For a data point, using the pre-built wheezy/0.27 referenced above I
see some improvement in the eglfs version, but it still stutter
enough to be unwatchable while xcb is fine as long as you avoid the
OSD.

Source video is 720p60 and 1080i30 to a 1080p60 display via hdmi.
Raspberry Pi2 overclocked to 1GHz.
