Mac: Window won't fit no matter what resolution I change it to

[emarihidari]

Hello,
I just downloaded the mac app for Ryzom and am super pumped to start playing, but ran into issues right away.
I went into character creation and realized the entire window is not showing. Naturally, I logged out, opened the app again and toggled with the resolution option. No matter which resolution I choose, it still has the same problem. The upper and lower halves of the screen are cut off, making me unable to even complete the character customization.
I'm running it on a Macbook air 11', Yosemite 10.10.2, with a display of 1366 x 768.
The app as a whole runs fine, with no lag or other issues. Other than only being able to see half the screen. I even maximized the window, but it didn't change.
Thanks for your help!
