Default CM11 new theme engine

I noticed recently that CM has released a revamped theme engine. I tried using the theme engine in the recent Mahdi rom but found it very buggy to the extent that I would be greeted with various FC's, occasionally ending with my phone crashing.

Is this a known issue with the new theme engine in that it's buggy and still kind of beta, or more likely a problem Mahdi side?
