These do not play well with each other. Lots of model abnormalities, like vertex stretching, incorrect z-order, certain elements drawn as black, etc. With fastmem off games run fine. Just wanted to let the devs know in case they didn't already. I apologize if you did know about it but Google and the issues page showed no such evidence. Anyway I'm running build 4.0-6078 from like 6 hours ago. If you need more info I will be glad to help.
