This file uses displacements and adaptive subdivision, (experimental mode on). In this scene certain simple objects seem to disappear in anything but the rendered views, and they are un-manipulable (cannot move, scale, or rotate them).
In the rendered view, all three overhead objects are visible, and the pebbles on the ground (they look distorted) are visible. None of the objects (the three overhead or the pebbles) can be selected or manipulated; even though in the properties panel on the right, we can see that "show in viewports", "show in renders", and "selectable" are all checked. In the solid view, none of the objects listed above are visible, selectable, or manipulable.
Here is the .blend.
