Thanks,
Is there any chance they are aware of the Radeon graphics bugs? There are several graphics driver problems with newer graphic cards, the only solution at this point is to install the 17.6.2 version of the graphics driver - from 2013!
I hope you will pass along the information that the newer graphics cards cause issues regardless of Mac or PC. There are several recent threads regarding the Radeon cards, but I suspect many of the launch and display issues have to do with a graphic driver incompatibility.
