Instead of complex wrap/unwrap trickery in the error path, just protect the DestroyPixmap() handlers from half-initialized state. This not just makes the code flow simpler and easier to understand, but also clears the road for decoupling the extension specific pixmap destructor logic from the ScreenRec proc vectors (*1). *1) see: https://gitlab.freedesktop.org/xorg/xserver/-/issues/1755 Signed-off-by: Enrico Weigelt, metux IT consult <info@metux.net>
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.
