# What is Compositor?

*Development · Last updated: November 3, 2026*

It is the software layer that manages where windows appear on the screen and their visual interaction with each other.

## Overview

It is responsible for rendering windows in the operating system, transparency effects, shadows, and visibility calculations when windows overlap. Modern architectures replacing traditional window managers both enhance visual quality and ensure smooth window movement by utilizing the power of the graphics card. The software composites the images coming from the windows and sends the final pixel state to the monitor.

***Analogy:** It is like a stage director who arranges which scenery stands in the front and which actor stands in the back on a theater stage, and determines who the light hits.*

## How it works

It collects graphic data from applications, processes the position of windows and visual effects, and has the graphics card draw the final image.

## Where it is used

It is found in Linux display servers, the Wayland protocol, and the core graphics architecture of modern desktop operating systems.

## Commonly confused with

It is often confused directly with the graphics card driver, but while the driver manages the hardware, the compositor organizes the visual layers.

## Questions and answers

**Does it strain the graphics card?**

On modern hardware, it is quite lightweight and relieves the CPU by offloading the workload to the graphics card.

**Why is it important?**

It prevents screen tearing that occurs while windows are being moved and ensures modern visual effects run smoothly.
