miDbePositionWindow allocates two pixmaps: a front buffer, and a back buffer. If the buffers are supposed to be initialized, it validates a GC against the front buffer, then uses it to fill and/or copy both the front buffer *and* the back buffer, without revalidating. If the acceleration architecture needs different GC funcs for the two pixmaps -- for example if allocation of the front buffer exhausted video memory -- then this can cause crashes because the GC is not validated for the back buffer pixmap. Fix this by performing the rendering for the front buffer first, then revalidating against the back buffer before performing the back buffer rendering.

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: http://en.wikipedia.org/wiki/X_server All questions regarding this software should be directed at the Xorg mailing list: http://lists.freedesktop.org/mailman/listinfo/xorg Please submit bug reports to the Xorg bugzilla: https://bugs.freedesktop.org/enter_bug.cgi?product=xorg The master development code repository can be found at: git://anongit.freedesktop.org/git/xorg/xserver http://cgit.freedesktop.org/xorg/xserver For patch submission instructions, see: http://www.x.org/wiki/Development/Documentation/SubmittingPatches For more information on the git code manager, see: http://wiki.x.org/wiki/GitPage
