Video Display Problems Since Upgrade to 9.0.24172

I believe I started having these video anamolies (see screen shot) round the time I upgrade to 9.0.24172. I'm running OSX 10.8.5. I've been holding my breath since I heard a bunch of problems when it first came out. I'm using a macbook pro retina (2012) version with 16GB Ram and half of video ram (512) allocated. Directx10 and vertical sync selected. I've also got 2 of the 8 cpu's selected. Finally, I always run on 2 monitors. my apple thunderbolt and a 1980x1024 HP (with the macbook itself closed).
