When a pixmap is created with a backing FBO, the FBO should be cleared to avoid rendering uninitialized memory. This could happen when the pixmap is rendered without being filled in its entirety. One example is when a top-level window without a background is resized. The pixmap would be reallocated to prepare for more pixels, but uninitialized memory would be rendered in the resize offset until the client sends a frame that fills these additional pixels. Another example is when a new top-level window is created without a background. Uninitialized memory would be rendered after the pixmap is allocated and before the client sends its first frame. This issue is only apparent in OpenGL implementations that don't zero the VRAM of allocated buffers by default, such as RadeonSI.

X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server
