title: UWP InkCanvas differences between PC and Surface HUB
body: <p>Is there any difference in a UWP InkCanvas between a PC and a Surface Hub?</p>
  
  <p>I have deployed the same app package on both a PC and a Surface Hub. Everything works as expected on the PC. On the hub, the strokes have gaps when you draw a little faster. </p>
  
  <p>Here's a sample picture of a rectangle drawn fast on the hub: </p>

  <p>My InkCanvas is used inside a ScrollViewer for the Zoom and Pan functionality, like this: </p>
  
  <pre><code>    &lt;ScrollViewer BorderThickness="2" ZoomMode="Enabled" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" HorizontalScrollBarVisibility="Auto" ViewChanged="ScrollViewer_ViewChanged" &gt;
  
          &lt;InkCanvas x:Name="InkCanvas"  MinWidth="100000" MinHeight="100000" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Loaded="InkCanvas_Loaded" /&gt;
  
      &lt;/ScrollViewer&gt;
  </code></pre>
  
  <p>This is exactly the same app with exactly the same code. The app is using the Creators Update SDK. The Hub also has the Creators Update installed.</p>
  
  <p>I should also point out that I don't have a testing surface hub yet, this has been reported by my client, there's no easy way for me to debug this.</p>
