<p dir="auto">When hardware acceleration is enabled (OS X 10.10.1, Atom 0.165.0), rendering artifacts occur when text clips behind the vertical scrollbar in the file pane. I've included a GIF animation that demonstrates the problem. I've noticed it doesn't always occur. For example, if I have the setting page open and active, I don't get the artifacts when sliding the file pane.</p>
