title: Artifacts when mapping screen coordinates to texture texels
body: <p>Alright guys so my issue is very peculiar. I am mapping a texture onto a quad. The texture contains font values generated with Free Type. When I render it to the screen it has artifacts. "Hola, elienay, y Khaleexy" is the rendered quad/texture.</p>

  <p>However, when I go into shader debug mode and look at the texture to see why it has artifacts, I do not get artifacts. The quad is rendered perfectly and the back buffer has the final colors correctly without 1 single artifact; see below.

  <p>Alright, so you guys see what I'm talking about? The quad is being rendered and mapped perfectly to the texture but it seems that the issue is when the application presents the back buffer to the screen. Any ideas on what this could be caused by and how to fix it??</p>
  
  <p>Below are a couple more screen shots with different random characters. To show how the artifacts are present only when not rendering the scene in debug mode.
