Highlight in viewport ?

[CinnamonMetal]

I don't have any lights in the scene, although how do I eliminate or fix this highlight that appears on the mesh when rotating the mesh in the viewport ?

That's really bizarre. Does adjusting the viewport clipping planes in the display options do anything? 

'd' in viewport, Viewport tab, Clipping options.

Is that packed objects or instances? If so its the viewport culling the instances.

It's packed objects. 

The higher I set the value for Scene Polygon Limit, the less of the `shadow` on the mesh I see but the slower the object is to navigate in the viewport ? Although the `shadow` even when the Scene Polygon Limit is set to an extremely high value, is still present on the mesh ?

The shadow is the individual bounding boxes of the instances being culled. It looks like a solid blob because they're all overlapping. This is a feature that prevents instancing from generating a massive number of polygons to draw, which can slow your redraws down (and if you're on Windows, cause the driver to reset). You can tweak the Scene Polygon Limit to balance redraw speed with the # of instances actually drawn.

@malexanderWhere is the polygon Limit, within the Scene tab of the Display Options ?

[malexander]

It's in the Optimization tab of the Display Options.

@malexander It's the same setting I had changed, when I set it too 1000 basically the `shadow` appearance disappears although my viewport is slower; as you mention.
