on console of wp8 sdk, I was testing it on device connected to visual studio.</p>
  
  <p><strong>What may cause that thing and could it be fixed somehow?</strong></p>
  
  <p><em><strong>edit1:</strong> It may be possible I trigger a swipe event while moving the screen fast and that may make the <code>Openlayers</code> in error state.</em></p>
