Macintosh

Hey, this is a crosspost from the issues/workarounds forum, as it seems to be mac-specific (I play EVE on both):

I'm getting a bug where my overview just randomly...disappears. It acts kind of like this bug: https://forums.eveonline.com/default.aspx?g=posts&t=39671&p=13 but without the windows going black thing. It occurs when I'm using two clients (although I frequently am, so I can't be sure that's the only time it happens).

I'm playing on OS X, on a mid-2012 retina macbook pro:

Processor 2.6 GHz Intel Core i7
Memory 16 GB 1600 MHz DDR3
Graphics NVIDIA GeForce GT 650M 1024 MB
Software Mac OS X Lion 10.7.5 (11G63)

I most often see it when tabbing back and forth between clients. Usually, the overview disappears, although once, the selected item window disappeared too.

What do?
