--- Comment #5 from Paulo Zanoni <przanoni at gmail.com> ---
It's expected that when you switch to multihead you may end up not having
enough stolen memory for a 1:1 CFB and that may cause the code to reduce the
CFB size. That's fine and expected. Due to that, I updated the bug title in
order to avoid confusion. The "i915.enable_fbc=0" test should help finding out
if this is indeed a problem related with FBC.
