When uploading a picture to a texture, glamor_upload_picture_to_texture calls glamor_pixmap_ensure_fbo to ensure that there is backing FBO. The FBO will be allocated if the picture's drawable pixmap does not have one already, which can fail when there is no GL memory left. glamor_upload_picture_to_texture checks that the call succeeded and will enter the failure path if it did not. However, unlike many other functions in glamor, this one has ret set to TRUE initially, so it needs to be set to FALSE when a failure happens. Otherwise, the error is not propagated and the failure path return TRUE. This leads to a fault when trying to access the FBO pointer later on.

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
