title: Pango text gets blurring when GL viewport is changed
body: <p>I am working with a piece of code which was rendering a texture containing text written using Pango, in a particular GL viewport. I have now had to change the viewport, and put the texture at a different z-distance, however, the text has become blurry. I have tried changing the font size, style, etc., but no success. </p>
  
  <p>I am new to Pango, and this is a rather generic question, but any pointers to what could be the reason will be helpful.</p>
