A compositing window manager, or compositor is a window manager that provides applications with an off-screen buffer for each window.
A compositing window manager, or compositor, is a window manager that provides applications with an off-screen buffer for each window. The window manager composites the window buffers into an image representing the screen and writes the result into the display memory.
A compositing window manager is a component of a computer's graphical user interface that draws windows and their borders. It also controls how they display and interact with each other, and with the rest of the desktop environment. The main difference between a compositing window manager and other window managers is that instead of outputting to a common screen, programs each output first to a separate and independent buffer, or temporary location inside the computer, where they can be manipulated before they are shown.
