Mac Dynasty Shields+Map Border Glitch/Bug

[TedToaster22]

I've found that I'm able to run CKII perfectly fine on my Windows laptop, but the Mac desktop is a different story. The game loads fine but when I go to the map to pick a character I find the Dynasty Shields and Map Border (as in the border around the entire map, not individual realms) to blink between it's usually appearance and just a plain black. The problem persists if I try to start a game, and makes said game very laggy and unplayable. Any tips?

I too am having this problem. So far I haven't found any solutiuon...

Check your graphics card. Apparently mine wasn't new enough.

OS X 10.8 has much better video drivers than earlier ones, so upgrade to that if you can.
