I found a work around, but here's the issue I had.



During the first 3 intro screens (Amplitude, Iceberg Interactive and Endless Legend) but before the animated menu (by the way, I only get 2 of them - Roving Clans and Broken Lords) I have a black line across the screen that begins with the steam overlay and disappears when it does during the middle of the 3 screen intro. I had lowered my graphics setting (to speed up the game) and that seemed to fix this line.



I'm running 10.9.5 osx. Intel core i7 with 8gb ram (as spec'd out from apple) w/HD4000 ( Space Troll told me this is a low spec videocard... which I know).



Here's a pic I took with my phone.
