To date, the only Retina Display issues that I have seen, have been related to Photoshop CS 6, and Premiere Elements 11. That does not mean that users are not having issues with Retina and PrPro, but just that I have not seen them.
In Photoshop, Chris Cox, an Adobe Engineer, allows that there ARE issues with Retina, and that Apple and Adobe are working on a fix. Not sure how that might, or might not apply to other Adobe progrms.
Good luck,
