Hello,
it’s normal that the display in demo mode with starter is like the screenshot below
the stroke of the circle is not perfect …it’s a limitation due to demo mode ?
thanks for the response 
its seems no anti-aliasing has been used, but remember corona sdk is a game engine not a graphics one. You could easily use your own images of course.
and who do you fo for enable anti-aliasing ?
i have searched in the doc, it seems to be in config.lua but i found nothing
Anti-Aliasing is disabled in Corona right now, no matter what subscription level you are on. It’s disabled internally, which means you cannot enable it.
Use images instead of vectors if you need smooth lines, for the time being.
ok thanks
