Window compositing provides applications with a separate and independent buffer for each window. A window manager can composite output from these separate buffers onto a common desktop. It can also affect how the buffers are displayed and interact with each other, along with the rest of the desktop environment. Enabling window compositing on IGEL thin clients requires certain configuration options to be selected.
