## Name

glutRemoveOverlay — removes the overlay (if one exists) from the current window.

## C Specification

`void `glutRemoveOverlay`` | `(` | `);`

## Python Specification

``glutRemoveOverlay`` | `(` | `) → `None``

## Description

`glutRemoveOverlay` removes the overlay (if one exists). It is safe to call `glutRemoveOverlay` even if no overlay is currently established—it does nothing in this case. Implicitly, the window's layer in use changes to the normal plane immediately once the overlay is removed.

If the program intends to re-establish the overlay later, it is typically faster and less resource intensive to use `glutHideOverlay` and `glutShowOverlay` to simply change the display status of the overlay.
