I think there was an issue with retina in current public build. I believe it is fixed for the next public build release according to the build changelog on the team wiki.
In the next update I believe. I'm going from the team wiki build changelog. Only the devs can answer if it will be included/fixed in the next public release.
if someone has this problem, go to applcations folder 2 open de visionaire package3 go to ressources,4 right click or read visinaire player and chosse open in low resolution.....
