That does sound related to "retina displays", or more specifically "HiDPI mode".  With non-retina displays, 1 point = 1 pixel, but with retina 1 point = 2x2 pixels.

Is your thunderbolt display retina?  Could you test on a non-retina Mac?  You can also enable HiDPI mode on non-retina Macs using Quartz Debug, or maybe even SystemPreferences>Displays these days.  These tests should at least be enough to confirm HiDPI mode is the issue here.

Cheers,
