When attempting to go full-screen on my rMBP at native resolution (2880x1400), the game only renders in the top-left corner of the screen and the mouse doesn't seem to work at all. It works fine if I render at "virtual" resolution (1440x900), although it looks awful since AA isn't supported.

It also crashes if I switch to windowed mode (submitted a Bug Report for that one).

Thanks. I didn't enable retina support but I'll see about trying to do that.

Unfortunately we don't have any retina-resolution devices or monitors to test against. Where are you selecting 'virtual resolution of 1440x900'? in the System Preferences -> Display?

No -- in VO itself. If I tell VO to render at 1440x900, it sort of works. If I tell VO to render at 2880x1800, it only displays in the upper-left quarter of the screen and can't be interacted with.

Ah. I think I kinda know what's going on but haven't been able to reproduce the problem due to lack of retina hardware to be able to test my theory.
