This is odd since the only thing installer updated on your 13.04 was libva/vaapi intel drivers that are multimedia (video encoding/decoding) stuff and doesn't touch graphics acceleration.
how frequent you see this issue? started only after installer?
Hello I tried installing the 32 bit 13.04 driver and rebooted and everything is screwy now.... Maybe it's something with Compiz I don't know... Here's a screenshot:
