Olivier Fourdan e196535abb dix: Clear device sprite after free in AttachDevice() 
The code in AttachDevice() may free the dev->spriteInfo->sprite under
some circumstances and later call GetCurrentRootWindow() which uses
the same dev->spriteInfo->sprite.

While it seems unlikely that this is actually an issue, considering the
cases where one or the other get called, it still makes the code look
suspicious.

Make sure to clear set dev->spriteInfo->sprite to NULL  immediately
after it's freed to avoid any confusion, even if only to clarify the
code.

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

All questions regarding this software should be directed at the Xorg mailing list:
