Nouveau - Jan 2012 - [Bug 45299] New: fullscreen GL window flickering with updates in other windows

https://bugs.freedesktop.org/show_bug.cgi?id=45299

             Bug #: 45299
           Summary: fullscreen GL window flickering with updates in other
                    windows
    Classification: Unclassified
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: bill at taniwha.org


This is with debian undstable xorg and blackbox, running quakeforge
(http://quakeforge.net/).

When quakeforge is running full screen and updates happen in another window
(eg, echoed console messages in the xterm from which I launched qf (eg,
nq-glx)). This does not happen with the LLVM driver (I had symbol problems with
a bad build of nouveau and wound up with the LLVM driver for a while).

a good test command line:
nq-glx +set vid_width WIDTH +set vid_height HEIGHT +set vid_fullscreen 1

where WIDTH and HEIGHT are the full size dimensions of the display. BTW,
vid_fullscreen can be changed while nq-glx is running, but vid_width and
vid_height cannot.

I Just tried it with blender in fullscreen mode with a compile going in another
xterm and the same problem occurred.

--- Comment #1 from Marcin Slusarz <marcin.slusarz at gmail.com> ---
This bug was fixed in march on xf86-video-nouveau side.

If you can't update xf86-video-nouveau, you can workaround it by disabling
pageflipping in xorg.conf (see man nouveau).
