# NSOpenGLPFABackingStore

A Boolean attribute. If present, this attribute indicates that OpenGL only considers renderers that have a back color buffer the full size of the drawable (regardless of window visibility) and that guarantee the back buffer contents to be valid after a call to NSOpenGLContext object’s flushBuffer().

## Declaration

```swift
var NSOpenGLPFABackingStore: Int { get }
```
