title: C# WPF: Blurred Text
body: <p>I am new to C# WPF and working on somebody else's code.
  (WPF version 3.0.6920.5011, as read from <code>HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.0\Setup\Windows Presentation Foundation</code>)</p>
  
  <p>I already gave a look to various (quite old) Stackoverflow solutions, but they don't seem related to this problem: <a href="https://stackoverflow.com/questions/190344/wpf-blurry-fonts-issue-solutions">WPF Blurry fonts issue- Solutions</a>, <a href="https://stackoverflow.com/questions/22953901/text-is-blurred-when-transformed-in-wpf">Text is blurred when transformed in WPF</a>. </p>
  
  <p><a href="https://stackoverflow.com/questions/6436501/wpf-why-does-text-and-elements-blur-if-i-use-dropshadow-effect-on-a-parent-item">WPF: Why does text and elements blur if I use dropshadow effect on a parent item</a> looks interesting, but there are no shadows applied to parents.</p>
  
  <p>I observe this "blur" effect whenever an element is included in another one, and it is more and more visible as the inclusion goes deeper:</p>
  
  <ul>
  <li><strong>Device</strong> tab's text is perfectly readable</li>
  <li><strong>Global</strong>, <strong>Common</strong> and <strong>Inputs</strong> tabs' texts are lightly blurred</li>
  <li>Pane inside <strong>Inputs</strong> is highly blurred.</li>
  </ul>

  <p>Alas I cannot provide XAML files because of company rules, but there are no settings about ClearType, applied shadows nor to blur effects.</p>
  
  <p>Is there anything else I could check? 
  Thank you in advance</p>
