Mesh becomes see-through in edit mode As illustrated in the screenshot, the geometry on the non-visible part of the mesh is visible in edit mode, even when the viewport shading mode is set to Solid.



It gets difficult to see and select geometry efficiently when this happens. I've observed that this happens when I set the units to centimeters (also in the screenshot).

Is this a bug? Is there a workaround? If this is a bug, where is the best place to report it?

It's not a bug, it's a feature! It's called "Limit Selection to visible", and it limits selection to the visible faces. To enable the Limiting, you have to click this button.
