2.66 3D Viewport Bug

Can’t seem to solve this issue with the viewport. Running win7 64, 64bit version of blender 2.66, 550Ti, nVidia 314.07 drivers.

Bug not present in 2.65. Has anyone else run into this problem?

Check your viewport clip start value. The default is 0.1. Reducing it can show this effect

Yup, that solved it! I wonder if I’ve fiddled with it and forgot. Thanks!
