gdk:display-supports-composite (display)

display -- a gdk:display object

A boolean that is true if windows may be composited.

Returns true if the gdk:window-composited function can be used to redirect drawing on the window using compositing. Currently this only works on X11 with XComposite and XDamage extensions available. The gdk:display-supports-composite function has been deprecated since version 3.16 and should not be used in newly written code. Compositing is an outdated technology that only ever worked on X11.
