I have two compositions with exactly the same font settings, however the text in one of the comps has now gone all pixelated. it does not matter what font i change it to it remains the same. All the settings in the text are the same too. Has anyone ever experienced this? See screen shots.
Do you have the Dissolve transfer mode applied? You might have accidentally done it by pressing Shift + or Shift -
You could also have Ray-traced 3D turned on. You don't need that for this project.
