Distance Field Mesh default resolution artifacts on some shape meshes

Distance Fields generated for the 4 basic static mesh assets in the modes panel appear to have artifacts or low resolution. This is only affecting certain shapes that I can see. Adding in assets from the starter pack for the more complex assets appear correct, however the shapes like Cube, cylinder, cone, and sphere appear to have these artifacts.

This appears to have been resolved in 4.12 (Main) though.

1. Open UE 4.11 Preview release
2. Enable Distance Fields for the project
3. Restart the project if not already enabled.
4. Drag in a static mesh from the Modes panel (cube, sphere, cone, or cylinder)

Regression: Yes

Results: Generated Distance Field Mesh is low resolution or has some artifacts that are lower quality.

Expected: Distance Field Resolution of the mesh should be higher quality for default resolution of 1.
