Graphics Corruption - El Capitan Beta

[J B]

Hello, I've been playing Cities on my Mac for months and it worked fine in OS X Yosemite and also under El Capitan until a few weeks ago. A new version of the El Capitan beta appears to have broken the game - it runs fine until I start or reload a game. The game itself above the toolbar is a bunch of corrupted graphics:



Unfortunately, the OS X updates since I first got this problem have not fixed it. I was hoping today's new build would help but there is no change. I wonder if Apple changed something with the graphics driver. I have reported this issue with Apple too.

I am running an iMac, late 2013 model, 27 inch. The graphics card is a NVIDIA GeForce GT 755M 1024 MB.

I have had the same issue. As of I want to say update 11.11 update I have severe graphical issues when I start a new game.

I wonder if because they are updating Metal giving more direct access to the GPU for games that it broke the game until the final release.

El Capitan beta

That is while it is called a beta. Beta phase generally begins when the software is feature complete but likely to contain a number of known or unknown bugs. Don't touch a beta unless you know what you are doing.
Can you re-roll to a non beta version?
