Thanks Pekka!

I have pulled Daniel Stone's code:

But weston could not be started normally,the  error log is:

    Switch to global output repaint timer

    In preparation for grouping output repaint together where possible,
    switch the per-output repaint timer, to a global timer which iterates
    across all outputs.

    This is implemented by storing the absolute time for the next repaint
    for each output locally, and maintaining a global timer which iterates
    all of them, scheduling the repaint for the first available time.
