Hi,
I've got a Windows 2012 R2 VM on VMWare Fusion 6.0.2. As soon as I enable "Use resolution for Retina display option", and maximize the window to the 1400x900 resolution I run on my Mac, the Windows interface becomes unusable. The screen does not redraw corresponding to any user input (mouse or keyboard). E.g. I can mouse over the start button or click any interface elements and nothing happens.
If I resize the VM window and allow the screen to redraw, eventually I get to a point where the screen is scaled correctly and input is registered properly again.
Attached are a couple screenshots:
In this image the window is "maximized", the VM isn't rescaled properly, and mouse/keyboard input doesn't register (or at least the screen doesn't update to show that input).
In this image, the window is sized down enough so that the scaling in the VM is crisp, and the screen redraws and handles input properly.
This does not happen with my Windows 2008 R2 VM.
