I would like to report an issue I have had with LE3 since day one. Not sure if anyone else has the same experience. As the title explains, some of the surfaces jitter (as in up and down) when camera is up close and is rotating. This happens with the standard materials and tutorial maps as well. When the surface is lit and has a normal map it looks like the diffuse is locked but the normal map jitters. In the animation below you can cleary see billboard jitter (in this case just the diffuse texture).
