Low window resolution on Retina display

[richartkeil]

Hey there,

I'm using ArtRage 3 Studio Pro (3.5.12) on a MacBook (OS X 10.11.6). Sadly there seems to be a bug concerning the window resolution. I tried to screenshot the problem, but in the image the ArtRage window looks much smoother now. In front of the screen I can see every pixel of the ArtRage window, while the desktop background is perfectly sharp. When I worked with ArtRage on Windows, everything was fine.

Do you know this issue? Thanks in advance (:
