    I had this problem on MBP with Nvidia 750M. Now I have a new MBP with AMD 560, and the problem does not occur. So I'd guess it's related to either GPU generation or manufacturer.

    Hi guys, it would be great if you could fix this one. It's such a pity that now TC2 finally works on the mac, I still cannot use it because of this issue ...
