The "problematic one" is a 15", also running its native retina resolution (1440x900).
Ok, that's not that much difference, approximately 20 MB per frame instead of approximately 16 MB per frame (+25%). I'm out of good ideas to guess how that would make a real difference.

I've already tried to explain that. Remember the blue and brown pixels? ;)

Can confirm that I have this exact same problem: see viewtopic.php?f=8&t=102515.

The same fix/workaround (low resolution mode) and the same side effect of that fix -- very blurry rendering of everything on the VM. Text rendered in a small font size is the most problematic thing, it's barely readable. The overall effect appears similar to how excessive antialiasing can sometimes look.
