I'm using the 15" Retina Macbook Pro. Other specs are pictured in the attached screenshot.
As you can see, the menu bar looks extremely broken and the window is sized incorrectly, leading to areas which don't repaint properly. I have Windows set to 192DPI.
Windows's DPI virtualization has gone into effect but the option to disable it in the shortcut properties is greyed out since it is a 64-bit binary.
Dialogs other than the main one are generally less broken, although there are tiny elements in the About box and file dialogs.
