DebugPresent() crashed the server when a dri3 drawable was closed while a pageflipped present was still pending, due to vblank->window-> Null-Ptr deref, so debug builds caused new problems to debug. E.g., glXSwapBuffers(...); glXDestroyWindow(...); -> Pageflip for non-existent window completes -> boom. Also often happens when switching desktop compositor on/off due to Present unflips, or when logging out of session. Also add info if a Present is queued for copyswap or pageflip, if the present is vsynced, and the serial no of the Present request, to aid debugging of pageflip and vsync issues. The serial number is useful as Mesa's dri3/present backend encodes its sendSBC in the serial number, so one can easily correlate server debug output with Mesa and with the SBC values returned to actual OpenGL client applications via OML_sync_control and INTEL_swap_events extension, makes debugging quite a bit more easy. Please also cherry-pick this for a 1.16.x stable update.

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
