Floorboard shining through

[Dontknow]

Why is my floorboard shining through when I zoom out?

[Erwin Edel]

Because the OpenGL workspace is optimised for working in 3D and not meant to be a perfect 3D presentation.

You get thin elements showing contours of things below if you zoom out far enough.

So software limitations.

If you render the view or save a 3D document, those lines will not show.
