Material preview artifacts

Import the attached speedtree asset. The material view will be glitched. Disabling the world position offset input and reenabling seems to help.

This issue did not occur in 4.10.4 and does not occur in 4.12 Dev-Main - CL-2930868.

This issue is only happening in 4.11.0 that I can see.

1. Import attached asset
2. Go to the Content Browser
3. Select any glitched looking material

Regression: Yes

Results: material preview has artifacts

Expected: Material preview will not have artifacts
