<p>Way more easy then I initially thought – I was not aware that I can use CSS since it is the first time at all I work with GTK:</p>
<p>Add at the end of <em>Tools > Configuration Files > geany.css</em>:</p>
<pre><code>/* make search dialogs transparent if out of focus */
#GeanyDialogSearch:backdrop {
        background-color: transparent;
        opacity: 0.6;
}
</code></pre>
<p><strong>Note:</strong> <em>opacity</em> will only work together with <em>background-color: transparent</em> otherwise it will become black.</p>
