Occasionally after a restart I get flickering showing stale buffers on Krillin.

A video showing the problem: http://people.ubuntu.com/~afrantzis/krillin-strange-flicker.mkv

The HWC log indicates that we somehow end up with an unexpected buffer when compositing:

set list():
 # | handle
 0 | 0x3f4770 <====== This buffer is the odd one out
 1 | 0x3f4188

...

set list():
 # | handle
 0 | 0xac202978
 1 | 0x3f4188

...

set list():
 # | handle
 0 | 0xac203f60
 1 | 0x3f4188
