Disabling horizontal scrollbar in IntelliJ IDEA nav popups
<p>Whenever I use the navigation pop-up (ie, the "Go To File" modal) in IntelliJ IDEA, there's a horizontal scrollbar that shows up sometimes, which hides the last result, or hides the only result:</p>

<p><a href="https://i.stack.imgur.com/8hezy.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8hezy.png" alt="Go To File"></a></p>

<p>Is there any way to hide this scrollbar? In a practical sense, I can of course tell that it's probably found the correct file, and worst case I just go to the wrong file. Just a minor annoyance, really.</p>

<p>Note: I'm using IntelliJ IDEA 15.0.2 under Ubuntu 14.04, using the Unity windows manager. This doesn't happen in the OSX version.</p>
