--- Comment #48 from Ray Strode [halfline] <rstrode at redhat.com> ---
So i did a scratch patch (will attach it) just to get some timings with and
without christian's fix:

a time to draw: 8.5ms
b time from wl_event_loop_dispatch until wl_surface_commit is called: 4.4ms
c time spent allocating the texture in mutter: 6ms
d time spent copying the buffer to the texture in mutter: 5ms

with patch

a time to draw: 3.8ms
b time from wl_event_loop_dispatch until wl_surface_commit is called: .055ms
c time spent allocating the texture in mutter: .004ms
d time spent copying the buffer to the texture in mutter: 5.7ms
