        Description

        In 1.3.1 the use of shared memory extension has been disabled when the
        X server is running in Xinerama mode. This was done to work around
        some Xinerama/ddx bugs, in particular,
         4522502: pgx32 24+8 mode: XShmPutImage has problems with pixels with MSB set

        The bug has already been fixed and the patch is available, so we should
        re-enable use of shared memory as it may greatly improve performance
        in this case for some applications.
