title: Gimp - jagged pencil and brush strokes
body: <p>I am using Gimp 2.8.14 on Ubuntu 14.04 and a Wacom tablet (Intuos 3 6x8).</p>
  
  <p>My problem is that I cannot make a smooth stroke even when I check the <strong>Smooth stroke</strong> in the <strong>Tool Options</strong> panel. When I do that the problem is less evident, but is still there.</p>
  
  <p>I believe the tablet is not the problem because in Krita the problem does not appear.</p>
  
  <p><img src="https://i.stack.imgur.com/kB8Qg.jpg" alt="Example of me trying to write my own name with the pencil tool and a stroke with the brush tool:"></p>
  
  <p>I have already uninstalled Gimp and installed it again and the problem persists.</p>
  
  <p>Can you please give some directions to solve the problem?</p>
