--- Comment #5 from Chris Wilson <chris at chris-wilson.co.uk> ---
Hmm, the other question here is whether fbc is enabled?

"FBC can show stale data when using 180 degree hardware rotation of the primary
display plane.
WA: Do not enable FBC when using hardware 180 degree rotation on the primary
display plane."
