CS6 showing as pixelated on new MacBook Pro (10.10.5)

Has anyone else noticed this? Adobe is trying to say it's a "hardware" issue and pass me off to Apple, but it clearly is not (no other software is having this issue, just CS6, starting with the installer). I've spoken with Apple and they say it is most definitely not a hardware issue (if it were, you'd see it elsewhere on the computer, but everything else is golden).

I can't be the only person trying to run CS on a new Mac book!

Anyone?
