In such cases, compositors like compton or picom can be used. In such a case, since the environment is bare-bones (in the order of 1 to 5 megabytes), it is not shipped with a compositor off the shelf. ![]() You would need to install a compositor separately if you are using a minimalistic desktop environment of window manager such as dwm, i3 or awesome. Even some window managers like Compiz, Enlightenment, KWin, Marco, Metacity, Muffin, Mutter, Xfwm, do compositing on their own. Note that most desktop environments (like gnome) come with their own integrated compositors. ![]() Each frame of each running application goes through the compositor.Ī compositor should be used if there is a need of transparency, transition animations, v-sync and similar aesthetic features. Maintaining a buffer like this makes it easy to add additional frames during a window state change, such as fade-in and fade-out animations. The off-screen buffer can be automatically merged into the parent window or merged by external programs, called compositing managers. Applications can then take the contents of that buffer and do whatever they like. The compositer causes an entire sub-tree of a window hierarchy to be rendered to an off-screen buffer. ![]()
