EMap & Zebra only display in Shaded Mode

EMap and Zebra display only if the viewport is in Shaded model. V6 WIP. @markintheozarks reported a similar or the same problem earlier today. EMap and curviture analysis not responding well @John_Brock said “It looks fine here” but he may have been in Shaded mode when he checked. The same problem was previously reported: 1-31-17 WIP e-map doesn’t work in all display modes

I tried all display modes with EMap and it works fine.
However, I did have to adjust the render mesh or run ClearAllMeshes to get Emap to initially refresh.

I was able to repeat it and have added it here:

@John_Brock ClearAllMeshes does not fix the problem for me.

How about dragging the mesh slider in the EMap or CurvatureAnalysis commands?
The trick is getting Rhino to replace the existing analysis mesh.
That’s what the bug report is about.
