Image quality worsens

Hello, I’ve got some problems:

  1. There is a fragment as a circle, png “cen.png” (see attach file) file, in my game. The circle reduces automatically, but in process of reduction using “transition.to” the quality of the circle worsens. How can I fix this? I tried not to use PNG and draw a circle using “display.newCircle”, but the result is still unsatisfactory.
  2. There is also a semicircle “90.png” (see attach file) in the game. It goes around the circle. During the turning quality of the object is jumping. Is it possible to fix it somehow or replace?
