I'm just reporting this in case someone hasn't run into this yet.
We had a situation dealing with large assemblies that have components shrink-wrapped where the sections wouldn't display properly in the drawing.
Some of the shrink-wrapped components would be displayed in the wrong location outside the assembly.
We tried new workspaces, different PCs with different video cards nothing worked until we tried
a machine with build 160 loaded on it.
This solved the problem.
FYI
